Peels are procedures that cause a desquamation of the skin in order to renew it. The peels are performed with the aid of a device (diamond peeling) that provides the removal of the stratum corneum, which is the layer of dead cells in the skin. Then follows the application of a retinoic acid (a substance that is quickly absorbed by the skin, which will provide skin renewal) peel. Two days after the peel, the skin will lightly flake. It is very important to avoid sun exposure in this period.
