Is Spray Tanning Safe? What You Need to Know Before Your First Session

Is spray tanning actually safe? We break down what the science says about DHA, FDA guidelines, and how to tan without the risks.

If you’re thinking about getting a spray tan but you’re hesitating because of safety concerns, you’re not alone. “Is spray tanning safe?” is one of the most Googled questions we hear. Here’s the honest answer.

The active ingredient in almost every spray tan solution is DHA (dihydroxyacetone). U.S. FDA regulations have permitted DHA for external use on the skin since the 1970s, and it gives you colour without any UV exposure.

How DHA Works

DHA reacts with the dead skin cells on the very top layer of your skin (the stratum corneum), creating a temporary brown colour that fades as those cells naturally shed. Most of it stays in that outer layer: lab studies suggest less than 1% of DHA applied to the skin reaches the bloodstream. And unlike UV tanning, no radiation is involved.

The FDA’s Stance

The FDA hasn’t approved DHA for all-over spraying in tanning booths specifically, because safety data for that use hasn’t been submitted for review, and DHA isn’t approved for the eyes, lips or other mucous membranes. The FDA advises protecting your eyes and mucous membranes and avoiding breathing in the mist. That’s why at TANNED TO we provide complimentary nose plugs and recommend keeping the mist away from your face.

Compared to the Alternatives

Here’s what we know for certain: UV exposure from the sun and tanning beds is a proven cause of skin cancer and premature aging, and Health Canada puts it plainly: “There is no safe way to tan.” A spray tan gives you the look of a tan with no UV at all. For most people, that trade-off is a no-brainer.
