4-Butylresorcinol is a derivative of resorcinol that can inhibit both tyrosinase and tyrosinase - related protein - 1 (TRP - 1). It can be used to reduce skin irritation and is also known to suppress melanin production. Its ability to lighten skin pigmentation was first reported in 1995. Many subsequent studies have verified its effectiveness and safety in treating melasma when used in a 0.1% cream. However, there are few clinical studies on the 0.3% cream.
