It is intended to provide substances which are efficacious in whitening the sunburned skin after UV-irradiation and preventing, relieving and treating pigmentation in the skin such as spots caused by sunburn or the like, freckles and liver spots, and compositions containing the same. The above object is achieved by using melanogenesis inhibitors and whitening agents comprising ergosterol derivatives; melanogenesis inhibitors and whitening agents containing the above ergosterol derivatives; melanogenesis inhibitory compositions and whitening compositions containing the above ergosterol derivatives; cosmetics, drugs, external skin preparations, melanogenesis inhibitory foods and whitening foods containing the above ergosterol derivatives; and the above-described compositions, cosmetics, drugs, external skin preparations, melanogenesis inhibitory foods and whitening foods containing the above ergosterol derivatives together with whitening component(s) other than the ergosterol derivatives. Thus, novel melanogenesis inhibitors and whitening agents as well as compositions having a melanogenesis inhibitory effect and a whitening effect such as cosmetics, drugs, external skin preparations and foods can be obtained. |
