Erythrulose is a distinctive four-carbon ketone sugar known for its application in cosmetic products, particularly in sunless tanning solutions. As a clear, yellow, and highly viscous liquid, it is produced through biotechnological processes. When blended with dihydroxyacetone (DHA), Erythrulose enhances the tanning effect, yielding a longer-lasting, more natural-looking tan with a desirable sun-bronzed appearance, while also mitigating the dryness often associated with DHA-based formulations. Moreover, Erythrulose can independently induce gradual, streak-free skin pigmentation, extend the duration of a natural tan, and provide a moisturizing effect, making it a favored ingredient for achieving a healthy-looking complexion.
What is Erythrulose and how is it produced?
Erythrulose is a unique four-carbon ketone sugar, known scientifically as a ketotetrose. It is produced through biotechnological processes. In its aqueous form, it appears as a clear, yellow, and highly viscous liquid.
How does Erythrulose benefit users when combined with DHA in sunless tanning products?
When Erythrulose is combined with DHA (dihydroxyacetone) in sunless tanning products, it enhances the tanning effect by providing a longer-lasting and more natural-looking tan. This combination helps achieve an attractive sun-bronzed color while reducing the dryness that is commonly associated with DHA-based products.
Can Erythrulose be used without DHA, and what are its effects?
Yes, Erythrulose can be used without DHA. On its own, it induces progressive skin pigmentation that is streak-free, prolongs the appearance of a natural tan, and leaves the skin less dry compared to products containing only DHA.
What are the cosmetic benefits of Erythrulose for the skin?
Erythrulose is widely used in cosmetics to promote "healthy-looking" skin. It contributes to a natural tan appearance without the harsh drying effects often linked with traditional tanning products, enhancing the overall aesthetics and hydration of the skin.
