Science
Mechanism of Action
This ingredient, derived from fermented and lysed yeast cells, delivers a rich cocktail of amino acids, peptides, beta-glucans, vitamins, and minerals. It significantly boosts oxygen uptake in skin cells by up to 750% and accelerates cell turnover activity by up to 25%, thereby enhancing metabolic function and supporting lipid balance. It promotes collagen and elastin synthesis, markedly increases hyaluronic acid production, functions as a humectant, and helps normalize the skin's microbiome. Additionally, it offers potent antioxidant properties, aids in sebum balance, inhibits tyrosinase activity to reduce dullness, and supplies natural moisturizing factors (NMFs).

Dusting Analysis
Clinical efficacy for Saccharomyces Lysate Extract Filtrate is observed across a broad range from 0.1% to 20%. However, the Expert Panel for Cosmetic Ingredient Safety (CIR) deemed a related ingredient, Saccharomyces Lysate Extract, safe up to 0.067% in baby products. This substantial disparity between clinically effective concentrations for the 'Filtrate' and the maximum concentration cited for a 'related Extract' suggests potential for dusting. Brands utilizing higher concentrations for their clinically observed benefits must ensure the specific 'Filtrate' ingredient meets stringent CIR safety conditions, including specific yeast species derivation, robust dermal sensitization data, and GRAS/QPS status, as the 0.067% guideline highlights a conservative benchmark for related materials.
The Formula
Formulation
Stability
As a non-living postbiotic, lysate, and ferment filtrate, it exhibits excellent stability, functioning effectively within standard formulation pH ranges, optimally between pH 5 and 6. For prolonged integrity, storage in a cool, dark, and dry environment is recommended.

Safety
Safety Profile
The CIR concluded that Saccharomyces Lysate Extract Filtrate is safe under specific conditions: when derived from particular yeast species with adequate dermal sensitization data and a food use/GRAS/QPS (Qualified Presumption of Safety) status. It's noted that a related ingredient, Saccharomyces Lysate Extract, is used up to 0.067% in baby products, which serves as a guiding maximum for sensitive applications. Adherence to these derivation and data requirements is crucial for ensuring safety, especially when incorporating concentrations beyond this noted maximum.
