Problems solved by technology

The skin can become hyperpigmented when too much melanin concentrates at one area or portion of the skin due to the retention time of the melanosomes in the basal layer.
However, such treatment is costly and carries the risks normally associated with anest

Abstract

The present invention relates to compositions useful in treating hyperpigmentation and the various signs of dermatological aging in human skin. The present invention also relates to cosmetic compositions and methods of using such compositions that improve the aesthetic appearance of skin. Further, the present invention relates to methods of applying the compositions to the skin to effect treatment and to improve the aesthetic appearance of skin, particularly, by providing anti-aging benefits to the skin. These and other objects of the present invention are achieved by a method and composition that comprises (a) a de-pigmenting agent or anti-aging agent in an amount effective to prevent, treat and/or ameliorate pigmentation or the various signs of aging at an area of skin to which it is applied, and (b) a cosmetically or pharmaceutically acceptable vehicle. Suitable de-pigmenting agents include 3,3'-thiodipropionic acid, thiazolidine-2-carboxylic acid, Kaempferol-7-glucoside, perilla oil, and clofibrate and clofibrate analogs and/or derivatives, as well as those set forth below. Suitable anti-aging agents include 3,3'-thiodipropionic acid and/or its derivatives.

Description

[0001] This is a continuation-in-part application that claims priority to, and the benefit of, co-pending U.S. Ser. No. 09 / 741,383, filed Dec. 20, 2000, currently allowed and incorporated herein by reference.[0002] 1. Field of the Invention[0003] The present invention relates to compositions useful in treating hyperpigmentation and the various signs of dermatological aging in human skin. The present invention also relates to cosmetic compositions and methods of using such compositions that improve the aesthetic appearance of skin. Further, the present invention relates to methods of applying the compositions to the skin to effect treatment and to improve the aesthetic appearance of skin, particularly, by providing anti-aging benefits to the skin.[0004] 2. Description of the Prior Art[0005] Human skin color is determined primarily by the content of the pigment melanin in the basal epidermis layer. Melanin is synthesized by the process of melanogenesis within melanocytes (pigment-prod...
