FAEX.

Valuable CAS 68876-77-7 / SKIN CONDITIONING

FAEX, a natural yeast extract derived from Saccharomyces cerevisiae, is a complex ingredient rich in beneficial metabolites. It is known to support skin health by enhancing the skin's natural barrier, providing substantial hydration, and offering antioxidant defense against environmental aggressors.

Summary

skin conditioning skin protecting soothing antioxidant moisturizing film-forming

Science

Mechanism of Action

FAEX delivers a diverse array of yeast metabolites, including essential sugars, vitamins, amino acids, and flavonoids, directly to the skin. Its composition, particularly beta-glucan, contributes to a soothing effect and acts as a mild antioxidant, deactivating harmful free radicals that can lead to moisture loss. By helping the skin retain water, FAEX improves moisturization and forms a protective film, thereby strengthening the skin barrier and making it more resilient. It may also function as a gentle biosurfactant for cleansing and delivers vital nutrients to stimulate skin cells.

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) is actively assessing yeast-derived ingredients, including FAEX, with a draft report grouping 56 such ingredients considered in June 2023. However, a definitive 'safe as used' conclusion or specific maximum concentration for FAEX itself is not yet available. While the FDA does not require pre-market approval for cosmetic ingredients (excluding color additives), and companies are responsible for safety, the European Union's SCCS, which evaluates cosmetic ingredient safety, has not provided specific safety assessments or maximum concentrations for FAEX in the provided data.

Verdict

Valuable

FAEX is a valuable multi-functional ingredient for strengthening the skin barrier, moisturizing, and providing antioxidant benefits, though further specific safety data regarding its maximum concentration and potential for irritation/comedogenicity would solidify its profile.
