Melanin is known not only for its role in pigmentation but also for its impressive antioxidant properties. The initial steps of melanin formation involve oxidation processes. The primary mechanisms for reducing freckles include antioxidant effects and competitive inhibition, both of which are present in DropBright®4BR. Throughout all three stages of melanin synthesis, DropBright®4BR demonstrates a significant inhibitory effect on tyrosinase activity and enhances whitening effects through its synergistic action. Consequently, DropBright®4BR is recognized as a highly effective skin whitening agent.

DropBrigt®4BR (4-butylresorcinol) has a potent inhibitory effect on tyrosinase activity. On the one hand, it can bind to the double copper ion of tyrosinase, the active site of tyrosinase, which competitively inhibits tyrosinase.
- Before melanin synthesis, it inhibits tyrosinase synthesis and glycosylation, preventing the enzyme from being absorbed into melanosomes.
- Inhibition of enzyme activity that acts as a competitive inhibitor of tyrosinase and TRP1 enzymes during melanin synthesis reduces the production of melanin-specific byproducts.
- After melanin synthesis, tyrosinase increases the breakdown of melanocytes, inhibiting keratinocyte migration and acting as a fatty acid photo-removal agent. This function is enhanced by the presence of fatty acids, which regulate tyrosinase breakdown.
