What Makes Sunless Tanning Work?

Let’s Talk DHA!
Sunless tanning products—like the professional-grade solutions from Nuda Canada—deliver that beautiful bronzed glow thanks to a powerhouse ingredient called DHA (dihydroxyacetone).
DHA is a colorless compound that reacts with the amino acids on the outer layer of your skin, creating a natural-looking tan without the need for UV exposure.
DHA is non-toxic, and your skin doesn’t absorb it into the body. It only affects the top layer of dead skin cells, which naturally shed every few days. That’s why a sunless tan typically lasts 7 to 10 days, depending on your skin type, preparation and aftercare routine.
Originally discovered in the 1920s by German scientists, DHA made its debut in tanning products like Coppertone’s QT in the 1960s. However, early formulas were known to cause an orange tint. Thanks to decades of innovation, modern formulas now create flawless, sun-kissed results with natural fading.
In 1973, the FDA approved DHA for use in cosmetic tanning products—making it the only active ingredient officially recognized for sunless tanning. Today’s professional-grade products contain 1% to 15% DHA, with higher concentrations delivering a deeper tan.
The solutions typically fall within the 5% to 15% DHA range—ideal for customized tanning based on skin tone and desired results.
Applied with professional spray tan techniques, these tans develop beautifully and won’t sweat off or rinse away with water. With proper care, you can enjoy a radiant glow for more than a week.
As awareness grows about the risks of UV damage and skin cancer, DHA-based sunless tanning is the safe, effective alternative to traditional tanning beds. Whether you’re a salon professional, mobile technician, or beauty boss looking to offer premium results, Nuda Canada has you covered.
