Dihydroxyacetone

What is Dihydroxyacetone?

Dihydroxyacetone (DHA) is a colorless sugar commonly used in self-tanners. When applied to the skin, DHA reacts with amino acids in the outer layer, resulting in a temporary bronzed color. This “tan” typically develops within a few hours and can last up to a week, making DHA a popular choice for achieving a sunless tan without UV exposure.


Why do I have an intolerance?

Intolerance to DHA may manifest as skin irritation, redness, or dryness. This is often due to sensitivities to the chemical reaction it creates on the skin. Additionally, some individuals find the scent of DHA unpleasant, especially as the tan develops.


What can I do about it?

If you experience intolerance to DHA, consider alternatives like erythrulose-based self-tanners or tinted body lotions, which may be gentler on sensitive skin. Opt for gradual tanning lotions with a lower DHA concentration to reduce the likelihood of irritation. Always perform a small test application if you have sensitive skin to confirm compatibility with the product.
