The scare of skin cancer being caused by UV rays has made people turn to sunless tanning or a spray tan. The best sunless tanning sprays contain DHA (dihydroxyacetone) as the active ingredient. DHA is a chemical that mixes with dead skin cells to produce the appearance of a tan.
The only draw back to this type of tanning is that it lasts only 7 – 10 days due to the shedding of dead skin cells. DHA has no known side effects for external application as long as the eyes, lips and mucous membranes are protected. Those who get this sunless tan must keep in mind that it is not a real tan so they can still burn from UV ray exposure.
