Hyperpigmentation is believed to be related to the enzyme tyrosinase which produces melanin. Among several chemicals known to inhibit tyrosinase production, such as hydroquinone, arbutin, and kojic acid, 4-butylresorcinol has been found to be the most powerful inhibitor by a wide margin.

Mechanism of Action:

In the three processes of melanin source synthesis, 4-butylresorcinol not only had an important inhibitory effect on tyrosinase activity, but also had a synergistic effect on the whitening activity.

●Before melanin synthesis, it interferes with tyrosinase synthesis and glycosylation, preventing the enzyme from being absorbed by melanosomes;

●During melanin synthesis, inhibitory enzyme activity acts as a competitive inhibitor of tyrosinase and TRP1 enzymes, reducing the formation of byproducts that promote melanin primordial formation;

●After melanin synthesis enhances tyrosinase degradation, inhibits melanosome transfer to keratinocytes, and has photostripping effect due to fatty acid action.  This function is enhanced by the presence of fatty acids and modulates tyrosinase degradation.
