Clinical studies of retinol demonstrate that it has anti-oxidant properties and cell-communicating benefits that provide anti-aging benefits including brighter skin, improved firmness and fewer wrinkles. Retinol is vitamin A and it is converted into retinoic acid after being absorbed into skin activating skin cells to function like younger skin cells. New advances in the stability of using pure retinol in skin care products have delivered more functionality in creating healthier skin cells and providing increased collagen synthesis, improvements in cellular turnover and a stronger skin structure. Forms of retinol in skin care include retinol, retintyl palmitate, tetrinoin and tazarotene.
