Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 10 / 624,227, filed Jul. 22, 2003, which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]The present invention contains a unique combination of active ingredients for topical application. Together, these compounds seem to potentiate their effects and work in a synergistic matter. In addition, the composition of the present invention is prepared in a topical delivery system that enhances skin penetration. The composition is particularly useful for treating hyperpigmentation disorders such as melasma, postinflamatory hyperpigmen-tation, irregular pigmentation secondary to photodamage, lentigenes (age-spots) and others. The composition is nonirritating to the skin and also provides improved facial skin feel benefits. The unique blend is also useful for conditioning, desquamating, and cleansing the skin.

AI Technical Summary

Benefits of technology

"The patent text describes the use of a combination of vismia and phytic acid for skin lightening and the prevention and treatment of melasma, freckles, and age spots. The combination of these ingredients works by protecting the skin from oxidative stress and reducing the production of free radicals. The use of other known skin lighteners, such as arbutin and kojic acid, provides additional benefits. The patent also describes the need for a non-hydroquinone lightening agent that is safe, effective, and has minimal side effects."

Problems solved by technology

Vismia, phytic acid, arbutin and kojic acid provide suitable substitutes for hydroquinone, which has been utilized in the last decade as a skin lightening agent, but has been reported to create adverse effects in many who use it.

It has been explained earlier that oxidative stress damages cellular elements, which can be repaired with most known antioxidants, such as Vitamin C. Unfortunately, to combat all sources of oxidative stress, it is necessary to use a large number of different antioxidants.
