What are DHA (Dihydroxyacetone) and Erythrulose?

DHA (Dihydroxyacetone) is the primary self-tanning agent in all sunless tanning products. Derived from plant-based sugars, it reacts with amino acids in the outer layer of your skin to produce a natural-looking tan. This process, known as the Maillard reaction, develops color within 4-8 hours and typically lasts 5-7 days, depending on your skin's natural exfoliation cycle and aftercare. DHA is the cornerstone of sunless tanning, delivering safe, effective, and UV-free results.

Erythrulose is another sugar-derived tanning agent often used in combination with DHA. It develops color more gradually over 24-48 hours and helps create a deeper, more even tan with a smoother fade. However, erythrulose is not used in all products due to its slower development time and its limitations as a standalone tanning ingredient. While it can produce a light tan on its own, it is far more effective when paired with DHA, as this combination enhances the overall depth, longevity, and appearance of the tan.

At AYU Sunless, we use the best of both ingredients to create innovative, skin care-infused tanning solutions that honor your skin's natural radiance while delivering a beautiful, long-lasting tan.

What are bronzers (color guide) and and How Do They Work in Sunless Tanning Products?

Bronzers, also known as color guides, provide an instant tan-like appearance and help ensure smooth, even application in sunless tanning products. They serve as a visual aid, allowing spray tan artists and self-tanners to see where the product has been applied, minimizing streaks or missed areas.

Why are bronzers important in sunless tanning?

  • Instant Color for Flawless Application – Bronzers offer immediate color, helping users achieve an even tan and preventing uneven patches.
  • Temporary Glow While DHA Develops – Since Dihydroxyacetone (DHA), the active tanning ingredient, takes several hours to react with the skin fully, bronzers provide a temporary glow until the tan fully develops. Once rinsed, the bronzer washes away, revealing the true DHA-developed tan underneath.

Types of bronzers used in sunless tanner

  • FD&C/D&C Dyes – Custom-blended water-soluble colors such as D&C Red No. 40, FD&C Yellow No. 6, FD&C Blue No. 1 to create a natural bronze hue.
  • Caramel – A warm-toned natural colorant that blends effortlessly for a smooth, even look.
  • Erythrulose – Sometimes combined with DHA for a gradual color boost and a more natural fade.

Bronzers ensure that your sunless tanning application is seamless, making them an essential component of high-quality sunless tanning products.

How long does the color of AYU sunless tanning products last?

The color from AYU sunless tanning products usually lasts 7 to 10 days. To get perfect results follow the instructions for “before and after care” listed on the SunlessSmart information page. Exfoliation and moisturizing is the main key in maintaining a smooth, even, and radiant tan.

What is the difference between “Clear Solution” and “With Bronzer (brown) Solution”?

Both solutions are sunless tanning solutions that contain DHA and/or Erythrulose. The Clear Solution is colorless and is either crystal clear or milky white depending on which AYU solution you are applying. The Clear Solution is good for facial application due to sensitive skin, or when clients are going to wear a white dress occasions such as weddings. Most people prefer to be sprayed with clear solution to avoid transferring unwanted color onto their expensive dress. Caution and practice is suggested before spraying with the Clear Solution.

The Bronzer solution contains FD&C or D&C colors. The need for the Bronzer Solution is that it helps the technician perform an even application that results in smooth, glowing tan; also, it aids in an “instant gratification” tan appearance with the first application. Once the DHA and Erythrulose tan develops after 4 to 8 hours, the client can wash off the bronzer and reveal a radiant, beautiful tan.

How do AYU products work with sensitive skin?

All AYU products are carefully formulated to be gentle, even on sensitive skin. Though it is recommended when trying any new product that a 24-hour test is performed on the back of your neck before applying on the face or body.

Do AYU sunless tanning products and bronzers provide protection from the sun?

No, AYU sunless tanning products and bronzers do not provide protection from sun. All of the labels on our sunless tanning products contain the below warning:

"Warning--This product does not contain a sunscreen and does not protect against sunburn. Repeated exposure of unprotected skin while tanning may increase the risk of skin aging, skin cancer, and other harmful effects to the skin even if you do not burn."

What % DHA solution is right for me?

6% DHA is perfect for the very fair skinned clients, or those with very dry or aged skin or fading problems; also those who are extremely sensitive to sun, as well as the client who prefers a lighter softer touch of color. This is also a recommended product for a mid-week touch-up application if needed. Sensitive skin type 1 (light hair, fair skin and freckles usually burns in sun).

8% DHA is for the average client. It creates a nice medium tan depth, with optimal fading, without creating the “over baked effect”. The appropriate solution for light to medium skin tones, though it can also be applied thinner for your fairest clients. 8% DHA is versatile for a wide range of skin types. Sensitive to medium skin type 1-2 (who will tan very little in sun but burns very easily, light hair, fair skin).

10% DHA is the “enhanced” version of our popular 8% product, just slightly darker. Appropriate for all medium skinned clients and ever some of your darker skinned clients. This is a superior mid-level product, for the client who requires more depth of color, without sacrificing smooth fade-off. It is great for people who burn moderately but tan gradually and achieve medium tan in sun, most skin type 2,3 and 4 will achieve beautiful tan with 10% DHA AYU sunless tanners.

12% DHA is the darkest solution in our line up. Perfect for the client with darker skin tones, or darker skin coloration from a UV based tan. This product is an intense product, for creating lots of deep color, but it may not fade as smoothly on the fairest skin types. Use caution on hands and feet and dry skin areas. This is good for skin type 5 and 6 who minimally burns in sun and tans deeply.

How long does a spay tan last?

The duration of a spray tan can vary from person to person, typically lasting between 7 to 10 days. It's important to note that the tan gradually fades over time rather than disappearing suddenly. The natural exfoliation process of the skin causes the tan to lighten gradually.

Spray tans offer a convenient and safe alternative to sun exposure for achieving a beautiful bronzed glow. However, one common question among spray tan enthusiasts is, "How long does a spray tan last?"

For a longer-lasting spray tan, there are several key factors to consider:

  • Skin Preparation: Properly exfoliating your skin before the spray tan helps remove dead skin cells and creates a fresh canvas for the tan. Clean and clear skin allows the spray tan solution to adhere better to the skin.
  • Tanning Solution and Technique: The quality of the tanning solution used and the expertise of the spray tan professional are essential factors. Higher-quality solutions and skilled application techniques often result in longer-lasting tans.
  • Skin Type and Maintenance: Your skin type and how well you care for your skin post tan can affect the lifespan of the tan. Dehydrated or dry skin tends to shed more rapidly, leading to faster fading. Consistently moisturizing with spray tan-safe products and avoiding excessive exfoliation can help maintain the tan's vibrancy.
  • Activities and Environmental Factors: Swimming in chlorinated pools or spending extended periods in saltwater can accelerate tan fading. Additionally, excessive sweating,   especially during intense workouts, can impact the longevity of the tan.
  • Patience during Development: Following the recommended development time provided by your spray tan professional is crucial. Rinsing off the tan too early can diminish its effectiveness. Remember that the color will deepen over time if you opt for a rapid tan solution.

By being mindful of these factors and taking appropriate steps, you can help extend how long your spray tan lasts and enjoy a beautiful, long-lasting glow.
