A garment for treating skin of a wearer with an active ingredient, comprising:(a) a knitted garment material selected from the group consisting of one of nylon and polyester adapted to be worn tightly against the skin and having a multiplicity of durable chemical binding sites;(b) a binding agent molecule selected from one of the polyimines which are the durable binding sites, each binding agent molecule having at least one semi-durable chemical binding site which can be broken by at least one of the skin conditions of skin pH, skin moisture and skin heat; and(c) an active ingredient selected from one of theophylline and silantriol being bound to each semi-durable chemical binding site so that the active ingredient remains chemically bound to the garment when the garment is not worn and so that the active ingredient is released to the skin when the garment is being worn, and the semi-durable binding sites on the agent molecule are exposed to at least one of skin pH, skin moisture and skin heat serving to break the chemical bonds between the active ingredient and the binding agent molecules.
