Sunless tans are a popular and safe way to “tan.”  According to the American Academy of Dermatology the best sunless tanning products contain an ingredient called DHA, this ingredient causes the dead skin cells to turn brown.  Those dead skin cells shed constantly so the color will fade over five to seven days.  DHA is not absorbed into the body and has no known toxicity.  DHA is cleared and regulated by the FDA and is a better alternative to the sun damage cause by repeated and excessive sun exposure.
