What Is Resveratrol Glycoside? — A Thorough Comparison with Conventional Resveratrol
Challenges of Resveratrol
Trans-resveratrol is a polyphenol found in grape skins and wine, known for its powerful antioxidant properties. However, there were significant challenges when using it as a cosmetic ingredient.
- — Light instability :Rapidly degrades and isomerizes to cis-form when exposed to UV light
- — Low water solubility :Nearly insoluble in water, making product formulation difficult
- — Oxidation susceptibility :Easily oxidizes in air, reducing effectiveness
Solution Through Glycosylation
SIRT Lab's patented technology performs "glycosylation" by binding sugar molecules to trans-resveratrol. This chemical modification provides:
1. Dramatically improved light stability — Maintains stable structure even under UV exposure
2. Significantly improved water solubility — Easy to formulate into water-based products
3. Sustained release — Sugar molecules gradually detach on the skin, continuously releasing active resveratrol
Advantages as a Cosmetic Ingredient
Glycosylated resveratrol can be incorporated into a wide range of formulations including creams, serums, and lotions. Its high stability significantly extends product shelf life compared to conventional alternatives.
