Here is the short version: exfoliate 24 hours before your appointment, shave or wax at least 12 hours out, shower at least 4 hours before you arrive, and come in with completely bare skin - no lotion, deodorant, makeup, or perfume. Skip Dove, Caress, and other moisturizing bar soaps for a couple of days, and wear loose, dark clothing to your appointment. Do those things and your tan develops evenly and lasts the full 7 to 10 days. Below is the why behind each step, broken down by timeline.
Why prep matters more than people think
An airbrush tan is a chemical reaction, not a coat of paint. DHA, the active ingredient (derived from sugar cane and approved by the FDA for external cosmetic use since 1977), reacts with the amino acids in the outermost layer of your skin. Anything sitting on that layer - dead cells, oil, lotion residue, deodorant - either blocks the reaction or changes how it develops. Uneven surface means uneven color. So prep is not busywork; it is you controlling the canvas.
48 hours out
- Switch to a clarifying body wash. Retire the Dove, Caress, or any "moisturizing" bar soap now (more on why below). A basic, non-moisturizing gel wash is perfect.
- Do your nails, brows, and facials now. Any beauty service that involves scrubbing, steaming, or waxing your skin should happen before your tan, never after. Same goes for spa pedicures - the soak and scrub will strip fresh color from your feet and ankles.
- Plan your calendar. Book your tan so you can stay dry for 4 to 8 hours afterward. No gym, no pool, no rain-soaked soccer sidelines while the color develops.
24 hours out
- Exfoliate head to toe. This is the single most important step. Use a scrub or exfoliating mitt and pay extra attention to elbows, knees, ankles, and heels - the spots where dead skin stacks up and grabs extra color. Exfoliating a full day ahead gives your skin time to settle so the DHA reacts with fresh, even skin instead of a patchwork of old and new cells.
- Shave or wax (at least 12 hours before). Hair removal opens your pores and leaves a light film from razors and wax strips. Give your skin 12+ hours to close back up, or the solution can settle into open pores and leave tiny dark dots. Waxing is even harsher, so if you wax, earlier is better.
- Hydrate normally tonight, then stop. A light lotion the night before is fine. The cutoff is the morning of your appointment.
Day of your appointment
- Shower at least 4 hours before your appointment time, using that plain, non-moisturizing wash. This clears the surface without leaving your skin damp or freshly stripped at spray time.
- Nothing on your skin. Nothing. No lotion, no body oil, no deodorant, no makeup, no perfume. Every one of those leaves a residue that acts like a raincoat between the solution and your skin. Deodorant is the classic culprit - it can turn underarms green-tinged or leave a pale patch where the tan never took.
- Dress the part. Loose, dark clothing and loose footwear (flip-flops or slides are ideal). Tight waistbands, bra straps, and snug sleeves press lines into developing color; light fabrics can pick up cosmetic bronzer before your first rinse.
- Remove jewelry before you arrive, including rings and watches, so nothing shields a stripe of skin.
Why the bar soap warning?
Moisturizing bar soaps like Dove and Caress are engineered to deposit a layer of surfactants and emollients on your skin - that "soft feel" after you rinse is literally product left behind. That film changes your skin's surface pH and creates a barrier the DHA cannot fully penetrate, which is a recipe for splotchy, fast-fading color. It is the most common prep mistake we see, because it does not feel like putting anything on your skin. For the two days before your tan, a simple clarifying wash keeps the canvas clean.
Walking in the door at Soleil
Here is the checklist for the final hour: skin bare and dry, hair manageable (we provide hair caps), loose dark outfit, jewelry off. That is genuinely it. We provide disposable undergarments, hair caps, and sticky feet, and your artist custom-blends your solution on the spot after a quick consult about your skin tone and occasion. The appointment takes 20 to 30 minutes, and then your only job is to stay dry while the color develops over the next 4 to 8 hours.
Once you are sprayed, the game shifts from prep to preservation - our guide to making your spray tan last longer covers the aftercare side, and the full rundown of both lives on our prep and aftercare page.
