Can spray tans cause cancer? The science (and how Tanzola keeps you safe)

If you love a glow but hate sun damage, you’ve probably wondered: Are spray tans actually safe? Short answer: when used on skin as directed, sunless tanning with DHA is widely considered a safe alternative to UV tanning — and far safer than sunbaking or solariums. The main caution is avoiding inhalation or ingestion during a spray session. Here’s the full picture, minus the scare tactics.

First, how do spray tans work?

Most self-tanners and professional spray tans use dihydroxyacetone (DHA), a sugar that reacts with amino acids in the outermost layer of your skin to create that temporary bronze. It doesn’t interact with deeper, living skin cells and fades as you naturally exfoliate. Cleveland Clinic+1

What does the evidence say about cancer risk?

• Topical DHA (lotions/foams/mousses) used on intact skin is considered safe as a cosmetic colour additive; major cancer organisations position sunless tanning as a safer choice than UV tanning. There’s no clinical evidence linking topical DHA to skin cancer. Cancer Council+2The Skin Cancer Foundation+2

• In 2020, the EU Scientific Committee on Consumer Safety reviewed DHA in fake tan and concluded it’s not a health risk at cosmetic use levels, while continuing to monitor new data. Cancer Research UK

• By contrast, UV tanning (sunbeds/sunbaking) is a proven risk factor for all types of skin cancer. If you want colour, sunless is the smart route. The Skin Cancer Foundation

The real caveat: mists and inhalation

Regulators have approved DHA for external use on the skin. They have not approved “all-over” spray applications for exposure to eyes, lips, mucous membranes or internal use, because avoiding inhalation in booths/mists can be tricky. The practical takeaway: protect airways and eyes during a spray tan. U.S. Food and Drug Administration

Dermatology reviews echo this: DHA’s risk concern is inhalation, not topical use. Use professional precautions and ventilation. JAAD

Pregnancy, sensitive skin & allergies

Topical DHA doesn’t typically penetrate beyond the dead surface layer and is generally considered safe; still, every skin is unique. If you’re pregnant, breastfeeding, asthmatic, or very sensitive, request extra protection (nose filters/mask, eye shields) and do a patch test first. Cleveland Clinic

Reminder: A spray tan is not SPF. Keep using broad-spectrum sunscreen daily. TIME
