While many people focus on creams, serums and masks, true skin beauty starts from the inside . The way we eat has a huge impact on the appearance, condition and health of our skin. More and more research confirms that superfoods – natural products with an exceptionally high content of nutrients – can act as an internal cosmetic, supporting the regeneration, radiance and youthfulness of the skin. What superfoods are worth including in your daily diet?
Diet and skin – why is it so important?
The skin is the largest organ in our body – its surface area in an adult is as much as 1.5–2 m² , and its mass is about 16% of the total body mass . It is the first to react to vitamin, mineral and antioxidant deficiencies. When the diet lacks key ingredients, the following may appear:
- dryness and flaking,
- increased susceptibility to irritation,
- inflammatory conditions (e.g. acne, atopic dermatitis),
- accelerated aging (loss of firmness can be observed after just 4 weeks of a diet low in healthy fats).
On the other hand, balanced nutrition provides the skin with “building blocks” for reconstruction, strengthens the hydrolipid barrier and protects against oxidative stress.
Superfood – what does that actually mean?
Superfood is a natural food, rich in vitamins, minerals, unsaturated fatty acids and antioxidants. It is usually distinguished from other products due to the high concentration of bioactive substances . Example? 100 g of acai berries contain 10 times more antioxidants than grapes. But it is worth remembering - superfoods are not a miracle cure, but an element of a holistic diet that supports the health and appearance of the skin.
Top 8 Superfoods for Healthy and Radiant Skin

Avocado
It contains as much as 15% healthy fats , as well as vitamins E and C - key in moisturizing and protecting the skin from aging. It works as a natural emollient from the inside.
Why does it work?
Avocado is a real nutritional bomb for the skin. It contains:
- healthy fats (omega-9 acids, mainly oleic acid),
- vitamins E and C – protecting cells against oxidative stress,
- lutein and zeaxanthin – supporting skin elasticity.
Numbers:
✔ 100 g avocado = ~15 g fat, 10 mg vitamin C, 2 mg vitamin E
How to eat?
Add it to salads, smoothies, sandwiches, or even make a chocolate spread (with cocoa and banana).
Berries (blueberries, acai, chokeberry)
Rich in anthocyanins and vitamin C. 100 g of blueberries provide about 9 mg of vitamin C and hundreds of ORAC units (a measure of antioxidant capacity).
Why do they work?
Berries are full of anthocyanins , powerful antioxidants that protect the skin from UV radiation and support collagen production. They also help regenerate damaged skin.
Numbers:
✔ Blueberries – ORAC: 4669
✔ Aronia – ORAC: ~16,000 (one of the highest results among fruits)
✔ Vitamin C: up to 20 mg per 100 g (chokeberry)
How to eat?
With yogurt, in oatmeal, smoothie, raw or in powdered form (acai).
Chia seeds and flax seeds
They contain as much as 18-23% omega-3 acids , which support the skin's lipid barrier and reduce inflammation. The fiber content also affects the body's detoxification.
Why do they work?
They are rich in:
- omega-3 acids (ALA),
- fiber, which improves digestion and body cleansing,
- lignans – plant compounds with antioxidant and hormonally regulating effects.
Numbers:
✔ 1 tablespoon of chia = 2.5 g omega-3
✔ Linseed – over 40% fat, of which 60% is ALA
How to eat?
Soaked in water/milk as a pudding, addition to porridge, smoothies or bread.
Carrots and sweet potatoes
Source of beta-carotene – 100 g of carrots contain as much as 8,300 μg of provitamin A , which supports cell renewal and improves skin tone.
Why do they work?
They contain beta-carotene , which is converted into vitamin A in the body, responsible for the regeneration of the epidermis, regulation of sebum secretion and protection against free radicals.
Numbers:
✔ 100 g carrots = 8300 µg beta-carotene
✔ 100g sweet potatoes = ~14,000 µg beta-carotene
How to eat?
It is best to add fat (e.g. olive oil) – it increases the absorption of carotenoids.
Green leafy vegetables (spinach, kale)
They contain iron, chlorophyll, magnesium and B vitamins. 100 g of spinach contains as much as 93% water , which helps hydrate skin cells.
Why do they work?
This is a mine:
- chlorophyll – cleanses the body and supports skin oxygenation,
- folic acid , B vitamins, magnesium and iron – support skin cell regeneration and collagen production.
Numbers:
✔ 100 g spinach = 2.7 mg iron, 194 µg folic acid
✔ Kale = up to 120 mg of vitamin C and 1.5 mg of manganese
How to eat?
Raw (salads), stewed, in cocktails or as oven-baked chips.
Tomatoes
Rich in lycopene – a powerful antioxidant that protects the DNA of skin cells. Cooked tomatoes have 2–3 times more absorbable lycopene than raw ones.
Why do they work?
They contain lycopene – an antioxidant from the carotenoid group, which protects the skin from the harmful effects of UV rays and slows down cell aging.
Numbers:
✔ 100g raw tomatoes = 2.5–4mg lycopene
✔ In processed products (e.g. passata) the content increases to 15 mg/100 g
How to eat?
Best slightly warmed (e.g. tomato sauce with olive oil), which increases the bioavailability of lycopene.
Walnuts and almonds
Source of zinc, selenium and vitamin E. 30 g of almonds covers 37% of the daily requirement of vitamin E , supporting protection against oxidative stress.
Why do they work?
Rich in:
- vitamin E – a strong antioxidant that protects skin lipids against oxidation,
- zinc and selenium – essential for proper skin healing and reducing inflammation.
Numbers:
✔ 30 g almonds = 7.3 mg vitamin E (49% RDA)
✔ 30g walnuts = 2.5g omega-3 (ALA)
How to eat?
A handful a day as a snack, an addition to muesli, salads or vegetable pastes.
Green tea

Contains EGCG – one of the most powerful polyphenols. It has anti-inflammatory effects, regulates sebum production and supports acne skin. Why does it work?
Contains polyphenols, especially EGCG (epigallocatechin gallate) – which:
- has anti-inflammatory and antibacterial properties,
- reduces redness and inflammation of the skin,
- protects against photoaging.
Numbers:
✔ A cup (250 ml) contains ~50–100 mg EGCG
✔ Studies show improvement in skin elasticity after 8 weeks of regular drinking
How to consume?
2–3 cups a day, preferably brewed at 70–80°C (not boiling water!) for maximum effectiveness.
Diet for specific skin needs
There is no one super diet for everyone – it is worth matching your choice of superfoods to your skin type:
- Acne skin: zinc, vitamin A, turmeric, green tea, pumpkin seeds.
- Dry and sensitive skin: avocado, olive oil, almonds, sea fish.
- Mature skin: products rich in collagen-forming vitamins (C, A), cocoa, berries, eggs and legumes.
Not just superfoods – but a whole lifestyle
Even the best superfoods won't help if you neglect the basics:
- Hydration: min. 1.5–2 liters of water per day ,
- Sleep: skin regeneration takes place mainly at night – sleep deprivation = slower regeneration,
- Avoiding stimulants: alcohol and cigarettes destroy collagen,
- Stress: Chronic stress increases cortisol levels, which worsens skin condition.
If you want radiant, healthy skin, take care of what ends up on your plate. Superfoods can be your daily, natural cosmetics – working from the inside. Their regular consumption supports the skin's protective barrier, delays the aging process and improves appearance without the need for Instagram filters.
Because true beauty is health that can be seen.
