But the ability to sniff out faux sun worshippers will now be blunted--literally. Two brands have found a way to combat the awful odor that arises when the active ingredient in self-tanners--dihydroxyacetone (DHA)--reacts with skin. St. Tropez is using Aromaguard, a technology said to reduce the scent of DHA by 70 percent, and Hawaiian Tropic's new products contain "odor synthesis technology," which also cuts down on DHA's smell. Now if only someone could invent a cure for orange palms.
