Erythrulose

Description

Erythrulose is a naturally occurring keto-sugar that has gained popularity in the skincare industry as an alternative to traditional self-tanning agents. This compound is derived from red berries and belongs to the family of dihydroxyacetones (DHAs). Unlike its more commonly known counterpart, DHA, erythrulose reacts more slowly with amino acids in the skin's surface, resulting in a gradual, longer-lasting tan.

The molecular structure of erythrulose allows it to penetrate the stratum corneum, where it interacts with keratin proteins to produce a color change through the Maillard reaction. This process typically takes 24-48 hours to develop fully. Erythrulose offers several advantages over traditional tanning agents, including a more natural-looking color, reduced likelihood of streaking, and improved fade characteristics.

In formulations, erythrulose is often combined with DHA to enhance overall performance and color development. It is considered less irritating than DHA alone, making it suitable for sensitive skin types. Erythrulose is typically used in concentrations ranging from 1-5% in self-tanning products. While generally well-tolerated, some individuals may experience mild skin irritation or allergic reactions, necessitating patch testing before widespread use.
