A composition, a method, and a kit are provided for chemical skin peeling, based on nano-structured thixotropic inorganic gels, which have a higher potency and are less irritant of the conventional peeling formulations. The gels of the invention can easily be applied on the skin, where they form a stable, uniform layer, that doesn't strain. The kit comprises by a defatting gel, different types of peeling gels and a neutralizing gel. The defatting gel is characterized by a markedly enhanced defatting capacity in comparison to the conventional products, because the sebum solubilized by the solvent is strongly adsorbed on the huge surface of the nano-structured material of the gel. The peeling gels are based on conventional peeling compounds, such as glycolic acid, trichloroacetic acid, pyruvic acid, salicylic acid, Jessner solution, but the presence of nano-structured material strongly increases the peeling effect, allowing the use of lower concentrations of peeling compound, with only minimal skin irritation for the user. The neutralizing gel is characterized by a color change that allows the operator to verify in real time the neutralization of the peeling agent on the treated skin surface. All the gels of the invention can be easily removed from the skin after the treatment. The thixotropic gels of the invention can be used in chemical skin peeling for the treatment of various cosmetic conditions and dermatological disorders, including dry skin, acne, dandruff, keratoses, age spots, wrinkles and disturbed keratinization.
