What does DHA in sunless tanning products do?

• A. It protects skin from UV rays
• B. It provides color to the skin
• C. It hydrates the skin
• D. It exfoliates the skin

Answer: (B)

DHA, or dihydroxyacetone, is the active ingredient in many sunless tanning products. It works by interacting with the amino acids in the outer layer of the skin to create a browning effect, which results in a tanned appearance. This reaction typically begins within a few hours of application and can last from several days to a week, depending on the specific product and individual skin characteristics. The ability of DHA to provide color to the skin is a primary reason for its use in cosmetic tanning products. Unlike traditional tanning methods that involve UV exposure, which can damage skin and increase the risk of skin cancer, DHA offers a safer alternative that allows individuals to achieve a tanned look without the harmful effects of UV radiation. Other options, while related to skin care routines, do not accurately describe the function of DHA. For instance, DHA does not protect against UV rays, hydrate, or exfoliate the skin. Instead, its primary and well-established role is providing a temporary color change. Understanding this can be beneficial for anyone looking to educate clients or consumers about the effects and benefits of sunless tanning products.
