Science
Mechanism of Action
This ingredient functions as a humectant, forming a protective barrier to deeply moisturize the skin. It stimulates collagen production, thereby reducing the appearance of fine lines and wrinkles while boosting skin elasticity. It refines skin texture by minimizing pore visibility, brightens the complexion by addressing uneven skin tone and hyperpigmentation, and provides anti-inflammatory and soothing effects for sensitive or irritated skin. Additionally, it enhances the absorption of other active ingredients, aids in skin detoxification, and acts as a prebiotic to support a balanced skin microbiome, fostering beneficial bacteria and strengthening skin defenses.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has issued an 'Insufficient Data Announcement' for a group of yeast-derived ingredients, including Saccharomyces Ferment, specifically requesting confirmatory dermal sensitization data and information on the food use/Generally Recognized As Safe (GRAS) status of the parent yeast species. While Saccharomyces cerevisiae, the progenitor yeast, is recognized as GRAS by the FDA for certain food applications up to 5%, specific review data for Saccharomyces/Magnesium Ferment from SCCS was not found.
