Use in Topical Products Show Promise for Skin “Brightening” Effect*

KYOWA GSSG Improved SKin Whitening

Researchers found that skin treated with the 2% KYOWA oxidized glutathione location had significant whitening over the placebo group,” said Ryusuke Nakagiri, Senior Director of Strategic Science at Kyowa Hakko USA.

A recent study of healthy adult women showed topical application of oxidized glutathione may regulate melanin production, resulting in “brightening” or “whitening” of the skin, as shown in the study, published October 17th of this year in Clinical, Cosmetic and Investigational Dermatology.

Thirty healthy women, age 30 to 50, applied a lotion containing Kyowa’s Oxidized Glutathione (GSSG) to one side of their face for 10 weeks. A placebo was applied to the other side. Researchers found that skin treated with the 2% oxidized glutathione location had significant whitening over the placebo group, said Ryusuke Nakagiri, Senior Director of Strategic Science at Kyowa Hakko USA.

Kyowa’s Oxidized Glutathione is aqueous stable, and does not break down in light and heat. GSSG is designed for use in personal care products, and is currently available in European and South American markets. It is backed by Kyowa Quality™, a standard that helps ensure the highest purity and quality of the company’s long line of ingredients and products.

Numerous other studies already have shown the power of glutathione. The number of free radicals attacking the body’s cells increase as people age. Antioxidants, such as glutathione, attack and destroy free radicals, helping to cleanse the body.
