Kojic acid dipalmitate powder is an improved kojic acid derivative that overcomes the kojic acid's instability of light, heat and metal ions while maintaining the inhibition of tyrosinase activity of kojic acid and the blocking of melanin formation in the skin The effect, and this inhibition is more intense than kojic acid, making it a new generation of highly effective whitening active agent. As a fat-soluble whitening active agent, kojic dipalmitate powder can be more effectively absorbed by the skin and at the same time brings good moisturization to the skin in addition to being easier to formulate.
