The skin's hydrolipid barrier – how does it work and how to rebuild it?
Your skin is exposed to external factors every day – pollution, UV radiation, temperature changes, and dry indoor air. The skin's hydrolipid barrier serves as a natural protective shield, protecting the epidermis from dehydration, irritation, and loss of elasticity. When it functions properly, skin is soft, smooth, and resistant to damage. However, when it becomes weakened, problems such as dryness, roughness, hypersensitivity, and even inflammation quickly arise. Awareness of the role of the hydrolipid barrier is key to effective skincare and healthy skin. Therefore, in this article, we explain: what is the hydrolipid barrier and what function does it perform, what damages it and what symptoms it causes, what active ingredients and cosmetics support its regeneration, how natural care and appropriate products, e.g. with ceramides and vegetable oils, help rebuild the skin barrier. Thanks to this knowledge, you will learn how to easily improve the condition of your skin and enjoy its healthy, radiant appearance. What is the skin's hydrolipid barrier? The hydrolipid barrier is a natural protective layer found on the skin's surface and plays a key role in maintaining its health. It consists of a layer of lipids (fats), water, and dead skin cells. It can be compared to a "protective wall" that protects the skin's interior from water loss and the harmful effects of external factors. When the barrier functions properly, it retains moisture in the epidermis and protects it from pollutants, allergens, microorganisms, and UV radiation. This leaves the skin supple, smooth, and less susceptible to irritation. However, if the hydrolipid barrier is compromised—for example, by the use of harsh detergents, frequent exfoliation, or unfavorable environmental conditions—the skin loses its natural protection, becoming dry, sensitive, and susceptible to damage. That's why it's so important to understand how the hydrolipid barrier works and which active ingredients help rebuild it. Conscious skincare can strengthen the skin's natural defenses and prevent many problems, including excessive dryness, irritation, and premature aging. Composition of the hydrolipid barrier – lipids, NMF and keratinocytes The skin's hydrolipid barrier isn't a uniform layer—it's composed of various components that collectively contribute to its tightness and protective function. It's the balance between lipids, natural moisturizing factor (NMF), and keratinocytes that determines whether the skin will be healthy, resilient, and well-hydrated. Lipids – natural skin fats Lipids act as a "mortar" that holds the cells of the stratum corneum together. They include: ceramides – responsible for maintaining the integrity of the barrier, fatty acids – enhance protection against TEWL (water loss), cholesterol – stabilizes the structure of the epidermis. Thanks to them, the skin remains elastic, resistant to irritation and less susceptible to dryness. NMF – natural moisturizing factor NMF (Natural Moisturizing Factor) is a complex of substances that bind water in the epidermis. Its components include: hyaluronic acid, amino acids, urea, lactates. Thanks to them, the skin does not lose moisture and remains soft and smooth. Keratinocytes – the “bricks” in the skin structure Keratinocytes are the primary cells of the epidermis that produce keratin , a protein that gives skin its strength. They form "bricks" that, together with lipids ("mortar"), create a tight barrier protecting the skin from external factors. Functions of the hydrolipid barrier for the skin The hydrolipid barrier plays not only a protective role but also a regulating and moisturizing one. It helps the skin maintain its health, elasticity, and youthful appearance. Protection against moisture loss (TEWL) One of the key functions of the hydrolipid barrier is to prevent transepidermal water loss (TEWL) . Thanks to lipids and NMF, the skin retains water within the epidermis, protecting it from dryness, roughness, and loss of elasticity. Protection against external factors The barrier acts as a shield, protecting against: environmental pollution, allergens, UV radiation, microorganisms (bacteria, fungi, viruses). This reduces the risk of infection and inflammation. Regulating the skin microbiome Billions of microorganisms live on the skin's surface, making up the skin's microbiome . A healthy hydrolipid barrier supports a balance of "good bacteria" that protect against the growth of pathogenic microorganisms. Homeostasis and cell renewal The hydrolipid barrier helps maintain the skin's metabolic balance. It regulates processes such as: cell renewal, healing of microdamages, maintaining the proper pH of the skin. As a result, the skin looks healthy, remains firm and ages slower. Symptoms of a damaged hydrolipid barrier When the skin's hydrolipid barrier is weakened, the body immediately signals this. Symptoms can range from mild dryness to chronic inflammation. Ignoring these symptoms leads to worsening skin condition and impeding regeneration. Dryness and tightness The skin loses its ability to retain water, which is manifested by: dryness, roughness, unpleasant feeling of tension after washing. Irritations and hypersensitivity A weakened barrier is more susceptible to: redness, itch, burning after applying cosmetics. Skin hyperreactivity often occurs even to gentle care products. Tendency to inflammation A damaged barrier promotes the development of: acne, eczema, atopic dermatitis (AD). Bacteria and allergens penetrate the epidermis more easily, which intensifies skin symptoms. Microbiome imbalance A disturbed protective layer leads to a reduction in the number of "good bacteria" and the development of pathogenic microorganisms, which further worsens the condition of the skin. How to rebuild the hydrolipid barrier? (step-by-step care) Rebuilding the hydrolipid barrier requires patience and carefully selected cosmetics. Gentle cleansing formulas, moisturizing active ingredients, and products that strengthen the skin's lipid layer are key. Step 1. Gentle cleansing Aggressive detergents and strong cleansers (e.g., those containing SLS or alcohol) damage the skin's protective barrier. Therefore, choose products with gentle cleansing agents. Recommended from Orientana: Gentle Date and Inulin Facial Wash Gel – effectively removes impurities, and thanks to inulin and date extract, it supports the balance of the skin microbiome. Step 2. Toning and moisturizing Restoring the skin's proper pH and hydration is the basis for barrier regeneration. Recommended from Orientana : Tonic-essence Date, Gluconolactone, Proteins – combines the effects of tonic and essence, gently exfoliates, strengthens the hydrolipid barrier and intensively moisturizes. Step 3. Serum rebuilding the hydrolipid barrier This stage delivers active ingredients in concentrated form. The following work best: ceramides , hyaluronic acid , niacinamide . Recommended from Orientana : Advanced Skin Repair Serum Reishi Cerafluid® – contains liquid ceramides that fill “gaps” in the lipid barrier. Hydration serum-ampoule with ashwagandha – rich in hyaluronic acid and natural extracts, intensively binds water in the epidermis. Ashwagandha + CICA + Niacinamide Serum – supports skin regeneration, has anti-inflammatory properties and strengthens protection against oxidative stress. Step 4. Lipid layer rebuilding cream The cream should create a protective film that prevents water loss and protects against external factors. Recommended from Orientana : Reishi Day Cream / Reishi Night Cream – intensively nourish and rebuild the protective barrier. Kali Musli Day and Night Cream – contains the innovative ingredient CARESOFT™, which reduces skin reactivity and accelerates the regeneration of the hydrolipid barrier. Comfortable nourishing cream Hello Daktyl - ideal for dry and sensitive skin, strengthens the lipid layer and soothes irritations. Sandalwood and Turmeric Balance Cream - perfectly nourishes, regulates and strengthens the hydrolipid barrier. Step 5. UV protection Sun exposure is one of the main factors damaging the skin's barrier. Daily use of a sunscreen is essential for skincare to support regeneration. The most important ingredients supporting the hydrolipid barrier Regenerating and maintaining the proper function of the hydrolipid barrier requires the provision of appropriate active ingredients. These ingredients rebuild lipids, bind water in the epidermis, and strengthen the skin's resistance to external factors. Ceramides - the foundation of a healthy barrier Ceramides are lipids naturally present in the skin that act as a "cement" that holds epidermal cells together. Their deficiency leads to dryness and hypersensitivity. When supplied in cosmetics, they fill gaps in the lipid barrier, accelerating its reconstruction. Orientana recommends: Advanced Skin Repair Serum Reishi Cerafluid® - liquid ceramides that effectively strengthen the protective barrier and improve skin elasticity. Natural vegetable oils - lipid restoration Vegetable oils are a source of fatty acids, which regenerate the lipid layer and protect the skin from water loss. They enhance its elasticity and additionally provide vitamins and antioxidants. Orientana recommends: Ayurvedic Ashwagandha face cream or Sandalwood and Turmeric Cream - rich in natural plant oils that nourish and rebuild the skin. Hyaluronic acid and NMF - intense hydration Hyaluronic acid and other components of the natural moisturizing factor (NMF), such as amino acids and urea, retain water in the epidermis and protect against excessive moisture loss. This makes the skin softer, smoother, and more supple. Orientana recommends: Hydration Serum Ampoule with Ashwagandha – intensely moisturizes and regenerates skin, reducing tightness. Hydro Tremella Elixir Serum with Exosomes – provides long-lasting hydration and regeneration. CARESOFT™ - an innovative soothing and regenerating ingredient CARESOFT™ is a bioactive Curculigo orchioides root extract that reduces skin reactivity and supports its regeneration. Studies show that it reduces irritation by up to 65% and accelerates the regeneration of the hydrolipid barrier by 20%.

Ceramide and Reishi Serum – the key to strong skin
Have you heard about Ceramide Serum and Reishi? It's a cosmic combination! Do you know why ceramides are crucial for skin health? I'll try to explain it to you. CERAMIDES - WHAT ARE THEY? Ceramides , natural lipids, are an essential part of our skin, where they play an important role in its hydration and elasticity. These key ingredients are found in Orientana's highly rated serum , where they create a protective barrier for the skin. Ceramides are bioactive lipids belonging to the sphingolipid group, which play a key role in maintaining the integrity and function of the epidermal barrier. They constitute about 50% of the lipids of the stratum corneum, where – alongside cholesterol and free fatty acids – they create an ordered lipid structure responsible for limiting transepidermal water loss (TEWL) and protecting the skin from external factors. Ceramides act as an “intercellular cement”, bonding corneocytes and ensuring proper tightness of the epidermis. Keratinocytes are the builders of the skin Keratinocytes are directly related to ceramides , because they are the ones that produce ceramides – key lipids responsible for the proper functioning of the epidermal barrier. They can be described as a ceramide factory. Keratinocytes constitute the main population of epidermal cells (epidermis), accounting for about 90–95% of all its cells. They are specialized epithelial cells that play a key role in the formation, maintenance and regeneration of the skin's protective barrier. Their primary function is the production of keratin – a structural protein that provides the skin with mechanical strength and resistance to external factors. The life cycle of keratinocytes begins in the basal layer (stratum basale), where these cells proliferate intensively. Then they move to the surface of the epidermis, passing through successive layers: the spinous layer (stratum spinosum), the granular layer (stratum granulosum), and finally the stratum corneum (stratum corneum). In this process, keratinocytes undergo gradual terminal differentiation, losing their cell nuclei and transforming into corneocytes – “dead” horny cells that form the outer, protective covering of the skin. The entire cycle from proliferation to desquamation takes about 28 days in a healthy adult. During their migration to the surface, keratinocytes synthesize not only keratin, but also a number of structural proteins and enzymes (e.g. filaggrin, loricrin, involucrin), which form the so-called corneocyte envelope – an integral part of the physical skin barrier. At the same time, they produce intercellular lipids, such as ceramides, cholesterol and free fatty acids, which cement cells in the stratum corneum, ensuring tightness and limiting transepidermal water loss (TEWL). Keratinocytes also play an important immunological role. In response to mechanical damage, UV radiation or the presence of pathogens, they release cytokines, chemokines and antimicrobial peptides (including defensins and cathelicidins), activating a local inflammatory response and communicating with immune system cells. As a result, they are not only a physical barrier, but also an active participant in the skin's immunological defense. Mechanisms of action of ceramides at the cellular level From the perspective of skin biology, ceramides not only play a structural role, but also demonstrate signaling activity. They participate in the processes of keratinocyte differentiation and regulation of the inflammatory response. Studies have shown that their deficiency leads to skin barrier dysfunction, which is manifested by increased TEWL, dryness, itching, and increased susceptibility to irritants and allergens. Reduced levels of ceramides are observed in dermatological diseases such as atopic dermatitis, psoriasis, and eczema. Ceramides in cosmetology and aesthetic dermatology The use of ceramides in dermocosmetic preparations is aimed at rebuilding the lipid barrier and restoring epidermal homeostasis. These ingredients demonstrate high biocompatibility, which is why they can also be used in products intended for sensitive and reactive skin. A study conducted by Sugarman et al. (2005) showed that the use of an emulsion containing ceramides type 1, 3 and 6-II for 4 weeks significantly reduced TEWL and improved skin hydration parameters in a group of patients with AD. Ceramides and reishi serum - protection of the hydrolipid barrier The proper condition of the skin's hydrolipid barrier is extremely important to protect it from water loss and protect it from harmful external factors, such as free radicals, toxins, environmental pollution, and bacteria. Have you wondered how to protect this barrier? Do you know what the symptoms of its destruction are? Symptoms of damage to this barrier are usually easy to spot. The skin becomes dry, rough and flaky, and there is often a feeling of tightness, burning or itching. There may also be redness and hyperreactivity – the skin reacts with irritation even to mild cosmetics or water. In more advanced cases, there are micro-cracks in the epidermis, inflammation and even severe symptoms of dermatological diseases such as atopic dermatitis or rosacea. Ceramides and reishi serum - The role of ceramides in skin care Ceramides are an invaluable ingredient in the process of rebuilding the skin barrier. Their ability to increase keratinocyte cell adhesion leads to stronger cell bonding, which results in the creation of a strong skin structure. Therefore, ceramides are irreplaceable in the care of dry, sensitive skin, and as support during retinoid or acid treatment. That is why we recommend using Ceramide and Reishi Serum during the day and retinol cosmetics at night. With age, a physiological decrease in ceramide synthesis is observed in the epidermis, which results in a weakening of the barrier function and an increase in the symptoms of dryness, roughness and loss of elasticity. Cosmetics enriched with ceramides can compensate for these deficiencies, supporting regenerative processes and improving the overall condition of mature skin. Thanks to this, ceramides are an important element of a care strategy aimed at rebuilding and protecting the skin barrier. Ceramides and reishi serum - the role of adaptogen in skin care Reishi (Ganoderma lucidum), also known as Ganoderma lucidum, is a mushroom with unique adaptogenic properties that has been used in Chinese medicine for over 2,000 years. Its effects include immune support, anti-inflammatory action and modulation of oxidative stress – factors that are also key to skin health. In recent years, reishi has gained popularity as a cosmetic ingredient with a broad spectrum of biological action. Orientana uses this ingredient in a series of facial cosmetics. Reishi supports the balance of the skin microbiome and limits excessive immune response, which may be important in the context of atopic, acne or psoriasis skin care. Regular use of cosmetics with its content contributes to improving the elasticity, hydration and overall resistance of the skin to external stressors. Additionally, thanks to the presence of natural antioxidants, reishi helps protect against photoaging and has a rejuvenating effect on the skin. How to choose cosmetics with ceramides? Ceramide Reishi Serum demonstrates exceptional biocompatibility with the skin, enabling deep penetration of ceramide NP into the epidermis. As a result, it works very effectively on rebuilding the hydrolipid barrier, improves skin elasticity and firmness, and also reduces the visibility of wrinkles. When choosing cosmetics with ceramides, it is important to pay attention to their composition and biocompatibility with ceramides naturally occurring in the skin. Products such as Orientana Ceramides Reishi serum are pioneers in skin care, offering the highest quality and effectiveness in rebuilding the skin barrier. Orientana is a brand that guarantees the quality and effectiveness of its products, using the latest scientific achievements in dermatology and cosmetology, using natural plant ingredients sourced directly from ecologically clean regions of Asia. The right selection of cosmetics with ceramides is the key to healthy, firm and strong skin.
