Abstract: 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.
