Myths and Facts About DHA

Must read

It is very important that consumers recognize how products work- their basic functions, mechanisms of action, and the side effects, if there are any. In the case of sunless tanning, no other ingredient gets more attention than dihydroxyacetone or DHA. Among all the ingredients involved in the manufacturing of sunless tanning systems, it gets more scrutiny from those who believe that natural sun bathing is still the best way to go. In this article, we will shed light on everything that you need to know about DHA! By supplementing readers with myths and facts, you will most assuredly know that sunless tanning is still the better alternative to get a beautiful and glowing tanned skin!

What is DHA?

Dihydroxyacetone (DHA) or glycerone was discovered by accident. In the 1920s, DHA was used as a coloring agent for patients who are about to undergo X-ray diagnostic procedures. Scientists have noticed that accidental spillage of DHA results in brownish skin discolorations. It was also used as a medication for children suffering from glycogen storage disease.

DHA used in self tanners should not be confused with DHA found in Omega-3 fatty acids. It was in the 1960s that DHA was being marketed as one of the key ingredients of sunless tanning solutions. In its early years, sunless tanners were not so popular as men and women experienced undesirable results which mainly involved excessive orange stain that left the skin. Technological advancements have allowed manufacturers to improve on their DHA formula, thus most self tanning lotions nowadays leave a more desirable tan or brown color after application. The natural coloring of sunless tanners of recent years makes the most desirable option among men and women who would like to avoid sun bathing altogether.

Due to the high level of safety and efficient of DHA, majority of tanning solutions in the market increase the concentration to make them more appealing, especially to those who desire to have sun kissed skin all year round. Doctors recommend consumers to purchase DHA which contains 3% up to 15% of DHA only.
