Fast-acting tanning ingredient

Dihydroxyacetone (DHA), a three carbon sugar derived from biotechnology, contains a carbonyl group (R-CHO) in its structure. 

This carbonyl group can undergo a Maillard reaction (carbonyl amine condensation, like the reaction that browns food when cooking) with the free amino groups (-NH₂) of keratin in the stratum corneum of the skin. 

The reaction produces brownish melanoidin pigments that deposit on the surface of the stratum corneum, thereby giving the skin a natural tan appearance. 

Unlike UV tanning, it does not damage the DNA of skin cells or require exposure to harmful UV radiation.

Due to its low molecular weight, DHA can initiate the Maillard reaction and take effect at a faster rate. 

The following results were observed after a single application of a 5% UNIBIO_DHA gel product.

The color develops gradually over a period of 4 to 6 hours after application. The 'tan' typically lasts 6 days before it begins to fade. 

It fades naturally as the skin sheds its dead cells, which is why exfoliation is often recommended before application to ensure an even fade.
