Self-tanning products have gained significant popularity as a safer alternative to tanning beds and direct sunlight. For those who desire a beautiful tan without the associated risks, these products seem like the ideal solution. However, it is important to be aware that while most self-tanners are generally safe to use, there are still a few potential health concerns and risks that come with them.
Understanding the Mechanism Behind Self-Tanners
Self-tanning methods, such as spray tans and various sunless tanning products like lotions, creams, and gels, employ colorants to achieve a sun-kissed complexion. One of the most commonly used color additives in modern self-tanners is dihydroxyacetone (DHA). When DHA comes into contact with the skin, it reacts with the dead skin cells, leading to a temporary darkening effect that imitates a natural tan. The intensity of the tan can be adjusted by using different concentrations of DHA, allowing for a range of self-tanners with varying levels of “strength.”
Research on DHA
The study of DHA (Dihydroxyacetone) by medical researchers dates back to the 1920s, but it was not until the 1950s that it gained prominence as a key ingredient in self-tanning products. Over the years, extensive research has been conducted to understand its effects.
Initially, DHA was developed as a substitute for glucose in individuals with diabetes, and studies have shown that oral administration of DHA was well-tolerated. While recent research has raised concerns about the potential DNA damage caused by DHA, it is important to note that these findings are based on concentrations of DHA far exceeding what is typically found in self-tanning products and spray tans.
