Abstract
A sunless tanning formulation is provided to impart a cosmetic coloring effect to skin. The formulation is particularly useful to camouflage the effects of vitiligo. The formulation has both makeup coloring components for instant coloring effect, and dihydroxyacetone for a lasting coloring effect. The formulation is a water-in-oil emulsion with water being the inner phase and oil being the outer phase. A method of camouflaging depigmented splotches resulting from vitiligo using dihydroxyacetone is also provided.
