If you have ever stepped into a spray tan booth and wondered exactly what is in the fine mist settling onto your skin, this is a great question to explore. Understanding what is spray tan made of helps you feel confident stepping into the booth and walking out with a glow you love.
At SolShine Tanning & Wellness, we use the Mystic Tan Unity, one of the most technologically advanced spray tan booths on the market, so knowing what is in the solution is just the beginning of understanding why the results look so natural. Let’s break it down, ingredient by ingredient.
The Key Active Ingredient: DHA (Dihydroxyacetone)
When it comes to what is spray tan made of, one ingredient sits at the center of everything: DHA, or dihydroxyacetone.
DHA is a simple, naturally derived sugar compound, most commonly sourced from sugar beets or sugar cane. It has been approved by the FDA for external use on the skin for decades, and it is the active ingredient responsible for giving you that sun-kissed color.
Here is how it works: when DHA contacts the outermost layer of your skin, it triggers a chemical reaction with the amino acids present in your dead skin cells. This process, known as the Maillard reaction, produces brown-colored compounds called melanoidins. These compounds sit on the surface of your skin and create the appearance of a tan. No UV rays, no sun exposure, just a targeted reaction in the very top layer of your skin.
The color typically begins to develop within two to four hours and reaches its full depth within 24 hours. Because it affects only the outermost layer of dead skin cells, it fades naturally as those cells shed over about a week.
Why Erythrulose Matters, Too
Many professional-grade tanning solutions pair DHA with a second active ingredient in spray tans called erythrulose. Like DHA, erythrulose is a naturally derived sugar, but it develops color more slowly and produces a slightly different tone.
When erythrulose is used alongside DHA, the two ingredients work together to create a more even, longer-lasting result. Erythrulose tends to produce warmer, more golden tones, which is part of why a quality sunless tanning product delivers a result that looks natural rather than flat or artificial.
If you have ever had a spray tan that faded unevenly or turned patchy too quickly, the formulation of the tanning solution itself often plays a role. A well-balanced blend of DHA and erythrulose helps the color develop more uniformly and wear off more gracefully.
What Else Is in the Tanning Solution?
Beyond the active tanning ingredients, a quality spray tan formulation includes a range of supporting components that affect how your skin looks and feels before, during, and after your session.
Moisturizers and hydrators. Your skin absorbs tanning solution more evenly when it is well-hydrated. Most professional-grade solutions include ingredients like aloe vera, glycerin, or hyaluronic acid to condition your skin during the session and help the tan last longer.
Bronzers. Many solutions contain cosmetic bronzers that give you an immediate color boost right after your session, before the DHA has fully developed. This instant color helps you preview the depth of your result and avoid any streaks or missed areas.
pH balancers. The pH of the solution affects how well the DHA reacts with your skin and how evenly the color develops. A properly balanced formula helps ensure a consistent result across all skin tones.
Fragrance components. Spray tans have a recognizable scent that comes from the chemical reaction between DHA and your skin. Quality tanning solutions use carefully selected fragrance ingredients to minimize or neutralize that odor without irritating sensitive skin.
Skin-nourishing additives. Depending on the formulation, you may also find vitamins, antioxidants, and botanical extracts designed to support skin health and give your tan a healthy-looking finish.
Are Spray Tan Ingredients Safe?
This is where the science offers some reassurance. The core ingredient, DHA (dihydroxyacetone), has a long safety record for topical use and does not penetrate beyond the outermost layer of your skin. It does not interact with your living cells, your bloodstream, or your melanin the way UV exposure does.
That said, spray tanning does involve a fine mist during application, which is one reason proper ventilation and booth design matter. At SolShine Tanning & Wellness, your sunless tanning session takes place in the Mystic Tan Unity, a stand-up automated booth built with MagneTan Spray technology for precise, even coverage from head to toe. The booth is engineered to deliver a consistent application while minimizing airborne mist exposure, making it a cleaner, more controlled experience than a handheld spray gun.
If you have known sensitivities or allergies, it is always a good idea to ask one of our team members about the specific solution being used. We are here to walk you through every ingredient in the products we use so you can make the best choice for your skin.
What to Look for in a Quality Spray Tan Product
Not all sunless tanning products are created equal. Whether you are visiting a salon or browsing a tanning lotion for home use, here is what separates a quality product from one that leaves you looking uneven or overly orange.
Look for a formula that balances DHA and erythrulose for a more natural, lasting tone. Check that the solution includes moisturizing ingredients, since dry skin develops color unevenly and fades faster. A well-formulated product should also have a mild, pleasant scent and be matched to your skin tone and tanning goals.
At SolShine Tanning & Wellness, the Mystic Tan Unity system lets you personalize your session before you even step into the booth. Using the Mystic App, you can choose from 12 spray levels, select a bronzer that complements your skin tone for instant color gratification, and pick up to two scents to keep the experience enjoyable from start to finish. Directly following your spray tan, the booth delivers a moisturizing beauty application that hydrates and softens your skin, helping your tan look fresh for days.
