Abstract:
PURPOSE: A flexibility improvement degree evaluation method of cosmetic products and skin is provided to evaluate skin flexibility based on an average displacement value of the skin, thereby quantitatively evaluating a flexibility improvement degree. CONSTITUTION: A skin flexibility evaluation method utilizes a stretching degree of skin when pressure is applied on the skin. An evaluation method utilizes a cutometer which measures a restored degree of the skin when the pressure is removed. The flexibility estimation method evaluates a corneous layer of the skin. A cosmetic material is sprayed on the skin. The pressure is applied after 0.1 to 6 hours of spraying the cosmetic material on the skin.
