Science
Mechanism of Action
This ingredient operates by synergizing the individual benefits of its two primary components. The Saccharomyces ferment filtrate delivers essential nutrients and powerful antioxidants, contributing to reduced inflammation, stimulation of collagen synthesis, and improvements in skin elasticity and texture, thereby minimizing the visibility of fine lines and wrinkles. Concurrently, Cordyceps sinensis is rich in bioactive compounds including nucleosides, polysaccharides, and proteins, which provide anti-inflammatory, antioxidant, and immunomodulatory actions. Specifically, Cordyceps extracts have demonstrated antityrosinase activity for skin brightening, anticollagenase and antielastase properties for enhanced firmness and elasticity, and photoprotective effects that support UV defense.
Research
Clinical Evidence
Medium confidenceWhile specific optimal percentages for the combined ferment filtrate are not precisely defined, related Saccharomyces Ferment Filtrate is typically recommended for leave-on cosmetic applications within a range of 0.1% to 5%.
Key findings
- 01 Saccharomyces Ferment Filtrate, a related ingredient, has been shown to improve overall skin health and appearance, reduce inflammation, promote collagen production, enhance skin elasticity, refine skin texture, and diminish the appearance of fine lines and wrinkles.
- 02 Ethyl acetate mycelial extracts of Ophiocordyceps sinensis (Cordyceps sinensis) strains exhibited potent antityrosinase and antielastase activities in in vitro assays, alongside moderate anticollagenase activity. These extracts also demonstrated significant photoprotective effects, reaching a sun protection factor (SPF) of up to 25.

Formulation
Stability
Fermentation processes for Cordyceps sinensis generally occur within a pH range of 6.0-8.0, with optimal mycelial growth often observed between pH 7.0-7.5. Although these parameters guide production, specific stability data for the final SACCHAROMYCES/CORDYCEPS SINENSIS FERMENT FILTRATE within complex cosmetic formulations are not extensively detailed. As with many ferment-derived ingredients, robust preservative systems are critical to maintain the integrity and shelf-life of the finished product.
Safety
Safety Profile
A formal safety assessment by regulatory bodies such as CIR, SCCS, or FDA specifically for 'SACCHAROMYCES/CORDYCEPS SINENSIS FERMENT FILTRATE' is not currently available, and Paula's Choice indicates it is 'Not rated.' However, the more generalized 'Saccharomyces Ferment Filtrate' is widely regarded as a safe cosmetic ingredient with no reported side effects, recommended for use at 0.1%-5% in leave-on and up to 10% in rinse-off products. The CIR has reviewed other Yeast-Derived Ingredients, including Saccharomyces Ferment Filtrate, noting their use in cosmetics.
