Science
Mechanism of Action
This ingredient functions as a potent antioxidant, actively protecting skin cells from the damaging effects of oxidative stress and free radicals. It demonstrably enhances skin hydration, improves elasticity, and reinforces the skin's natural barrier function. Furthermore, it exhibits anti-aging properties by reducing the appearance of fine lines and wrinkles, contributes to a more even skin tone by brightening the complexion and diminishing age spots, and possesses anti-inflammatory capabilities to potentially alleviate redness and irritation.

Stability
For optimal stability, store this ingredient within a temperature range of 23-25°C, though it tolerates 16-32°C. It must be kept in a dry environment and not subjected to freezing. It is crucial to note that while Saccharomyces cerevisiae thrives in pH 4.0-6.0, ferrous iron ions are susceptible to oxidation into ferric ions and subsequent precipitation in aerobic conditions when the pH exceeds 5.0.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not conducted a specific standalone safety assessment for Saccharomyces/Iron Ferment. However, its foundational component, Saccharomyces cerevisiae yeast, is generally recognized as safe (GRAS) by the FDA for food applications at concentrations not exceeding 5%. No dedicated safety assessments by CIR or SCCS for the specific ferment have been identified. EWG indicates that it is designated safe for general or limited food use by the FDA and is not suspected to be an environmental toxin.
