Abstract

Abstract A topical composition adapted upon application to the skin to minimize the objectional appearance of surface irregularities, blemishes and discolorations by causing a superficial slough of the damaged portions of the epidermis and a beneficial stimulation of the connective tissue cells of the dermis. The active ingredients of my composition are those furnished by source materials capable of providing active forms of salicylate, resorcinol, phenol and zinc compounds, or are the compounds per se. Additional my composition may contain relatively nonessential ingredients such as substantially anhydrous, nonreactive emollients, demulcents, anesthetics and antiseptics, as for instance glycerin, camphor and lanolin. Instead of using phenol, itself, in my composition it is preferable to use an inactive or inhibited form of phenol, such as an ammonium or alkali metal phenate, or phenolate, capable of being rendered active by exposure to the moisture and carbon dioxide of the atmosphere, which together form carbonic acid (H2CO3).
