L-Erythrulose is a natural-based keto-sugar that reacts with the amino acids in the keratin protein on the outer or dead surface layer of the skin (the stratum corneum layer of the epidermis).

 

This nontoxic reaction produces a temporary browning effect similar to the Maillard reaction. This is not a stain or dye, but rather a chemical reaction that produces a colour change on all treated skin. The reaction is similar to the browning effect seen when a cut apple slice is exposed to oxygen.

 

The brown colour is comparable to the appearance of a UV-based suntan. Because the skin continually exfoliates itself, losing thousands of dead surface skin cells each day, the tan hue is temporary. The tan appearance lasts from two to 10 days, depending on application type and skin condition.

L-Erythrulose is a clear to pale-yellowish liquid, which naturally occurs in red Raspberries, and is manufactured from the aerobic fermentation of the bacterium Gluconobacter, followed by extensive multi-step purification.

L-Erythrulose and Dihydroxyacetone (DHA) are very similar in composition, and both react much the same way on the skin surface. L-Erythrulose produces a lighter and slower-developing tan, taking

24 to 48 hours to complete development. When used alone, it fades faster than a DHA-based sunless tan. Some people feel the final tone of L-Erythrulose is slightly redder, and less bronze, than the DHA-based tan. It may be less drying to the skin surface, helping provide a smoother fading tint.

When combined with DHA, the resulting sunless tan is said to last longer, fade better, and provide more cosmetically pleasing colour tone.

Main Functions:

※ Synergistic self-tanning effect when used together with DHA

※  Provides a natural, deep and even tan whereas DHA alone may create an orange tone and stripes

※  Erythrulose may prolong the tan and leaves the skin less dry
