摘要：
Skin can be lightened by application of a composition containing a skin lightening amount of niacin and a physiologically acceptable carrier. Such a composition contains from 0.2% to about 10% by weight of niacin and optionally also a compound which absorbs ultra-violet light in the range 290-360 nm to counteract the tanning and burning effect of sunlight.
