Effect of a Dihydroxyacetone-Based Camouflage Agent on Ultraviolet-Induced Erythema.

ABSTRACT:

Background

Vitiligo is an acquired, idiopathic skin disease of dyspigmentation, affecting approximately 0.5%-2% of the global population. However, it is not clear whether dihydroxyacetone (DHA)-based camouflage could affect the effectiveness of ultraviolet (UV) therapy. Therefore, we aimed to investigate the effect of a camouflage agent containing 3.6% DHA on UV-induced erythema.

Methods

Fifty-one healthy volunteers of skin type III to IV who came to the hospital were recruited in this study. A 308 nm excimer UV lamp was used to perform the minimum erythema dose (MED) test on the lower back and a camouflage agent containing 3.6% DHA was applied. Four groups were tested on the same individuals (subjects served as their own controls), including no camouflage nor irradiation (G
