  • COMPOSITION FOR SKIN WHITENING COMPRISING BETA-MANGOSTIN AS EFFECTIVE INGREDIENT
    Publication number: 20180256486
    Abstract: A skin whitening composition includes ?-mangostin or a cosmetically acceptable salt thereof as an effective ingredient. ?-Mangostin represented by Chemical Formula 1 suppresses the expression of tyrosinase and TRP-1 (tyrosinase-related protein-1) and induces autophagy of a melasosome. As such, it was confirmed that the ?-mangostin not only suppresses melanin production but also exhibits the effect of removing previously formed melanin. Accordingly, the ?-mangostin can be advantageously used as a functional material for skin whitening and skin lightening.
