Science
Mechanism of Action
The ingredient operates by supplying compounds that bolster skin vitality. Research on its Saussurea involucrata component indicates an ability to elevate immune cytokines, enhance keratin barrier function, diminish melanin production, inhibit collagen-degrading enzymes, and stimulate collagen synthesis. Furthermore, Saussurea involucrata polysaccharides provide antioxidant defense, mitigating UVB-induced oxidative stress and DNA damage, concurrently fostering keratinocyte differentiation and lipid production to combat skin dryness. Metabolites from related Paecilomyces species have also demonstrated tyrosinase inhibitory activity, suggesting a potential role in skin brightening.

Stability
Specific optimal pH ranges and comprehensive stability notes for the combined ferment filtrate are presently unestablished. As a filtrate resulting from fermentation, it is typically anticipated to be water-soluble or readily dispersible in aqueous cosmetic formulations.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Panel has not conducted a specific review for PAECILOMYCES JAPONICA/SAUSSUREA INVOLUCRATA FERMENT EXTRACT FILTRATE. General CIR reports on related 'Yeast-Derived Ingredients' frequently cite an 'Insufficient Data Announcement' (IDA), particularly regarding dermal sensitization. Consequently, definitive safety assessments for this specific ingredient are pending further data.
