How Does an Automated Sunless Tanning Booth Work?

If you've only ever had a hand-applied spray tan, stepping into an automated booth for the first time raises a few obvious questions: what's actually spraying you, how long does it take, and is it as even as having a technician do it by hand? Here's what's really happening inside.

What's actually happening inside the booth

Once you're in position, sensors and timed nozzles apply a fine, even mist of tanning solution from multiple angles. Our heated VersaSpa Pro booth warms the solution first, which helps it go on more evenly and dry faster than a room-temperature spray. Our automated Norvell booth works on the same principle without the heated step, and lets you build color light to dark depending on what you choose. Because the nozzles are fixed and timed rather than hand-guided, coverage is very consistent guest to guest — the tradeoff is that a technician can still out-perform a booth on contouring or touching up a specific problem area.

How it compares to a hand-applied spray tan

Both use the same active ingredient, DHA, which reacts with amino acids in the outer layer of skin to produce color — it's a cosmetic reaction, not a dye or a stain sitting on top of skin. According to the FDA, DHA is an approved color additive for external use, though it's restricted from the eyes, lips and mucous membranes — which is exactly why nose plugs and eye protection are standard in every booth session. The difference between a booth and a technician is entirely in the application: a booth is faster and more hands-off, while a technician can customize color depth and blend around hands and feet.

Safety and aftercare basics

• DHA is for external use only. Nose plugs and eye protection during the session, plus salon ventilation, are standard precautions, not optional extras.
• Exfoliate beforehand. Dead skin cells absorb DHA unevenly, so a shower and light exfoliation the day of your appointment helps color go on smoothly.
• Wait before showering after. Most solutions need a few hours to fully develop before your first rinse — your salon will tell you the exact window for what they use.
• Moisturize daily. Well-hydrated skin fades more evenly and holds color longer.

The bottom line

An automated booth is a fast, consistent, UV-free way to get color, and it's a great fit if you want a quick appointment without back-and-forth with a technician. If you want more customization, like deeper color in specific areas or help blending hands and feet, a hand-applied spray tan is still worth asking about.

Frequently asked questions

Is an automated sunless booth the same as a spray tan?

They use the same DHA-based solution, but a booth applies it through automated nozzles on a timed cycle, while a hand-applied spray tan is customized in real time by a technician. Booths are faster and more consistent; technicians can better handle contouring and problem areas.

How long does a sunless booth session take?

The spray cycle itself typically runs 30 to 90 seconds, with the full appointment including prep and drying usually taking 10 to 15 minutes.

Is sunless tanning safe?

DHA, the active tanning ingredient, is FDA-approved for external use. The main precaution is avoiding inhalation and eye contact, which is why booths use nose plugs, eye protection and proper ventilation.

Do automated sunless booths use UV light?

No. Automated sunless booths use a cosmetic spray solution, not UV light, so there's no UV exposure or burn risk involved in the process itself.

How long does a sunless tan last?

Most sunless tans last 5 to 10 days, depending on skin type, aftercare and how often you shower or exfoliate. Moisturizing daily helps extend it.
