Abstract
A whitening embellisher includes, as an active ingredient, teprenone (chemical name: geranylgeranylacetone). A whitening and beautifying composition includes teprenone and one or more substances selected from kojic acid, L-ascorbic acid and the like. The whitening embellisher, and whitening and beautifying composition prevent the skin from pigmenting and darkening due to sunburn and/or aging, and quicken fading, and hence make spots and freckles inconspicuous when the preparations are used for external application as a cream or milky lotion.
