Vitamin A is a popular ingredient in fighting acne, reducing wrinkles, stimulating collagen and stimulating cell turnover. Vitamin A exists in different forms. On the one hand there is tretinoin, the most effective form of vitamin A, which is only available on prescription . On the other hand, there is Retinol, a less effective form of vitamin A, developed by cosmetic companies as an anti-aging ingredient. Retinol has positive effects on the skin and can be used in your 30's to reduce signs of aging. Just note that there are some drawbacks that you should definitely take into account:
- It's an unstable ingredient that oxidizes quickly. Look for products with a light and airless packaging.
- Retinol products containing 0.3 % or a lower concentration are not effective.
- Retinol may have an irritating effect on your skin.
- Do not use vitamin A derivatives when you are pregnant or want to become pregnant.
- Use it as a cure , not permanently!
- Complete a cure during winter. Vitamin A derivatives make your skin more sensitive to the sun and should therefore not be applied during the summer.
