It can be found in: carrots and yellow and green vegetables and fruit. The transformation of provitamin into vitamin occurs in the liver and intestines, vitamin A is absorbed from the digestive tract, and 90% of retinol is stored in the liver.

There are several types of retinoids. You can divide them into:
- retinoic acid – may irritate the skin and cause redness and flaking;
- retinyl-palmitate and retinyl acetate – have a weaker effect compared to retinol. Their action is based on moisturizing and preventing keratosis; they act as antioxidants;
- beta-carotene (provitamin A) – used in cosmetics provides antioxidant properties;

Retinol is also used to treat acne skin. It has an exfoliating and normalizing effect, thanks to which it cleanses skin pores, regulates the amount of secreted sebum and soothes inflammation. During the treatment, the skin’s condition improves – it becomes elastic, smooth and toned. Retinol evens out skin tone brightens discolorations and reduces the visibility of broken blood vessels.
