The sciencey bit: basically, the active ingredient that makes any self tanner work is dihydroxyacetone or DHA for short. It's essentially a type of sugar and when applied to your skin, reacts with the top layer to brown it in a similar way that food browns when it's left exposed to air. Since it is just the top layer of skin that the DHA reacts with, it lasts for just a couple of days until that layer of skin has been washed away. Gradual tanners have a much lower concentration of this ingredient than regular fake-tan which makes the effect more subtle and allows you to build up the tan gradually.




The product was sent to me to try but as usual this does not affect my opinion in any way.
