STRENGTH OF SKIN PEELS. Superficial peels are the mildest type of chemical peel and can be used on all skin types. These mild peels remove only a small part of the epidermis or outer layer of skin and are most often used to improve the appearance of fine lines, mild scarring and minimal hyperpigmentation.kin Tightening. After the acid is neutralized, skin will feel dry & tight for the first day or two. If a light strength peel was used, skin may become wrinkled & flakey.
