Facial peel treatment reduces the appearance of spots, freckles, scars or some irregularities of the facial skin, improving the appearance of fine lines and wrinkles, and increasing skin smoothness and compaction. The result leads to a smoother and brighter looking aspect. Facial peels are intended to renew the more superficial layers of the skin in order to correct imperfections. The treatment involves applying a substance to the skin surface, which stimulates the renewal of skin layers. These can be classified in three groups: superficial, medium and deep.
