Self-tanning occurs in the top layers of your skin called the Epidermis. The Epidermis is also made up of layers. The Stratum Corneum (or Horny Layer) is the layer affected by self-tan products. The Natural Sun Original Self-Tan products contain the naturally derived, premium tanning pure agents DHA and Erythulose.
About DHA (Dihydroxyacetone)
Although DHA has been used in self-tans since the 1970’s, it wasn’t until the late 1980’s that cosmetic companies found a way to produce better results (browner, less orange) with DHA. This is attributed to an improved refining process yielding higher quality, more predictable DHA. Natural Sun only uses the most premium pure DHA throughout all our self-tans. Pure DHA interacts with the amino acid- Keratin (more commonly known as ‘dead’ or `cornified` skin cells) that lie in the top layers of your skin (the Stratum Corneum or Horny Layer). This tan develops rapidly, but is also most temporary as your skin cells are worn away.
Both DHA and Erythrulose do the same thing – they react with Amino Acids to turn your skin brown. Eruthrulose is a Ketosis which also reacts with the amino acid – Keratin. This reaction leads to the formulation of brownish coloured polmers called Melanoids. Erythulose used on its own has to be applied daily, and it never develops a dark tan. However, when combined with DHA, they work together to reduce streaking and miscolouring for a natural looking tan. They also make your tan last longer and fade perfectly evenly for a continuously natural appearance.
Cosmetic Guide Colour
Natural Sun Self-Tans also contain a guide colour. This assists your application, showing you where you have applied the self-tan. It also gives your skin an instant golden sun-kissed look. However, this is simply cosmetic and washes off.
