Q&A: Is It Safe to Spray Tan While Pregnant?

Spray tanners or sunless tanners contain dihydroxyacetone, or DHA, which may be absorbed into your bloodstream either through your skin or by inhaling the spray. The effects of DHA on the pregnancy are simply not known — but it hasn’t been proven to be safe in pregnancy. My general advice is to avoid it until it has been proven to cause no harm.
