DESCRIPTION: 4-Butylresorsinol is a powerful and safe whitening and skin-lightening agent. It has been compared with Hydroquinone, kojic acid, arbutin, and including other forbidden toxic ingredients and showed superior efficacy with tyrosinase inhibition
4-Butylresorsinol (4-BR) is a strong tyrosinase and peroxidase inhibitor. 4-BR works very well against hyperpigmentation including more complex pigmentation such as melasma. In more recent studies, 4-BR has proved effective in even rinse off products – 4-Butylresorcinol was added to both liquid and solid soap formulations and showed significant lightening effects after only a few weeks of treatment. 4-BR also has strong efficacy against oxygen-induced DNA damage – working both to promote a brighter and more even skin tone as well as skin ageing.
APPLICATIONS: Can be used in creams, chemical peeling, cleansers, soaps, and skin treatments.
