4. Mechanism of Action

• Kojic dipalmitate inhibits tyrosinase activity by binding to copper ions, preventing copper ions from activating tyrosinase. This blocks or delays melanin formation, inhibits the production of melanin-induced dark spots and freckles, promotes skin metabolism, and rapidly eliminates existing melanin pigments.
