Is Spray Tanning Safe?

The FDA’s concern is with spray booths more than lotions. It says dihydroxyacetone, or DHA, a color additive that darkens the skin by reacting with amino acids in its surface, is approved only for external application, which does not include the lips or any body surface covered by mucous membrane, and is not permitted for use in the area of the eye. It says the use of DHA as an all-over spray in tanning booths has not been approved, since safety data to support that use have not been submitted.

In a spray booth, the FDA says it may be difficult to avoid exposure of the eyes, lips or mucous membranes, or even internal exposure, and it advises asking whether a facility protects you around the eyes, on the lips and mucous membranes, and from inhaling or ingesting the product. It says creams and lotions sold in stores are used the way DHA is approved, and that consumers can easily avoid inhaling them or applying them near the eyes. The FDA has received reports of rashes and, primarily with spray tanning booths, coughing, dizziness and fainting, though it says it is uncertain what, if any, ingredient caused them.

A sunless tan is not sunscreen. The FDA says only sunless tanners that contain sunscreen ingredients and carry an SPF number may provide protection, and that tanning products without sunscreen must carry a warning that they do not protect against sunburn and that repeated exposure of unprotected skin while tanning may increase the risk of skin aging, skin cancer and other harmful effects. It also notes that ingredient labeling rules do not apply to products used only by professionals, such as those in spray tanning booths.
