Mechanism of Action

Hyperpigmentation is a common condition that affects the skin. It is caused by the buildup of melanin in particular areas or patches of the skin, which causes those areas to look darker than the surrounding area of skin. It can occur because of aging or disorders like melasma. Enzyme tyrosinase is the most important regulator of melanin synthesis.

4-n-Butylresorcinol inhibits directly the activities of tyrosinase and tyrosinase-related protein-1 (TRP-1), which are enzymes necessary for the production of melanin pigment and thus inhibits melanin production.


  • It is frequently found in cosmetics used for hyperpigmentation, where it serves the purpose of a depigmenting agent.
  • In addition to this, it is an extremely efficient skin-whitening agent that can help reduce the appearance of age spots.


Q. Is 4-butylresorcinol safe?

It is found that in addition to being  highly effective as a depigmenting agent, it is very well tolerated with extremely rare cases of skin sensitivity. Further, it can also be used during pregnancy.
