Dihydroxyacetone, a naturally occurring compound, also used in medicine. In cosmetics, it is responsible for the rapid appearance of brown skin colour, as it reacts with the stratum corneum proteins of the epidermis. The pigment that is formed in the process of the reaction, a derivative of melanin, gives the skin a brown hue, however, it does not protect against the harmful effects of UV radiation, unlike natural melanin! Bronzing of the skin appears after about 2-4 hours following the application of DHA.
A sugar compound, similar to DHA, but characterized by much greater stability. It works a little more slowly, however, due to the slower penetration through the stratum corneum of the epidermis, it is possible to spread the preparation evenly for a nicer tan.
Referred to as the vitamin of youth, because, like no other, it protects the skin from the harmful effects of free radicals. It inhibits skin aging, reinforces the epidermal barrier, prevents inflammation, strengthens the walls of blood vessels and improves blood circulation in the skin.
One of the more well-known and widely used natural bronzing ingredients. The juglone present in the extract, reacts with the keratin of the epidermis and forms a coloured compound that lends the skin the brown tone of a natural tan. It is characterized by high stability and no streak-forming effect on the skin as well as a stronger and longer-lasting shade of brown than is rendered by DHA.
