The retinoic acid is considered a superficial peel because it can reach the stratum corneum, granulosum, stratum basal cell layer, until the dermo ephidermal junction.

It was concluded that use of retinoids for the treatment of skin is known since the 1970's and Unilever industry has the largest number of deposits.
