Although it's a fairly low statistic, about two in every 100,000 people are allergic to DHA.
The active ingredient of DHA reacts with the cells in the outermost layer of your skin, producing a brown pigment, but the DHA isn't absorbed into the blood stream. Fake tan can dry out your skin, so ensure you use plenty of moisturiser – and if you get a rash, don't use the product again.

Dihydroxyacetone (DHA), the active substance in sunless tanning lotions reacts with the amino groups of proteins to form a brown-colored complex. Furthermore, DHA caused DNA damage as revealed by the alkaline comet assay. Preincubation with antioxidants prevented the formation of DNA strand breaks.
