Mechanism of Function
Reactive Oxygen Species Scavenging
L-Ergothioneine functions as a cellular antioxidant agent, helping to neutralize free radicals that may contribute to oxidative stress on skin.
Skin Defense Support
As a naturally derived sulfur-containing amino acid, EGT is recognized by skin cells and may assist the skin's natural defense mechanisms against environmental stressors.
Metal Ion Chelation
EGT exhibits metal-chelating properties that help moderate transition metal ions in cosmetic formulations, contributing to product stability.
Formulation Stability
With good thermal stability and pH tolerance, EGT integrates smoothly into various cosmetic delivery systems and helps maintain product shelf life.
Formulation Applications
Anti-Oxidant Serums & Ampoules
- Formulated as a functional active ingredient in concentrated serums and ampoules targeting oxidative stress-related skin concerns.
- Suitable for water-based delivery systems requiring high solubility and stability.
- Compatible with common cosmetic preservatives and thickeners in serum formulations.
Daily Skincare Products
- Incorporated into creams, lotions, and essences as a daily-use protective ingredient supporting overall skin wellness.
- Ideal for daytime and nighttime moisturizers seeking enhanced antioxidant protection.
- Functions well in emulsion-based systems with a wide pH tolerance range.
Functional Sun Care & After-Sun Products
- Used in sun protection formulations for its complementary role in addressing UV-induced oxidative damage.
- After-sun care products benefit from EGT's soothing and protective properties.
- Stable under exposure to light and moderate heat, suitable for outdoor-use formulations.
