MELANOGENESIS REGULATOR

摘要

It is intended to provide compositions such as a melanogenesis regulator having a function of effectively controlling skin pigmentation or skin pigment loss, a skin color controller and an external skin agent having a function of regulating melanogenesis and controlling the skin color. A melanogenesis regulator containing a melanogenesis inhibitor and a melanogenesis promoter and a skin color controller can achieve the above object. Also, compositions such as a melanogenesis regulatory composition containing a melanogenesis inhibitor and a melanogenesis promoter can be provided and these compositions may be in the form of external skin agents such as an external skin agent for controlling the skin color. By blending a melanogenesis inhibitor and a melanogenesis promoter at an appropriate ratio, a desired amount of melanin can be obtained so that the skin color can be controlled to, for example, a color desired by a user.
