Resveratrol is a known potent antioxidant found in red grapes and associated with various health benefits. 60 0 Skin pigmentation involves many genes at various steps. A gene expression test (RT-PCR) has been performed and showed that REGU®-FADE (0.002%) is very effective in attenuating the melanin production cascade at multiple points. 100% 80 20 Lighter skin Skin brightening is one of the fastest growing segments in the cosmetic industry. In Asia skin brighteners are widely used to make skin fairer. In Western countries consumers want to diminish age spots, reduce excessive pigmentation and achieve an even skin tone. As a consequence, these markets are looking for increasingly efficient, fast-acting skin brighteners. At the same time, these actives must be absolutely safe for cosmetic use.
