Airbrush spray tanning is safe during pregnancy as long as the salon gives eye, ear, nose and mouth protection to wear during the application process, according to BabyMed.com. Obstetricians recommend waiting until after the first trimester to use any artificial tanning products.
Self tanners contain dihydroxyacetone (DHA), an ingredient that temporarily stains the skin. BabyMed.com states that DHA has been used in cosmetics for years without problem, and there is no evidence that it absorbs into the bloodstream, although doctors prefer to err on the side of caution. Due to changing hormones during pregnancy, spray tanners may cause skin irritation, and because some women become extremely sensitive to smells, these products may be too overbearing.
