Skin conditioning Hair conditioning Hydration Barrier Support Antioxidant Anti-inflammatory Collagen Production Microbiome Support Odor Reduction

Science

Mechanism of Action

This fermented complex utilizes Saccharomyces cerevisiae to complex essential sea silt minerals and microelements with low molecular weight proteins, facilitating their efficient transport into skin cells. It promotes significant improvement in skin hydration, partly by activating aquaporin 3 expression, critical channels for water transport. Beyond hydration, it strengthens the skin's natural barrier, offers antioxidant defense against environmental stressors, and assists in reducing inflammation while promoting collagen production. As a prebiotic, it nurtures beneficial skin microbes, supporting a healthy microbiome, and contributes to natural odor reduction through enzymatic bio-conversion of malodorous substances.

Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel has issued an 'Insufficient Data Announcement' for the broader category of yeast-derived ingredients, requesting additional confirmatory dermal sensitization data and information on GRAS (Generally Recognized As Safe) status. While the Environmental Working Group (EWG) rates Saccharomyces/Sea Silt Ferment with 'LOW' concern for cancer, allergies, and developmental toxicity (with 'LIMITED-FAIR' data), and related ingredients like Saccharomyces Ferment Filtrate are considered safe, further comprehensive data is needed. Maximum recommended use levels for related Saccharomyces ferments are up to 5% in leave-on products and up to 10% in rinse-off products, with a 10% concentration having been studied in an in vivo hydration setting.
