The main effective substance of the self-tanning fluid is dihydroxyacetone (DHA) – an ingredient of natural origin made of glycerine, sugar beet or sugar cane with the ECOCERT and Nature certificates. 

DHA does not penetrate deeper than the outer layer of the skin (stratum corneum), where it reacts with various amino acids of keratin protein, which is the main component of the skin surface, and creates tanned golden appearance. The shade of “tan” is influenced by the composition of amino acids, which is individual. Proportion of amino acids is different in each of us: some amino acids react with DHA and create brown colour, others reach yellow or orange shade, that is why the tanning effect is not identical. Such tanning” lasts shorter (3-5 days) than regular sun tanning, because it is formed in the outermost cornified layer of the skin, which constantly peels. 

It is perfectly safe and healthy unlike intense outdoor exposure to UV radiation or sunbed tanning.
