However, it is not clear whether dihydroxyacetone (DHA)\u2010based 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\u2010induced erythema.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Fifty\u2010one healthy volunteers of skin type III to IV who came to the hospital were recruited in this study. A 308\u2009nm 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 (Group A), irradiation without camouflage (Group B), camouflage without irradiation (Group C), and camouflage plus irradiation (Group D). Refined MED was evaluated via naked eyes (erMED) and digital dermatoscopes (drMED), The erythema index (EI) value of the targeted site was measured by dermatoscopic digital imaging and analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      After the camouflage masking, 43 (84.3%) subjects remained unchanged in erMED, 7 (13.7%) had a MED increase of one grade (+10\u2009mJ\/cm\n                      <jats:sup>2<\/jats:sup>\n                      ), and only one (2.0%) had a MED increase of two grades (+20\u2009mJ\/cm\n                      <jats:sup>2<\/jats:sup>\n                      ).
