What is DHA?


Have you ever wondered how spray tan and self tan makes your skin, well, tan? The ‘magic’ ingredient is DHA - Dihyroxyacetone. It’s a type of sugar derived from plants, often beets. The DHA interacts with the proteins in the top layers of your skin to produce the tan colour, without the need for UV light exposure to initiate the reaction. This is called the ‘Mallaird’ reaction during which the sugars in DHA react with keratinocyte proteins causing oxidation of the sugar derivates.

DHA does not generally cause allergic reactions in the skin but often spray tans are formulated with lots of chemicals such as preservatives which people can react to. All blushtan solution products are made with the absolute minimal ingredients, including no fragrances and no alcohol, so it’s skin friendly while giving you a gorgeous glow.
