Durability of the sun protection factor provided by dihydroxyacetone
Photodermatology, Photoimmunology & Photomedicine, 2004Background/Purpose: The sunless tanning agent dihydroxyacetone (DHA) is known to protect against longwave ultraviolet radiation (UVA) and visible light. Recently, our laboratory has shown that DHA in addition offers a modest sun protection factor (SPF) in humans. We conducted this study in order to investigate the durability of the SPF provided by DHA.
