Abstract
A process for obtaining an active principle with firming effect for the skin, obtained from wheat protein, provided to counter the aging of the skin includes in succession the following steps: a) crushing grains of fresh wheat so as to obtain flour; b) dissolving this fresh wheat flour in water; c) hydrolyzing this solution in the presence of proteases; d) effecting a gross separation of the soluble and insoluble phases, e) concentrating the active fraction; and f) sterile filtering to retain the microorganisms, yeast and molds as well as the total mesophilic flora.

A process for firming the skin to counter the effects of aging, comprising applying to the skin of a person in need of the same a cosmetologically effective amount of a composition obtained from wheat proteins by crushing grains of fresh wheat so as to obtain a flour, dissolving this flour in water, hydrolyzing the solution thus obtained in the presence of proteases, separating the soluble and insoluble phases in the hydrolyzed material, and concentrating the soluble phase thereby to concentrate the active principle thus obtained, the molar mass of the different molecular species present having a principal peak at about 15,000 Daltons.
