    Kojic acid dipalmitate

    Kojic acid dipalmitate is an improved kojic acid derivative, which overcomes the instability of kojic acid to light, heat and metal ions, and maintains the tyrosinase inhibitory activity of kojic acid and blocks the formation of skin melanin. And this inhibition is stronger than kojic acid, making it a new generation of high-efficiency whitening actives. As a fat-soluble whitening active agent, kojic acid dipalmitate, in addition to being easier to formulate, can be absorbed by the skin more effectively, and at the same time, it can bring good moisturizing effect to the skin.
