Technically you can apply regular body lotion before a tanning bed session, but it’s not a good idea — and for a few reasons that go beyond just getting a suboptimal tan. Regular lotion isn’t formulated for tanning bed conditions, it won’t give your skin the hydration and UV-optimising benefits that purpose-built tanning bed lotion provides, and certain types can actually damage the acrylic shields on the bed itself.
If you’ve forgotten your tanning lotion or want to understand what makes the difference, here’s a clear breakdown of why it matters and what your best alternatives are.
Key Takeaways
- Regular body lotion can interfere with UV penetration in a tanning bed, particularly if it’s thick or cream-based — oils are less disruptive.
- Any regular lotion with SPF actively blocks UV rays and will significantly reduce or eliminate your tan — never use an SPF lotion in a tanning bed.
- Certain lotions and oils can cause micro-crazing (fine surface cracking) of tanning bed acrylic shields over time — many salons prohibit non-specialist products for this reason.
- Tanning bed lotions contain active ingredients — bronzers, melanin stimulators, and skin-conditioning agents — that regular lotions simply don’t include.
- If you don’t have tanning lotion, a thin natural oil like coconut or olive oil is a better emergency alternative than a thick cream-based lotion.
- Moisturising well after your session with an after-tan lotion is just as important as what you apply before.
Why Regular Lotion Isn’t Ideal for Tanning Beds
It may reduce UV penetration
Tanning beds work by delivering UV rays to your skin to stimulate melanin production. Any product applied to the skin’s surface can, to varying degrees, act as a barrier between the UV and your skin. Thick, heavy creams are the most problematic — the denser the product, the more it can interfere with the UV reaching the skin evenly, which can lead to patchy or uneven development.
Thinner, oil-based products are much less disruptive, which is why most tanning bed lotions are formulated as lightweight oils or light emulsions rather than thick creams. If you do use a regular lotion, a thin oil-based option causes less interference than a heavy cream.
SPF in regular lotion actively blocks your tan
Many regular body and face moisturisers contain SPF — and this is a significant problem in a tanning bed context. Sunscreen actively blocks UV radiation. Applying an SPF 30 lotion before a tanning bed session means roughly 97% of UVB is being blocked before it reaches your skin, which essentially defeats the entire purpose of the session and wastes your money.
Always check the label of any lotion you’re considering using before a tanning bed session. If it contains any sunscreen ingredient or SPF rating, don’t use it.
It can damage the tanning bed’s acrylic shields
This is the most practical concern that most people don’t know about. Tanning bed bulbs are covered by clear acrylic shields that protect users and direct UV evenly. Certain lotion and oil ingredients — particularly heavier petroleum derivatives and some plant oils — can cause a chemical reaction with acrylic called micro-crazing: fine surface cracking that clouds the acrylic, reduces UV transmission, and is expensive to replace.
This is why most tanning salons have policies restricting the use of non-specialist products. Some will ask you to declare what you’ve applied before getting in. Beyond salon rules, damaging acrylic on a home tanning bed is a real cost consideration. Pure tanning lotions are formulated to be acrylic-safe; most regular lotions are not specifically tested for this.
It doesn’t contain the active ingredients that help
Tanning bed lotions are formulated specifically to work with UV exposure — they contain ingredients that regular lotions simply don’t. These include tyrosine (an amino acid that supports melanin production), bronzers that add immediate colour, melanin-stimulating compounds, and skin conditioners that are stable under UV and heat conditions. Regular lotion provides moisture, but none of the UV-optimising function that makes tanning bed lotion worth using. More on how these ingredients work is covered in our guide on what tanning lotion actually does.
What to Use If You Don’t Have Tanning Bed Lotion
If you’re at a session without your usual product and want something on your skin, here are your options in order of preference:
A purpose-built tanning accelerator or lotion. Many salons sell or stock tanning lotions — ask at the desk before your session. This is always the best option. You can also find a good range of options in our guide to the best tan accelerators.
A thin natural oil. Coconut oil or olive oil applied in a thin, even layer are better alternatives than a thick regular cream. They don’t contain UV-blocking agents, provide some skin conditioning, and are less likely to cause uneven UV penetration than denser lotions. Use sparingly — a thin coat, not a thick application — to reduce the risk of acrylic contact and to avoid excess product pooling on the bed surface.
Nothing at all. Going into a tanning bed with completely clean, dry skin is a better option than using a thick SPF-containing lotion. You’ll want to moisturise well with an after-tan lotion once your session ends, but leaving skin product-free during the session is preferable to actively blocking UV.
The Importance of After-Session Moisturising
Whatever you use before a tanning bed session, moisturising afterward is essential. UV exposure dries the skin, and dry skin sheds faster — which means a tan that fades more quickly and less evenly. Applying a good after-tan lotion or body moisturiser immediately after your shower following a session locks in moisture, helps the tan develop properly overnight, and keeps the color looking even for longer.
This step is often undervalued, but it’s just as important for tan longevity as what you apply before getting in the bed.
Frequently Asked Questions
Can you use regular lotion in a tanning bed?
Technically yes, but it isn’t recommended. Regular lotion isn’t formulated for tanning bed use, may interfere with UV penetration, and certain types can damage the bed’s acrylic shields. If it contains SPF, it will actively block UV and reduce your tan. A purpose-built tanning bed lotion, or a thin natural oil as a fallback, are both better choices.
Can I use regular lotion to tan outside?
The same principle applies outdoors — a regular SPF-containing lotion will reduce how quickly you tan, and thick creams may create an uneven surface. For outdoor tanning, a dedicated tan accelerator or tanning oil is more effective. Regular lotion is fine for moisturising after tanning, once you’re done with your session.
Can you use tanning oil in a tanning bed?
Tanning oil is a better option than regular lotion for a tanning bed session, but check that it’s specifically formulated for indoor tanning use. Some generic plant oils can damage acrylic shields over time. Purpose-built tanning oils for indoor use are acrylic-safe and give you the benefits of oil application without the equipment risk. More detail on this is in our guide to using tanning oil correctly.
Can you tan without tanning lotion?
Yes — tanning lotion isn’t mandatory. You’ll still tan without it, though the result may be less even and your skin will dry out faster from the UV exposure. Tanning lotion enhances the session and helps maintain skin condition; it doesn’t make tanning possible on its own.
Do you need special tanning lotion for tanning beds?
Not strictly, but purpose-built tanning bed lotion meaningfully improves the experience. It speeds up the tanning process, keeps skin hydrated under UV conditions, helps the color develop evenly, and is formulated to be safe on tanning bed acrylics. It’s also significantly cheaper per session than the cost difference would suggest — a good bottle lasts many sessions.
What happens if you use regular lotion with SPF in a tanning bed?
The sunscreen actively blocks UV, which means a significant portion — potentially 93 to 97% — of the UV that the tanning bed produces won’t reach your skin. Your tan will be dramatically reduced or won’t develop at all. Never use an SPF product before a tanning bed session.
Final Thoughts
Regular lotion in a tanning bed is at best a neutral choice and at worst actively counterproductive. SPF-containing lotions are a particular problem and should never be used before a session. Thick cream-based lotions can interfere with UV penetration and potentially damage the bed’s acrylic surface.
If you’ve forgotten your tanning lotion, a thin coat of natural oil is the best immediate alternative, or simply go in with clean skin and moisturise thoroughly after your session. Longer term, investing in a proper tanning bed lotion is worth it — the results are genuinely better, and your skin will be in better condition for it.
