Science
Mechanism of Action
This complex ingredient operates through a synergistic blend of components. The Saccharomyces Ferment Filtrate supplies vital nutrients, antioxidants, and amino acids, which collectively reduce inflammation, stimulate collagen synthesis, and refine skin elasticity and texture. It actively strengthens the skin's natural barrier, boosts moisture retention, and may contribute to skin brightening by moderating melanin production. This component also supports the skin's defense against water loss and UV damage by regulating keratinocyte proliferation and activating the aryl Hydrocarbon receptor (AhR), while its anti-inflammatory properties are beneficial for managing acne and calming irritation. The Hop extract component adds potent antioxidant, anti-inflammatory, and antimicrobial actions, specifically targeting acne-causing bacteria like P. acnes and S. aureus. It also aids in softening keratin, facilitating the removal of keratotic plugs to improve pore appearance, and functions as a sunscreening agent, offering protection from erythema while potentially promoting tanning.

The Formula
Formulation
Stability
Optimal pH for healthy yeast fermentation, a core process for this ingredient, is within the 5.2-5.5 range. Hop oils necessitate emulsification for uniform dispersion in formulations. Liquid malt extracts may undergo darkening over time, even under proper storage. It is recommended to store the Saccharomyces Ferment component in a cool, dry place, shielded from direct sunlight.
Safety
Safety Profile
The CIR has deemed yeast-derived ingredients, including Saccharomyces Ferment Filtrate, safe for cosmetic use under current practices, assuming appropriate sourcing. Saccharomyces cerevisiae holds GRAS (Generally Recognized As Safe) status from the FDA for food use up to 5%. Hop extracts are considered non-toxic and non-irritating when applied topically.
