Dihydroxyacetone (DHA) is a popular ingredient in sunless tanner and lotions. We sought to measure the absorption spectrum of hu- man skin after application of DHA. A male in his 30's applied DHA to one underarm once daily for seven days. Re ectance spectropho- tometry was performed on the treated and untreated side. The area treated with DHA revealed increased absorption in the 400-700 nm range. Compared to normal skin, the absorption spectrum of human skin after application of DHA is altered from 400-700 nm. Care should be taking with using lasers in these wavelengths on skin treated with DHA. J Drugs Dermatol. 2016;15(11):1459-1460..
二羟基丙酮（DHA）是一种常用于免晒美黑产品和乳液中的成分。我们试图测量涂抹DHA后人皮肤的吸收光谱。一名30多岁的男性连续七天每天在一侧腋下涂抹一次DHA。对涂抹和未涂抹DHA的部位进行反射分光光度法检测。涂抹DHA的部位在400 - 700纳米范围内吸收增加。与正常皮肤相比，涂抹DHA后人皮肤在400 - 700纳米的吸收光谱发生了改变。在涂抹DHA的皮肤上使用这些波长的激光时应格外小心。《药物皮肤病学杂志》。2016年；15(11):1459 - 1460。
