Middle is carried

The depth of exposure to any peeling, including chemical, is different. The impact is divided into a surface procedure, middle peeling and deep. The surface procedure exfoliates only the horn cells of the upper layer of the skin — epidermis. For this, there are enough fruit acids in the desired concentration. Middle is carried out with damage, and then exfoliating the cells of the median layers, deep — all layers of the epidermis.
