What are antioxidants?
We have heard of them an infinite number of times, always in a positive light and as elements that are quite beneficial for the body, but what are antioxidants, really? What is their purpose?
What are antioxidants?
Antioxidants are a group of molecules that are able to slow down or prevent cell oxidation. This group of vitamins, minerals and other phytochemical substances serve as a barrier against free radicals, molecules that harm cells and cause premature ageing of the skin, as well as different ailments and illnesses.
How do antioxidants benefit the dermis?
- They stimulate the production of collagen, a protein which is essential for maintaining the skin’s firmness and elasticity. The dermis is made up mostly of collagen, a substance created by the body on a regular basis but whose production significantly decreases with age. This decline begins around 25 years of age and intensifies starting at 40 years of age. We must therefore look for alternatives that can help us with collagen production.
- They prevent certain skin problems, such as acne. Vitamin A is responsible for preventing acne. It is a powerful antioxidant that aids in reducing the production of sebum, which in excess leads to the appearance of acne.
- They reduce the appearance of skin blemishes. Specifically, vitamin C reduces skin pigmentation and breaks down melanin, thus proving highly effective against skin blemishes while also preventing damage caused by the sun’s rays. Vitamin C also boosts collagen synthesis which helps to keep the skin firm and elastic.
Where are they found?
In general, foods of plant origin are a source of antioxidants, but they are not the only one. Many foods contain these substances.
- Vitamins are powerful and effective natural antioxidants. Spinach, carrots, egg yolk and bananas are rich in vitamin A, while green peppers, kiwi, oranges and blueberries have high vitamin C content. Another antioxidant that is essential to your diet is vitamin E: it is highly useful in fighting skin ageing and in improving the appearance of scars thanks to its regenerative properties. Include wheat germ, hazelnuts, broccoli and pistachios in your diet to boost vitamin E intake.
- Some minerals have properties that are highly beneficial for the skin. Zinc, present in wheat germ, wheat bran and sunflower seeds, helps to regulate the activity of the sebaceous gland, thus making this mineral very useful in the prevention of acne; it also strengthens hair follicles and the scalp, thus reducing hair loss. Selenium favours the repair of damaged tissue and helps to keep skin smooth. It is found in foods such as the Brazil nut, almonds and mushrooms. Another great ally to the skin is copper, a mineral that helps to reduce expression lines and minimise skin blemishes; also, thanks to its antimicrobial properties it greatly contributes to the processes of scarring. Beets, sesame seeds and oats have high copper content.
- Topical use. In addition to the vitamins and minerals mentioned here, there are specific products which, when applied topically, have huge benefits for the skin; some of these products are our proteoglycan ampoules. Formulated with a high dose of pure vitamin C, these ampoules act on young skin by helping to prevent premature ageing, and on mature skin by fighting wrinkles, sagging skin and other signs of ageing.
The most complete and effective way to maintain the skin’s smoothness, glow and elasticity is by combining healthy nutritional habits, which include antioxidant-rich foods, and reinforcing them with specific dermo-cosmetic products that also contain them.
