The term "peel", literally means to strip off or come off in sheets or scales. In dermo-cosmetics, peels are used to cause an accelerated skin cell turnover for different purposes: cleansing, nourishing, moisturizing, astringency, reducing ageing effects, anti-seborrheic action, depigmenting, etc.

Nowadays, chemical peels are regarded as a better and less invasive treatment option which helps keep a healthy, beautiful skin, and can also contribute to inhibit signs of ageing. Their use is not limited to single treatments, since they are often used as complements or basic steps in other dermo-cosmetic procedures, such as microdermabrasion, mesotherapy, skin fillers. etc.

According to the depth of action of the substance in use, the peel can be: - Superficial: causes the destruction of the stratum corneum and partial destruction of the epidermis. - Medium depth: causes total epidermal destruction and total or partial destruction of the papillary dermis. - Deep: induces the total destruction of the epidermis and the dermis reaching the mid reticular dermis.
