PURPOSE: To provide a cosmetic obtained by compounding L-ascorbic acid-2- sulfate or its salt with vitamin E, and having improved transcutaneous permeability, synergistically increased beautifying effect, and improved effect to prevent the aging, without lowering the stability of the former component.
CONSTITUTION: A cosmetic having remarkably improved beautifying and aging- preventive effect can be produced by compounding L-ascorbic acid-2-sulfate or its salt (e.g. salt of Na, K, Mg, Ca, etc.) and a vitamin E compound (e.g. α-, β-, γ-tocopherol, tocopherol acetate, etc.). The use of 10wt% L-ascorbic acid-2- sulfate and 2wt% vitamin E is sufficient to attain the above effects. The combined use of the above components enables the increase in the transcutaneous permeability and the remarkable improvement in the spots and freckles without lowering the stability of L-ascorbic acid-2-sulfate. The content of soluble collagen in the living tissue can be increased to prevent the aging of the body.
