Too much sun is no good for us – and neither are tanning beds. So what about sunless tanning?

Sunless tanners seem harmless enough – so are they safe? 

Dermatologist Arthur Perry says, not really. Sunless tanners contain a chemical called DHA. You smear or spray that on and it turns your skin brown – instant tan! But DHA is toxic if you inhale it or if it gets in your mouth or eyes. Holding your breath won’t eliminate the risks. Once you apply the sunless tanner, that DHA chemical combines with the amino acids in the skin, increasing free-radicals by 180% - not good. Dr. Perry also says DHA is mutagenic, which means it damages DNA and kills healthy cells.
