Abstract
Chloasma (melasma), an acquired hypermelanosis, is often recalcitrant to various treatments and an amenable, as well as safe, pigment-reducing modality is needed. We investigated that the reducing effect of proanthocyanidin, a powerful antioxidant, on chloasma in a one-year open design study. Proanthocyanidin-rich grape seed extract (GSE) was orally administered to 12 Japanese woman candidates with chloasma for 6 months between August 2001 and January 2002 and to 11 of these 12 for 5 months between March and July 2002. Clinical observation, L* value (lightening) and melanin index, and size (length and width) measurements of chloasma were performed throughout the study period. The first 6 months of GSE intake improved or slightly improved chloasma in 10 of the 12 women (83%, p
