Abstract: PURPOSE:To obtain an external agent having excellent melanin-suppressing effect (skin-beautifying effect) and high safety, by compounding castanospermine as an active compound. CONSTITUTION:The objective external agent having remarkable skin-beautifying effect and high safety can be produced by adding preferably >=0.01wt%, especially 1-20wt% castanospermine of formula as an active component to various external agents such as ointment, gel, pack, cream, foundation, sebaceous gland activation cosmetic, etc. The melanin-suppressing and skin-beautifying effects of the above active component are absolutely different from those of conventional skin-beautifying agent and are supposed to be based on the conversion of the sugar chain of tyrosinase to suppress the development of tyrosinase activity. The above external agent may be compounded with other drug-active components such as anti-inflammatory analgesic agent, etc., in addition to the above active component. Especially, the effect can be promoted by the addition of a substance capable of improving the increasing tendency of melanin in epidermis by delaying the keratinization of cuticle.
