The main active ingredient of CIMEL peeling is retinol. Retinol, without damaging the skin, normalizes the processes of keratinization, restores the extracellular structures of the dermis and produces a pronounced whitening effect. Histological studies have shown that the stimulating effect of retinol and its derivatives on the cellular structures of the skin persists for 4 months after the last application of retinoids. As the peeling active ingredient is retinol, but not retinoic acid, it is preferable to use the product by patients with sensitive skin. It should also be noted that peeling contains kojic acid, which helps to whiten the skin.
