Vitamin C and its effects on the skin

Vitamin C is one of the most studied and most frequently used active ingredients in cosmetology. Valued for its versatile effects - from lightening discolorations, through stimulating collagen production, to antioxidant protection - it has become an indispensable element of skin care at any age. Its effectiveness is confirmed by numerous scientific studies, and cosmetics with this vitamin are extremely popular among dermatologists and cosmetologists around the world. In this article, we will explain exactly how vitamin C works on the skin, what problems it can help with, and how to properly introduce it into your daily care.

What is vitamin C in cosmetics?

Definition and properties

Vitamin C (L-ascorbic acid) is a water-soluble vitamin with a strong antioxidant effect. It is essential for the proper functioning of the body, including skin health. Humans do not synthesize vitamin C on their own, so it must be supplied from the outside - both in the diet and through external care.

In cosmetology, this vitamin is used primarily due to three key properties:

  • neutralizes free radicals and has antioxidant properties,
  • participates in collagen synthesis,
  • lightens discolorations and evens out skin tone.

As shown in studies (Pullar et al., Nutrients , 2017), topical application of vitamin C can significantly improve the condition of the skin, reducing signs of aging and improving hydration.

Forms used in cosmetics

Pure ascorbic acid is characterized by high biological activity, but it also has certain limitations - it is unstable, easily oxidized by light, air and high temperature. Therefore, more stable derivatives of vitamin C are often used in cosmetics, which also show high care effectiveness and are more resistant to storage conditions.

The most common forms of vitamin C in cosmetics include:

  • Ascorbyl Glucoside – a stable water-soluble form that, once absorbed into the skin, transforms into active ascorbic acid (Badal et al., Journal of Cosmetic Dermatology , 2017).
  • Magnesium Ascorbyl Phosphate (MAP) – a more gentle form, especially recommended for sensitive and vascular skin.
  • Sodium Ascorbyl Phosphate (SAP) – also has antibacterial properties and may support the treatment of acne-prone skin (Huh et al., Dermatologic Therapy , 2016).
  • Tetrahexyldecyl Ascorbate (THD Ascorbate) – a highly stable, lipophilic form of vitamin C, perfectly penetrating the skin and effective even at lower concentrations (Huang et al., Journal of Cosmetic Dermatology , 2007).

Natural sources of vitamins in care

Some cosmetics also use plant extracts rich in natural vitamin C, such as:

  • Amla (Phyllanthus emblica, Emblica Officinalis)
  • acerola (Malpighia emarginata),
  • wild rose (Rosa canina),
  • camu camu (Myrciaria dubia).

Although the amounts of active vitamin C in extracts may be less compared to pure synthetic forms, they often occur in synergy with other bioactive compounds, which further supports skin care (Telang, Indian Dermatology Online Journal , 2013).

Main benefits for skin

Antioxidant effect - neutralization of free radicals

It is one of the strongest natural antioxidants used in dermatology. Its main role is to neutralize free radicals — reactive oxygen species (ROS), which are created, among others, under the influence of UV radiation, air pollution, cigarette smoke and oxidative stress.

Laboratory studies have shown that topical application of vitamin C can reduce the level of free radical-induced DNA and cellular protein damage by as much as 40–60% (Humbert et al., Journal of the American Academy of Dermatology , 2003). This means slowing down the skin aging process, reducing micro-inflammatory changes and protecting the epidermal barrier.

It is worth emphasizing that the antioxidant protection of vitamin C is particularly important during periods of intense exposure to UV radiation – which is why it is so often combined with sunscreens (Lin et al., Journal of Investigative Dermatology , 2005).

Lightening discolorations and evening out skin tone

It inhibits the activity of tyrosinase, an enzyme involved in melanin synthesis (Barbagallo et al., Dermatology Research and Practice , 2010). Thanks to this, it has a depigmenting effect:

  • lightens post-inflammatory discolorations,
  • reduces sun spots,
  • evens out skin tone.

In clinical studies, the use of a serum with 10% vitamin C for 12 weeks reduced the visibility of discolorations by about 25-30% (Farris et al., Dermatologic Surgery , 2005). The effects are more pronounced with systematic use and in combination with other depigmenting ingredients, e.g. ferulic acid or niacinamide.

Stimulation of collagen synthesis and improvement of skin elasticity

It plays a key role in the hydroxylation of proline and lysine — amino acids necessary for the stabilization and proper formation of collagen fibers (Phillips et al., American Journal of Clinical Nutrition , 2017). This means that this vitamin:

  • increases the production of new collagen (mainly type I and III),
  • improves skin density,
  • smoothes fine wrinkles.

Studies have shown that after 6 months of using a serum with 10% vitamin C, the thickness of the dermis increased by an average of 30% and the amount of new collagen increased by about 40% (Traikovich, Journal of Dermatologic Surgery and Oncology , 1999).

This is one of the reasons why the vitamin is so often recommended in the care of mature skin and anti-aging prevention.

Strengthening the skin barrier and moisturizing

It also participates in the synthesis of epidermal lipids, such as ceramides and fatty acids, which helps maintain the proper function of the skin's hydrolipid barrier (Pinnell et al., Archives of Dermatology , 2001). This results in:

  • improving the skin's moisture level,
  • reduction of transepidermal water loss (TEWL),
  • reduced sensitivity to irritating factors.

Studies have shown that the skin of people who applied topical vitamin C showed an average of 15–20% better hydration than the control group after just a few weeks of use (Fuchs et al., Dermatology , 1998).

Anti-inflammatory and supportive effect in acne therapy

A growing body of research also points to the anti-inflammatory properties of vitamin C. It can reduce redness, soothe acne symptoms, and support skin healing processes (Huh et al., Dermatologic Therapy , 2016).

For problematic skin, stable forms of vitamin C are often recommended, such as Sodium Ascorbyl Phosphate (SAP), which have additional antibacterial effects on Propionibacterium acnes, the bacterium responsible for acne breakouts.

Who is vitamin C recommended for?

Mature skin

This vitamin is one of the key ingredients in anti-aging care. After the age of 30, the natural production of collagen in the skin begins to gradually decline, which leads to loss of firmness, the appearance of fine wrinkles and skin laxity. By stimulating the synthesis of collagen types I and III, it can significantly slow down these processes. Studies show that regular application of vitamin C increases skin density and improves its elasticity by up to 20-40% after several months of use (Traikovich, J Dermatol Surg Oncol , 1999). Therefore, serums or creams with vitamin C are especially recommended as an element of daily skin aging prevention.

Skin with discoloration

Sun discoloration, melasma, acne spots or uneven skin tone are problems that vitamin C can effectively deal with. It inhibits the activity of the tyrosinase enzyme, which is key in the synthesis of melanin, which translates into a reduction of existing pigmentation changes and prevents the formation of new ones (Barbagallo et al., Dermatol Res Pract , 2010). The effects of skin lightening can be seen after 8–12 weeks of daily use of preparations containing at least 10% stable vitamin C.

Capillary skin

People with vascular skin are often afraid of strong active ingredients, but a properly selected form of vitamin C can bring many benefits. Thanks to its antioxidant properties, the vitamin strengthens the walls of blood vessels, reduces redness and inflammation. Stable derivatives of vitamin C (e.g. Magnesium Ascorbyl Phosphate or 3-O-Ethyl Ascorbic Acid) are safer for this type of skin, reducing the risk of irritation while maintaining full care effectiveness.

Oily and acne skin

Vitamin C also has anti-inflammatory effects, making it valuable in the care of oily, acne-prone, and problematic skin. Studies have shown that forms such as Sodium Ascorbyl Phosphate (SAP) limit the growth of Cutibacterium acnes (formerly Propionibacterium acnes ) bacteria responsible for the development of acne lesions (Huh et al., Dermatol Ther , 2016). Additionally, vitamin C helps reduce post-inflammatory hyperpigmentation (PIH), evens out skin tone, and regulates sebum secretion.

Sensitive Skin - What Forms of Vitamin C to Choose

Sensitive skin requires special care when choosing vitamin C. Classic ascorbic acid (L-Ascorbic Acid) in higher concentrations can cause redness, burning and irritation. Therefore, for sensitive skin it is recommended to use stable and better tolerated forms, such as:

  • Magnesium Ascorbyl Phosphate (MAP) – a mild, water-based derivative of vitamin C, without irritating effects,
  • 3-O-Ethyl Ascorbic Acid - an exceptionally stable and well-penetrating form, minimizing the risk of skin reactions,
  • Ascorbyl Glucoside – gentle and gradually releases vitamin C into the skin.

Thanks to this, people with reactive skin can also safely enjoy the benefits of vitamin C.

How to use vitamin C in skin care?

What time of day is it best to take vitamin C?

Vitamin C can be applied both in the morning and in the evening, however, due to its antioxidant and protective effects, in practice it is most often recommended to apply it in the morning – under a cream with SPF filter. Vitamin C neutralizes free radicals created by UV and environmental pollution, thus strengthening sun protection. Studies (Lin et al., J Invest Dermatol , 2005) confirm that combining vitamin C with UV filters increases the overall protection of the skin against photoaging by up to 50–60%.

Applying vitamin C in the evening is also beneficial, especially in anti-wrinkle and depigmentation treatments, as it can help skin regenerate while you sleep.

In what order should I apply vitamin C?

  • Skin cleansing – gentle gel, emulsion or foam.
  • Toning – a tonic that restores the skin’s pH.
  • Vitamin C Serum – preferably on slightly damp skin (greater penetration).
  • Moisturizing cream – protects and strengthens the hydrolipid barrier.
  • SPF cream (morning) – sun protection is key when using vitamin C.

What concentration of vitamin C should I choose?

The concentration is selected according to the needs and tolerance of the skin:

Skin type Recommended concentration Recommended form
Sensitive skin 3-5% Magnesium Ascorbyl Phosphate, Ascorbyl Glucoside
Oily and combination skin 5-10% Sodium Ascorbyl Phosphate, 3-O-Ethyl Ascorbic Acid
Mature skin and discoloration 10-20% L-Ascorbic Acid, 3-O-Ethyl Ascorbic Acid

Studies show that even a 10% concentration of L-Ascorbic Acid brings significant results in reducing wrinkles and discoloration after 12 weeks of use (Farris et al., Dermatol Surg , 2005).

What to combine vitamin C with to increase its effectiveness?

  • Vitamin E (Tocopherol) – synergistic antioxidant action, protection of skin lipids.
  • Tranexamic acid – supports vitamin C in reducing discoloration.
  • Niacinamide – additional regulation of sebaceous glands, improvement of the skin barrier.
  • Hyaluronic acid – intense hydration, improved skin elasticity.

When should you be cautious?

  • For active inflammatory conditions of the skin.
  • During intensive acid treatments (e.g. retinoids, AHA/BHA acids).
  • In case of allergies to auxiliary ingredients of the serum (preservatives, stabilizers).

For people with very sensitive skin, it is best to start the treatment with low concentrations and stable forms of vitamin C, such as ethylated vitamin C (3-O-Ethyl Ascorbic Acid), used, among others, in the Orientana series.

The most common mistakes when using vitamin C

Use of unstable forms

One of the basic mistakes is choosing products containing an unstable form of ascorbic acid without appropriate stabilizers. Pure L-Ascorbic Acid oxidizes very quickly in contact with air and light, losing its properties and even irritating to the skin. Oxidized vitamin C can take on a yellow or brown color - such a product should no longer be used.

That is why it is so important to choose stable vitamin C derivatives (such as 3-O-Ethyl Ascorbic Acid, Magnesium Ascorbyl Phosphate or Sodium Ascorbyl Phosphate), which remain durable and effective throughout the entire use of the cosmetic.

No sun protection

Vitamin C has a protective effect, but it does not replace UV filters. Unfortunately, a common mistake is to not use a cream with a filter, which destroys some of the effects of the therapy. Under the influence of the sun, pigmentation and oxidation processes in the skin intensify.

Clinical studies clearly show that only the combination of vitamin C and photoprotection provides full antioxidant protection and prevents the formation of new discolorations (Lin et al., J Invest Dermatol , 2005).

Concentrations too high at the beginning of the treatment

Many people immediately reach for high concentrations of vitamin C (15-20%), which can lead to irritation, burning, redness and dry skin, especially in sensitive skin. The treatment should be started with lower concentrations (5-10%), and only after a few weeks the doses should be increased as the skin adapts.

Inappropriate combination with other active substances

Vitamin C in the form of pure ascorbic acid has a low pH, which is why it can react with some active ingredients. Particular caution should be exercised when used concurrently with:

  • strong AHA/BHA acids,
  • retinoids,
  • copper peptides.

Such combinations can overload the skin barrier and increase the risk of irritation. In practice, it is recommended to apply vitamin C in the morning and retinoids in the evening, with a break of several hours between applications.

Storage in inappropriate conditions

Vitamin C is sensitive to light, air and high temperatures. Products should be stored in tightly closed, opaque bottles (amber glass, airless packaging), in a cool and dry place. Avoiding exposure to sunlight and high temperatures significantly prolongs the durability of the serum.

Irregular use

The effectiveness of vitamin C depends on regularity. Irregular use does not allow for full activation of collagenogenesis processes, lightening of discolorations or neutralization of free radicals. For noticeable effects, daily application is necessary for at least 8-12 weeks.

Vitamin C plays a unique role in skin care, combining a wide spectrum of action: from strong antioxidant protection, through supporting collagen production, to reducing discoloration and brightening the complexion. Its regular use allows not only to slow down the aging process, but also to significantly improve the condition of the skin after just a few weeks of treatment.

Thanks to advances in formulation technology, stable and well-tolerated forms of vitamin C are now available (such as 3-O-Ethyl Ascorbic Acid or Magnesium Ascorbyl Phosphate), which can be used even on sensitive and problematic skin. The effectiveness of vitamin C has been confirmed by numerous clinical studies, and its versatility means that it is used in the care of mature, vascular, oily or acne-prone skin.

The key to success is the right choice of concentration, the right form of the ingredient and the systematic application in combination with sun protection. Vitamin C cosmetics - such as serum-ampoules and the Hello Papaja line from Orientana - are a great way for daily, effective and safe skin care with visible results.

HOW TO CARE FOR GREY HAIR

Hair graying is a physiological process that occurs with age and is associated with the progressive loss of melanocytes in the hair follicle. These cells are responsible for the production of melanin - a pigment that gives hair its natural color. Reduced melanocyte activity and finally their complete degeneration causes gray hair to appear - devoid of pigment. This process can begin after the age of 30 and is determined both genetically and environmentally. Studies indicate that gray hair differs not only in color, but also in structure and physicochemical properties. Hair without melanin has higher porosity, is rougher to the touch, is more brittle and tends to dry out. In addition, melanin also has a protective function against UV radiation - its lack increases the sensitivity of hair to external factors, including solar radiation, air pollution and aggressive chemical ingredients contained in care products and hair dyes. From a scientific point of view, gray hair care should be subject to care that limits lipid oxidation, protects against oxidative stress and is intensively moisturized. Studies published in the Journal of Cosmetic Dermatology (2020) have shown that the use of antioxidants such as vitamin E (tocopherol), green tea extract (Camellia sinensis) or coenzyme Q10 can improve the structural integrity of gray hair and reduce its brittleness. It is also worth paying attention to film-forming ingredients, such as plant proteins, which create a protective layer on the hair surface, preventing moisture loss. Another important aspect of grey hair care is eliminating unwanted yellow reflections, which often appear as a result of keratin oxidation or the deposition of metal impurities from water. Products containing purple or blue correcting pigments (e.g. dark purple CI 60730 or blue CI 42090) can effectively neutralize yellowish tones and restore a cool, silver tone to grey hair. Thermal protection also plays a key role – grey hair is more susceptible to damage caused by heat styling. Ingredients such as hydrolysed keratin, panthenol or oils rich in unsaturated fatty acids (e.g. grape seed oil, tsubaki oil) have a protective effect against high temperatures and support the reconstruction of weakened hair structure. In light of available scientific data, gray hair should be cared for in a multi-stage and holistic manner – care should include cleansing, color protection, moisturizing, and rebuilding the keratin structure. Regular use of cosmetics containing active substances with proven effects can significantly improve the appearance, elasticity, and resistance of gray hair to external factors. gray hair - Moisturizing and nourishing Gray hair, due to the lack of melanin, has different physical and chemical properties than pigmented hair. Melanin not only gives hair color, but also affects its structure and moisture level. With its loss, the hair's hydrolipid balance is disturbed, which results in increased dryness, brittleness and loss of elasticity. The structure of the gray hair cortex becomes more porous, which facilitates water loss and makes it more difficult for the hair to retain moisture within its structure. According to research published in the International Journal of Trichology (2018), gray hair is characterized by a lower content of internal lipids and a higher degree of keratin oxidation. These changes translate into reduced hair elasticity and greater susceptibility to mechanical and thermal damage. Therefore, a key element of gray hair care is to provide it with moisturizing and nourishing substances that will compensate for the loss of the natural protective barrier. In daily care, it is worth reaching for conditioners and masks containing humectants - water-binding substances such as glycerin, hyaluronic acid, betaine or aloe (Aloe barbadensis). They work by attracting moisture from the environment and retaining it inside the hair. Humectants should be used in combination with emollients – occlusive ingredients that create a layer on the hair surface that prevents water from evaporating. Effective emollients include vegetable oils (e.g. avocado oil, olive oil, jojoba oil), shea butter, fatty alcohols (cetyl alcohol, cetearyl alcohol). Hydrolyzed proteins – such as oats or wheat – also play an important role in hair nutrition. They have a regenerative effect on damaged parts of the hair shaft, strengthen its structure and improve its elasticity. A study conducted by a group of researchers from the University of São Paulo (2021) showed that regular use of protein masks increases hair resistance to breakage by up to 40%, which is particularly important in the case of weakened and gray hair. It is also worth paying attention to the pH of the products you use. Gray hair, like the scalp, responds best to products with a slightly acidic pH (pH 4.5–5.5), which closes the hair cuticles, smoothes its surface and prevents further moisture loss. Products with an alkaline pH can lead to increased porosity and aggravate the problem of dryness. Gray hair that is systematically cared for with appropriately selected cosmetic formulas and protected from the effects of external factors is the key to maintaining the healthy appearance, softness and elasticity of hair without pigment. UV protection Gray hair, due to the loss of melanin, loses its natural protective barrier against the harmful effects of ultraviolet (UV) radiation. Melanin plays an important photoprotective role, absorbing and scattering solar radiation, thus protecting both the hair shaft and hair follicle cells from oxidative damage. In the case of hair without pigment, this protection is significantly weakened, which leads to accelerated aging of the hair fiber. UV radiation – particularly UVA and UVB radiation – causes photodegradation of keratin proteins, lipid oxidation, and damage to the cortical structure of the hair. Studies by Robbins and Kelly ( Journal of the Society of Cosmetic Chemists , 1991) have shown that exposure of hair to UV radiation leads to a significant loss of its mechanical integrity, and gray hair loses elasticity and becomes more brittle than naturally dark hair. Moreover, prolonged sun exposure results in a change in hair color to a yellowish or yellow-brown shade, which deteriorates its aesthetic appearance. Gray hair can be protected from UV radiation with cosmetics enriched with antioxidants, which neutralize free radicals generated by solar radiation. Effective antioxidants include tocopherol (vitamin E), ascorbic acid (vitamin C), green tea polyphenols and extracts from adaptogenic plants such as Rhodiola rosea or Withania somnifera. Their presence enhances the photoprotective effect and supports the regeneration of damaged hair structure. In conditions of intense sunlight – especially in summer and during exposure to the sun in high mountains or by the sea – it is recommended that gray hair be physically protected, in the form of headgear. Wearing hats, caps or scarves protects not only the hair shaft itself, but also the scalp, which in the case of people with thinning hair is also exposed to photodamage. Avoiding high temperatures Gray hair, devoid of melanin, is particularly susceptible to damage caused by high temperatures. Melanin not only gives hair its color, but also affects its physicochemical properties, including resistance to thermal stress. Grey hair, due to its structure, has a thinner lipid layer, is more porous and less elastic, which makes it more susceptible to drying, breaking and split ends. Research published in the Journal of Cosmetic Science (2004) showed that exposure of hair to temperatures exceeding 150°C leads to degradation of keratin proteins, particularly in the cortex, as well as to irreversible changes in the structure of intercellular lipids. Gray hair, being more brittle and dry, undergoes these processes more quickly and intensively. Frequent use of straighteners, curling irons or hot air from a hair dryer can lead to a significant deterioration of the hair's condition - a decrease in its mechanical strength, dullness and loss of natural smoothness. To minimize the effects of heat, it is recommended to limit the use of styling tools based on high temperatures. Whenever possible, it is worth choosing cold styling methods or using devices with temperature control, setting them at a level not exceeding 130-150 ° C. Laboratory studies show that temperatures above 180 ° C cause keratin denaturation and damage to the hair surface after just one use of a straightener. Gray hair should be protected from heat by using heat protectants. They contain ingredients that create a thin, protective coating on the hair surface that limits heat conduction and reduces water evaporation from the hair. The most commonly used thermoprotective substances include silicones (e.g. dimethicone, amodimethicone), polymers (e.g. polyquaternium-55, hydroxypropyltrimonium hydrolyzed wheat protein). We recommend natural ingredients such as natural oils rich in unsaturated fatty acids, such as rice oil, coconut oil or grape seed oil. In a study by Jung et al. (2011), it was shown that using a product containing dimethicone before using a straightener significantly reduced moisture loss and limited damage to the cuticular layer. The protection was even more effective when the product also contained plant proteins, which penetrate the hair and support its reconstruction. It is also worth remembering that hair is most susceptible to overheating when it is still damp. Wet styling – especially straightening or curling – leads to rapid evaporation of water, which can cause the so-called "bubble hair" effect, i.e. the formation of microscopic air bubbles in the hair structure, leading to its breakage. For this reason, you should always dry your hair thoroughly before using heating devices, using a cooler airflow and thermal protection. gray hair - Diet and supplementation The condition of hair, including its pigmentation, elasticity and resistance to damage, is closely linked to general health and diet. Graying of hair, although primarily genetically determined and related to the aging process, can be accelerated by deficiencies of certain vitamins and microelements. The scientific literature increasingly emphasizes the role of nutrients in maintaining the health of hair follicles and potentially delaying depigmentation processes. B vitamins, especially vitamin B12 (cobalamin), play a key role in the metabolism of hair follicle cells. B12 deficiency can lead to megaloblastic anemia, a symptom of which is premature graying. A study published in the International Journal of Trichology (2013) found significantly lower levels of vitamin B12 and folate (B9) in young people with premature graying compared to the control group. Other B vitamins, such as B6 (pyridoxine) and B7 (biotin), support keratin synthesis and scalp health. Minerals also play an important role in maintaining hair pigmentation. Copper is an essential cofactor for tyrosinase, an enzyme responsible for melanin synthesis. Its deficiency can disrupt this process and lead to hair loss. Zinc, on the other hand, is involved in cell division and supports hair growth. A review of the literature published in Dermatology and Therapy (2020) indicated that both zinc and copper deficiency can affect hair quality and pigmentation, although further clinical studies are needed to determine the exact mechanisms behind these relationships. In addition to vitamins and minerals, bioactive compounds with antioxidant effects, such as polyphenols, flavonoids and plant adaptogens, are gaining increasing interest. Antioxidants neutralize free radicals that can contribute to oxidative stress in the hair follicle – considered one of the factors leading to graying. Extracts from green tea, ginseng (Panax ginseng), turmeric (Curcuma longa) and ashwagandha (Withania somnifera) have been shown to have a beneficial effect on scalp health and the hair growth cycle, and some of them can also support pigment retention. It is worth remembering that supplementation should always be tailored individually, preferably after consulting a doctor or dietitian and after performing laboratory tests. An excess of some ingredients (e.g. zinc or selenium) can be harmful, so supplements should not be used without control. The most effective and safest is to include natural sources of nutrients in the diet: fish, eggs, nuts, seeds, leafy vegetables, whole grains and legumes. gray hair and stress Stress, especially chronic stress, plays a significant role in accelerating the aging process, including hair graying. One of the key biological mechanisms through which stress affects hair follicles is oxidative stress – a state of imbalance between the production of free radicals and the body's ability to neutralize them with antioxidants. Free radicals can damage melanocyte cells responsible for melanin production, which leads to premature hair depigmentation. Research conducted by scientists from Harvard University (Zhang et al., Nature , 2020) has shown a direct link between stress and melanocyte loss. In a mouse model, severe stress was shown to activate the sympathetic nervous system, which leads to the release of norepinephrine within the hair follicle. This substance induces excessive activity of melanocyte stem cells, which then become exhausted, resulting in permanent pigment loss. Although this mechanism has been thoroughly studied in animals, it suggests that stress in humans may also accelerate the graying process through similar biological pathways. Reducing psychological and physiological stress can therefore be an important element in the care of gray hair, not only from an aesthetic but also a biological perspective. Proven methods of reducing stress include breathing techniques, mindfulness meditation, yoga, and regular physical activity. A study published in JAMA Internal Medicine (2014) showed that daily practice of mindfulness meditation lowers cortisol levels – the stress hormone – and improves emotional balance and sleep quality, which can have a positive effect on the condition of the skin and hair. Physical activity also plays a significant role in neutralizing the effects of stress. Regular aerobic exercise, such as brisk walking, swimming, or cycling, increases endorphin production and supports the body's detoxification processes, reducing systemic inflammation and oxidative stress. Long-term benefits of physical activity include improved microcirculation in the scalp, which can support hair follicle nourishment and proper functioning. It is also worth emphasizing the role of adaptogens – plant substances that support the body's resistance to stress. Extracts from plants such as Rhodiola rosea, Withania somnifera (ashwagandha) or Eleutherococcus senticosus can affect the HPA axis (hypothalamus-pituitary-adrenal glands), regulating cortisol levels and strengthening resistance to mental stress. Some of these substances also have antioxidant effects, which makes them an interesting addition to graying prevention. How to protect your hair from premature graying To delay the process of premature graying of hair, it is worth implementing appropriate care. Ayurvedic Amla and Bhringraj hair oil will work great here. This is a product based on traditional recipes of Ayurvedic medicine. It contains extracts of amla fruit (Emblica officinalis) and bhringraj herbs (Eclipta alba), which are valued for their properties of strengthening hair, stimulating its growth and preventing premature graying. Regular use of this oil nourishes the scalp, strengthens hair follicles and can delay the process of pigmentation loss. Amla (Emblica officinalis) – also known as Indian gooseberry – protects hair from premature graying, as confirmed by both traditional Ayurvedic medicine and a growing body of scientific research. Some studies on animal and cell models have shown that compounds contained in amla can stimulate the activity of tyrosinase – an enzyme crucial for melanin synthesis. This suggests the potential of amla to slow down pigment loss. Amla is exceptionally rich in vitamin C and polyphenols (e.g. emblicanins A and B), which have strong antioxidant effects. They help neutralize free radicals that damage melanocytes – cells responsible for producing melanin (hair pigment). How to use Ayurvedic Amla Bhringraj Oil? Massage a small amount of the oil into the scalp and spread over the entire length of the hair. Leave it for a few hours or overnight, then wash your hair with a gentle shampoo. Regular use, e.g. 2-3 times a week, can bring the best results in the form of strengthened, healthy hair with preserved natural pigmentation. We now know that gray hair requires a holistic approach that considers both external care methods and internal health factors. Evidence-based strategies can help maintain the health and aesthetics of gray hair.

KOKUM BUTTER – THE MOST KNOWN SKIN CARE BUTTER IN INDIA

Of the butters found in cosmetics, you probably associate shea butter the most, which is commonly used in cosmetics. In Orientana natural cosmetics, we very often use kokum butter. It is obtained from the seeds of kokam - a Garcinia Indica plant growing in India. Most often in the mountainous areas of the Indian coast - around Bombay and the Indian state of Goa. These seeds are very similar to the closely related mangosteen and are often confused with it. Kokum butter is a very healthy, ecological raw material due to its cultivation without the use of chemicals, sprays and fertilizers. It is also one of the hardest vegetable fats, which is why it is often used to produce lipsticks and lip balms. It is also an excellent base for body creams and balms and other care cosmetics. And all this for a reason! It absorbs very quickly and does not clog pores! In this entry, we will describe how many valuable properties kokum butter has. USE OF GARCINIA INDICA FRUITS IN THE FOOD INDUSTRY The fruit is purple in color and is often used to color and flavor dishes.

IS THERE A HENNA FOR GRAY HAIR?

Henna for gray hair is not a challenge at all! Read and try it yourself. Dyeing gray hair with henna is becoming an increasingly popular solution for people looking for natural, safe and permanent coloring methods. Henna, a powder obtained from the leaves of the defenseless Lawsonia inermis , not only gives hair a beautiful color, but also strengthens its structure. However, the process of applying henna to gray hair requires special attention and proper preparation to achieve optimal results. Below you will find a comprehensive step-by-step guide on how to apply henna to gray hair. Why is henna for GREY HAIR the perfect solution? Henna for gray hair is a wonderful natural cosmetic. It changes hair color, gives hair a beautiful shine, strengthens hair follicles, cares for the scalp and reduces scalp oiliness. A natural alternative to chemical paints Henna is a great option for those who want to avoid the chemicals found in traditional hair dyes. Gray hair, due to its specific structure, can be more sensitive to harsh chemicals, so henna is a gentle yet effective choice. Hair durability and care In addition to its coloring properties, henna strengthens hair, improves its texture and gives it a healthy shine. Its natural compounds act as a conditioner, reducing breakage and making hair soft. WILL HENNA DYE GRAY HAIR? WHEN DOES GREYING BEGIN AND WHAT DOES IT LOOK LIKE? Henna is not always able to completely cover grey hair, because grey hair has a different structure and properties compared to pigmented hair. In people of Caucasian descent, greying usually begins around the age of 35. People of Asian descent start greying from the age of 40, and in black people the first grey hair appears around the age of 45 . About 50% of the population has at least 50% grey hair by the age of 50, known as the "50-50-50 rule" On average, a person loses about 10-20% of melanocytes (cells responsible for hair pigmentation) every decade after the age of 30. The rate of graying varies. Faster in people with genetic predisposition (early graying). Slower in people who lead a healthy lifestyle and have low stress levels. There are no significant differences between men and women in the age at which gray hair first appears. Men tend to notice graying at the temples and beard earlier than in other areas. Women are more likely to experience graying evenly over the entire head. Factors that accelerate graying The strongest factor influencing age and the rate of graying is genetics. If people in our family gray quickly, we have a high percentage chance that we will also gray hair quite early. Scientific studies suggest that long-term stress can also damage melanocyte cells, leading to earlier graying. Oxidative stress, caused by free radicals, also contributes to pigment loss. Lifestyle is very important. Smoking doubles the risk of premature graying. An improper diet, poor in B vitamins (e.g. B12), iron or copper, can accelerate the graying process. Autoimmune diseases (e.g. vitiligo, alopecia areata) and vitamin deficiencies can lead to loss of hair pigment. For such people, henna for gray hair is a perfect natural solution. WHAT DOES GREY HAIR MEAN? Lack of natural pigment in gray hair Gray hair lacks melanin, the natural pigment responsible for hair color. Henna works by binding to the keratin in the hair and enhancing its color, but in the absence of melanin, this process is less effective. Gray hair is more "transparent" compared to pigmented hair, which can cause henna to not provide an intense color. Changed structure of gray hair Thicker hair cuticle: Gray hair often has a thicker, more compact cuticle, making it harder for the henna dye to penetrate. More porosity: Gray hair, on the other hand, can be more porous, which can cause the henna to not spread evenly, leading to uneven color. HOW HENNA WORKS ON GREY HAIR Henna reads Mahogany Red works as a translucent dye that adds color by layering over the natural hair tone. On very light gray hair, henna may give a more orange or copper tone instead of full coverage. Pigmented hair forms the base for the chosen henna color, while gray hair requires an additional step to achieve a deeper color. The inability of henna to turn a darker color is NOT A PROBLEM Natural henna does not contain chemicals or other dyes (apart from red) that could penetrate deeply into the hair and create a darker or more saturated color. In the case of gray hair, henna can only give a copper shade, which often seems too light or insufficiently covering. Mixtures of natural henna with the addition of indigo and Ayurvedic herbs such as Dark Brown Henna , Caramel Brown Henna or Walnut Henna . Henna coloring mixtures can leave a green sheen on gray hair. It is necessary to dye in two stages. First, pure henna Mahogany Red is dyed to give the hair an orange or copper shade. Then a mixture of henna and indigo is used to obtain a deeper color. hennA for gray hair - How to increase effectiveness ? It is necessary to dye in two stages . First red henna, then a mixture with indigo for better coverage. Longer holding time is required: henna on gray hair. Gray hair may require 4-6 hours for the dye to fully absorb. It is good to create an acidic environment for henna. Adding lemon juice or vinegar to the mixture improves the release of the dye. THE PROCESS OF HEATING GREY HAIR Henna for grey hair requires special attention. We need to buy two packages of henna - red and the color we want to achieve. Before applying henna, the hair should be properly prepared. Wash your hair with a shampoo without SLS and SLES to gently cleanse the hair. Do not use conditioner because the conditioner can create a barrier that will make it difficult for the henna to penetrate the hair. Comb your hair well. Make sure the hair is free of tangles. Preparation of the mixture Proportions and ingredients : Use the appropriate amount of henna depending on the length of your hair (e.g. 50-100 g for medium length hair). Mix red henna (pure) with warm water (approximately 50-60°C) until you obtain a smooth, thick paste. Add a little acidic ingredient (e.g. lemon juice, apple cider vinegar) to better release the dye. Henna application Skin and clothing protection : Apply Vaseline or oil along the hairline to avoid staining the skin. Wear gloves. You can protect your clothes, but henna stains will come out in a regular machine wash. Application : Divide your hair into sections and apply the paste from roots to ends, making sure all gray hairs are thoroughly covered. After application, wrap your hair in plastic wrap or wear a plastic cap to maintain moisture. Put a hat on your foil-protected hair - henna works better when warm. Holding time : Henna for gray hair stays on the head for 2-3 hours. Gray hair may require longer time to achieve intense color. Rinsing off henna Rinse your hair with lukewarm water without shampoo. If necessary, gently remove any remaining paste with your fingers. Avoid shampooing for the next 24-48 hours to allow the dye to set. HENNA FOR GREY HAIR - SECOND APPLICATION We already have hair dyed with pure red henna. It is probably not the color you want, so the next day you can immediately apply Henna coloring in the chosen shade. Proportions and ingredients : Use the appropriate amount of henna mixture depending on the length of your hair (e.g. 50-100 g for medium length hair). Mix henna of your chosen colour with warm water (approximately 50-60°C) until you obtain a smooth, thick paste. Apply to hair Rinse without shampoo. Additional tips for dyeing gray hair with henna include regularity of application - henna does not wash off the hair, but regrowth will be visible. Repeat dyeing every 4-6 weeks. Summary Henna for gray hair is a natural and safe alternative to chemical dyes. With proper preparation, selection of the mixture and following the right steps, you can achieve a lasting, beautiful color and healthy and strong hair. This process, although more time-consuming than chemical dyeing, brings benefits to both the aesthetics and condition of the hair.
