Certain vitamins, minerals, and other micronutrients are known to contribute to healthy, beautiful skin. They can be found directly in food or in skin supplements.
The Importance of Antioxidants
Antioxidants are essential for beautiful, healthy skin, as they help combat oxidative stress. Cell oxidation is a natural process that plays a role in the aging of tissues, including the skin. This oxidation stems from an increase in free radicals, molecules produced in excess through smoking, stress, pollution, or excessive sun exposure, for example.
This accumulation creates an imbalance between the production of free radicals and the body's ability to neutralize them. This is where antioxidants come in, substances that reinforce the process of neutralizing free radicals.
Vitamin C
Vitamin C promotes the synthesis of collagen, the main protein component of the skin that contributes to its elasticity. It also has antioxidant properties, which combat skin aging. It is found, for example, in citrus fruits, blackcurrants, kiwis, cabbage, strawberries, fennel, spinach, and bell peppers, preferably eaten raw.
Vitamin E
Vitamin E is also often included in dietary supplements for skin health because it helps maintain skin elasticity while protecting the lipids in the superficial layer of the epidermis from oxidation. It is found in foods such as kiwis, mangoes, avocados, fennel, salsify, peas, spinach, hazelnuts, and almonds.
Zinc
Zinc plays a key role in strengthening the immune system. It contributes to the beauty of skin and hair thanks to its antioxidant properties. It also helps reduce excess sebum and renew skin cells. To benefit from it, consume organ meats and red meat, for example.
Omega-3
Fatty acids are essential for skin elasticity and suppleness. They form a lipid cement between the cells of the superficial layer of the epidermis. Consequently, they reduce skin dryness by maintaining skin hydration. The main fatty acids include omega-3, 6, and 9, which you will find in vegetable oils (soybean, rapeseed, sunflower, evening primrose, borage, etc.) or oilseeds (walnuts, almonds, hazelnuts, chia seeds, etc.).
Other Antioxidants
There are other antioxidant nutrients often included in skin supplements, for example:
- Selenium helps protect cells from oxidative stress. It is found in fish and seafood, among other foods.
- Beta-carotene brightens the complexion, hydrates the skin, and helps renew dermal cells. It is found in carrots, apricots, mangoes, melons, and yellow peaches.
- Polyphenols are found in grapes, dark chocolate, artichokes, and other foods.
