DHA is a natural substance derived from the bioconversion of glycerol extracted from Palm or Rapeseed Oil
DHA is also present in the human body. As a consequence, the risk of an allergic response is very low. The result of using DHA is a natural looking brown or golden hue to the skin, without exposure to the sun. The induced tan provides photo-protection against UVA radiation.
To use, dissolve in a little cold water and then add while the product is under 40°C.
