Deciding between a tanning bed and a spray tan usually comes down to three practical questions: How long do you want the tan to last? How much are you willing to spend? And how do you feel about exposing your skin to ultraviolet (UV) light? Both options darken the skin, but they work in completely different ways and come with different trade-offs. This guide explains how each method works, what results to expect, the typical costs, and the safety considerations you should weigh before booking.
Short answer: A tanning bed produces a deeper, longer-lasting tan — typically fading over one to two weeks — but it relies on UV radiation, which raises the risk of skin damage and skin cancer. A spray tan is UV-free, fast, and painless, and it lasts roughly five to ten days. If safety is your top priority, a spray tan is generally the better choice. The details below will help you decide either way.
What Is a Tanning Bed?
A tanning bed is a booth lined with lamps that emit ultraviolet radiation. When you lie in the bed for a set number of minutes, the UV light stimulates cells in your skin called melanocytes to produce extra melanin — the pigment that gives skin its color. That pigment is what we see as a tan.
Sessions typically last anywhere from a few minutes to about 20 minutes, depending on the equipment and your skin type. The tan develops over several hours to a day and deepens with repeated sessions. Because the color comes from your own skin, it fades gradually as skin cells naturally turn over, usually over one to two weeks.
Tanning beds generally fall into two categories:
- Low-pressure beds: Emit mostly UVA light with some UVB. Sessions run longer, often 10 to 20 minutes.
- High-pressure beds: Emit mostly UVA with very little UVB. Sessions are shorter, often under 10 minutes.
What Is a Spray Tan?
A spray tan is a cosmetic application rather than a biological response. A technician — or an automated booth — sprays a fine mist of a solution containing dihydroxyacetone (DHA), a simple sugar compound that reacts with the amino acids in the outer layer of dead skin cells. That reaction temporarily darkens the skin’s surface.
Because DHA only affects the outermost layer, the color sits on the skin rather than inside it. The whole session usually takes 10 to 20 minutes, including drying time. Results appear within a few hours and typically last five to ten days, fading as those outer skin cells shed.
Spray tans are available in a few formats:
- Automated booth: A machine sprays you from multiple angles while you stand in a guided pose sequence.
- Custom airbrush: A technician applies the solution by hand, which allows for more even coverage and control.
- At-home options: Self-tanning mists, lotions, and foams use similar ingredients and can be applied at home.
Side-by-Side Comparison
Appearance and longevity
- Tanning bed: A natural, gradual tan that can reach a deep shade with repeated sessions. Lasts one to two weeks and fades evenly.
- Spray tan: An even, immediate-looking color that can be adjusted to your preferred shade. Lasts about five to ten days and fades as the top layer of skin exfoliates.
Cost
- Tanning bed: Single sessions often cost a small fee, and monthly packages can lower the per-session price. Costs add up if you tan regularly to maintain color.
- Spray tan: A single session usually costs more than a single bed session, and custom airbrush applications cost the most. Because the tan is short-lived, frequent touch-ups raise the total cost.
Convenience and maintenance
- Tanning bed: Quick sessions with little preparation. No special aftercare is needed, though results require repeat visits to maintain.
- Spray tan: Requires preparation such as exfoliating and shaving beforehand, plus aftercare like avoiding moisture, tight clothing, and swimming for several hours. It can transfer onto clothing and sheets while developing.
Suitability for different skin tones
- Tanning bed: Results vary widely by skin type. Some people tan easily; others mostly burn. Very fair skin may not tan at all.
- Spray tan: Works on virtually any skin tone. Technicians can adjust the formula’s strength to suit your natural coloring.
Health and Safety Considerations
This is the biggest difference between the two options, and it deserves the most attention.
Tanning bed risks
Tanning beds expose skin to ultraviolet radiation, the same type of radiation linked to skin damage. Health agencies and dermatologists consistently advise against deliberate UV tanning, particularly for people under 18.
- Increased risk of skin cancer, including melanoma
- Premature aging: wrinkles, dark spots, and loss of skin elasticity
- Sunburn, especially with longer or too-frequent sessions
- Eye damage if protective eyewear is not worn
- Weakened immune response in the skin
There is no such thing as a completely safe UV tan. A so-called base tan does not protect you from sunburn — it only indicates that skin damage has already begun.
Spray tan risks
Spray tans do not involve UV radiation, so they do not increase skin cancer risk or cause UV-related aging. However, they are not entirely risk-free.
- DHA is approved for external use on the skin, but inhaling or ingesting the mist should be avoided. Ask for protective nose plugs, lip balm, and eye coverings during the session.
- Some people experience skin irritation, itching, or an allergic reaction to the solution.
- Spray tans offer no sun protection. A common misconception is that a spray tan acts like sunscreen. It does not — you still need sunscreen outdoors.
- Uneven or orange results are possible, especially with automated booths or poor preparation.
Who Should Choose a Tanning Bed
A tanning bed may appeal if you want a darker, longer-lasting tan and you are comfortable accepting the documented risks of UV exposure. It may also suit people who dislike the scent of self-tanning products or the maintenance a spray tan requires.
However, tanning beds are not recommended for anyone who is pregnant, taking medications that increase sun sensitivity, has a personal or family history of skin cancer, has very fair skin, or is under 18. If any of these apply, a spray tan is the better option.
Who Should Choose a Spray Tan
A spray tan is generally the better choice if you want a quick, painless, UV-free result with no risk of burning. It suits people preparing for an event, anyone with fair skin that does not tan well, and anyone who wants to avoid UV exposure altogether.
Choose a spray tan with realistic timing in mind: book it two to three days before your event so the color has fully developed but has not started to fade.
Tips for Getting the Best Results
Whether you choose a bed or a spray, a few habits improve your outcome and reduce problems:
- Know your skin type. Fair skin burns quickly and tans poorly, which affects both options.
- Start conservatively. Shorter sessions reduce the risk of burning in a bed; a lighter spray shade can be built up later.
- Prepare for spray tans. Exfoliate and shave the day before, and arrive with clean, product-free skin.
- Protect your eyes. Wear approved eyewear in a tanning bed and protective coverings during a spray session.
- Use sunscreen outdoors. Neither option replaces sun protection.
- Check your skin. Regularly examine your skin for new or changing moles and see a doctor about anything unusual.
Final Thoughts
Both options deliver a darker look, but they are not equal in safety. A tanning bed gives you a deeper tan that lasts longer, at the cost of UV exposure and the health risks that come with it. A spray tan is UV-free, easy to schedule, and works on nearly every skin tone, but it lasts only about a week and requires some preparation and aftercare.
For most people, a spray tan is the safer and more practical choice. If you still want to use a tanning bed, go in with clear information about the risks and avoid overexposure.
