Product Description

Product Description

Kojic Acid Powder

Kojic acid is a specialized inhibitor specifically targetting melanin synthesis. Upon penetrating the outer layers of the skin, it effectively prevents tyrosinase activity by binding with copper ions within cells. Research indicates that Kojic acid and its derivatives exhibit a significantly higher inhibitory effect on tyrosinase activity compared to alternative skin whitening agents. It is most commonly formulated as a skin-brightening or depigmenting agent at a standard concentration of 1%.
