Retinols are non-irritant derivatives of the retinoid or vitamin A family. Creams containing 0.30% retinol, is a concentration that is generally suitable for dry and sensitive skin exposed to the elements, oily or with acne, respectively.
Retinol works by intensifying cell division and enzyme activity, which deeply regenerates the skin. The epidermis and dermis become thicker and the skin becomes more elastic. There is an increase in collagen production and stimulation of hyaluronic acid, which keeps the skin well hydrated. Wrinkles and fine lines are reduced, the skin regains a firmer, soft and refined texture, for a radiant complexion.
