Kojic acid is a specialized inhibitor for melanin. It prevents tyrosinase activity through synthesizing with copper ions in cells after entering skin cells. Kojic acid and its derivatives provide enhanced inhibitory effects on tyrosinase compared to conventional skin whitening agents. It is commonly utilized as a high-performance whitening or depigmenting agent at a 1% concentration.
