Panax ginseng is known for various pharmacological activities mainly due to saponins. Since minor saponins, generated by the decomposition of major saponins, generally exert higher activities than major saponins, the fermentation may increase the minor saponin contents in ginseng products. In this study, we tested fermented ginseng extract whether or not provide a safe cosmetic ingredient for whitening purpose. In this regard, fermented Ginseng extract was prepared and evaluated the inhibitory activity toward tyrosinase and the melanin synthesis suppression. The safety was tested via cell viability and toxicity test. The skin lightening effect was also evaluated by clinical study. The fermented Ginseng extract exerted higher activities in tyrosine inhibition and in suppressing melanin synthesis compared to Kojic acid and arbutin. In the clinical test, skin lightening effecte of the sample was clearly higher than vehicle or Vitamin C. We thus concluded that the fermented Ginseng extract may provide a safe cosmetic ingredient for skin lightening purpose.
