Science
Mechanism of Action
This extract exerts its effects by providing robust antioxidant protection against environmental stressors and UV damage. It offers significant soothing action and, being rich in amino acids, it actively strengthens the skin's barrier function and boosts its inherent capacity for moisture retention. The ingredient also contains loliolide, a key compound believed to support cellular longevity and confer visible anti-aging properties, further evidenced by its ability to enhance dermal fibroblast viability.

Stability
The raw material typically presents as a greenish liquid. Fermentation of Scenedesmus deserticola is believed to enhance its beneficial properties. No specific optimal pH range for formulation stability was provided.
Safety
Safety Profile
No specific review status from CIR, SCCS, or FDA was found for Scenedesmus deserticola extract. However, in vitro studies have shown negligible cytotoxicity (less than 10% decrease in cell viability) on normal human dermal fibroblasts for extracts prepared with ethanol, hexane, and ethyl acetate at concentrations of 1 to 20 µg/ml. Studies on related Scenedesmus species extracts also indicated low cytotoxicity on murine lymphocytes at 500 µg/mL and on human PBMCs above 1500 µg/mL. It is noted that distilled water-derived extracts showed higher cytotoxicity.
