METHOD FOR PROCESSING 4-SUBSTITUTED BENZOIC ACID DERIVATIVES HAVING 3, 4-METHYLENE- OR 3,4-ETHYLENEDIOXYBENZENE MOIETY AND THE USE OF THE SAME FOR ANTIAGING COSMETICS

-

Page/Page column 15; 16, (2008/06/13)

The present invention relates to a method for preparing 4-substituted benzoic acid derivatives having a 3, 4-methylenedioxybenzene or 3, 4-ethylenedioxybenzene backbone, and the use of the derivatives for antiaging cosmetics. More particularly, the invention relates to a method for preparing 4-substituted benzoic acid derivatives, which have a 3, 4-methylenedioxybenzene or 3, 4-ethylenedioxybenzene backbone and show the effect of stimulating the production of collagen, elastin, fibrillin and glycosaminoglycan, which are the main constituents of the skin's dermis, and to the use of the derivatives for antiaging cosmetics, which have the effect of reducing skin wrinkles.
