As consumers are increasingly aware of the negative health effects of sunbathing and tanning beds, there is a high demand for safe alternatives to sunbathing. Erythrulose is a natural tanning ingredient, which provides a more real, uniform and lasting tanning effect. Because of its smooth tanning function, it is a very useful progressive tanning product. It can be well combined with ActiBiso-DHA, which are two types of classic self tanning agent and progressive tanning agent.

Erythrulose is a kind of natural tanning agent. Through Maillard reaction, it reacts with the protein peptide amino group on the skin surface to form a brown polymer product which combines directly with the skin surface (cuticle). Compared with 1,3-Dihydroxyacetone, Erythrulose provides a more natural and true brown color with longer duration and more stable formula. • partner with DHA. Erythrulose improves the properties of self tanning products, such as less streaks, a more natural color, which avoids skin dryness and irritation. Erythritol can lead to a permanent tanning effect - which can only be removed through the natural peeling process of the skin.
