Science
Mechanism of Action
This complex operates through the combined actions of its constituents. The Saccharomyces Ferment Filtrate component delivers vital nutrients and antioxidants, reduces inflammation, and stimulates the skin's natural collagen production. It fortifies the skin barrier, provides moisture, and supports a healthy skin microbiome, potentially reducing hyperpigmentation, acne, and sebum. Hydrolyzed Collagen functions as a humectant, attracting and retaining skin moisture. Its constituent peptides serve as crucial building blocks for collagen and elastin, simultaneously signaling fibroblasts to synthesize new collagen, elastin, and hyaluronic acid. While sucrose acts as a humectant, its fermented form within this filtrate augments the overall skin-conditioning and beneficial properties inherent to fermented ingredients.
Research
Clinical Evidence
Medium confidence0.1%
Key findings
- 01 Saccharomyces Ferment Filtrate, a key component, is recommended at 0.1%-5% in leave-on products, demonstrating improvements in overall skin health, nutrient and antioxidant supply, inflammation reduction, collagen promotion, and enhanced elasticity and texture, alongside reduced fine lines and wrinkles. It also strengthens the skin barrier and moisturizes.
- 02 Topical application of a dried Saccharomyces Cerevisiae ferment resulted in a decrease in histamine-induced skin inflammation in a human clinical study.
- 03 In vitro studies (0.3-10 μg/mL) of fermented black ginseng using Saccharomyces cerevisiae (FBG) showed a significant increase in type I procollagen expression in human fibroblasts, with clinical studies on FBG in cosmetic formulations reporting anti-wrinkle and skin whitening effects.
Transparency
Dusting Analysis
Data regarding common 'dusting' practices for this specific complex is not available. Efficacy depends on adequate concentration of the active components, with individual Saccharomyces Ferment Filtrate showing efficacy from 0.1% in leave-on products.
The Formula
Formulation
Stability
The hydrolyzed collagen component maintains stability within a pH range of 3.68 to 5.70. For optimal skin compatibility and product stability, the final formulation's pH should align with the skin's physiological range of 4.5-6.5.
Synergies
- The combination of fermented filtrate and hydrolyzed collagen provides comprehensive benefits for skin hydration, collagen synthesis, and barrier support.
- Hydrolyzed collagen can form films when combined with other biopolymers, enhancing its conditioning properties.
Conflicts
- Hydrolyzed collagen alone lacks film-forming capabilities and requires co-formulation with other biopolymers for this effect.
Safety
Safety Profile
The comprehensive 'SACCHAROMYCES/HYDROLYZED COLLAGEN/SUCROSE FERMENT FILTRATE' has not undergone individual safety assessment by CIR or SCCS. However, its individual components are generally considered safe: Saccharomyces Ferment Filtrate is regarded as safe with no reported side effects (patch test recommended for general yeast ferments), and Hydrolyzed Collagen is a recognized safe cosmetic ingredient. The FDA classifies Saccharomyces cerevisiae as 'generally recognized as safe (GRAS)' for specific food uses. The CIR Expert Panel is currently reviewing yeast-derived ingredients, with broader requests for dermal sensitization data.
