Science
Mechanism of Action
This ferment extract filtrate operates through a multifaceted mechanism, leveraging the bioactivity of both its Saccharomyces and Rubus Arcticus components. The Saccharomyces ferment delivers vital nutrients and potent antioxidants that mitigate inflammation, stimulate collagen synthesis, and boost skin elasticity, leading to a visibly refined skin texture and a reduction in the appearance of fine lines. It also fortifies the skin's natural barrier, provides hydration, and helps regulate sebum production. Crucially, it may stimulate cellular oxygen uptake and the production of soluble elastin by human fibroblasts, supplying human-like cytokines and growth factors such as TGFb, IL-1a, and EGF, which are essential for healthy skin regeneration. Concurrently, the Rubus Arcticus Callus Extract contributes antimicrobial, antioxidant, humectant, and protective conditioning actions.

Stability
While specific stability data for this exact combined ingredient is limited, related yeast lysates exhibit general stability for approximately 1 year under normal storage conditions. It is best incorporated into the aqueous phase of a formulation, ideally in the final steps if heat is applied during processing, to prevent degradation. A pH range of 3.5-6.5 has been observed for the stability of some related ferment lysates.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed 'Saccharomyces Ferment Extract Lysate Filtrate' and related yeast ferments as safe for use in cosmetics, provided the yeast species have adequate dermal sensitization data and a recognized safe status (e.g., GRAS, QPS). While no universal maximum concentration is specified for this exact combined ingredient, related Saccharomyces Ferment Filtrate is typically recommended at 0.1%-5% in leave-on products and up to 10% in rinse-off formulations. Saccharomyces Lysate Extract has been used up to 0.067% in baby products and 0.1-2.8% (with 1% often recommended) in anti-aging applications. FDA does not typically approve cosmetic ingredients directly, regulating them under the Federal Food, Drug, and Cosmetic Act.
