Science
Mechanism of Action
The Pichia Ferment Extract Filtrate operates primarily as a humectant and skin conditioning agent, effectively attracting and retaining moisture within the skin while forming a proactive barrier to prevent water loss. Rich in essential amino acids and peptides, it stimulates epidermal cell turnover, supporting skin regeneration and leading to improvements in texture and overall appearance. Furthermore, it offers potent antioxidant properties, shielding the skin from free radical damage and oxidative stress. This ingredient also provides soothing benefits, helping to calm irritation and reduce redness. The underlying fermentation process involving Pichia pastoris is linked to the upregulation of cellular activity.

Stability
During its production, specifically the fermentation process involving Pichia pastoris, pH is typically maintained in an acidic to slightly acidic range of 5.0 to 6.0 using ammonium hydroxide. The optimal pH range for stability within a finished cosmetic formulation has not been explicitly stated in available data.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) is currently conducting a safety assessment of yeast-derived ingredients, which encompasses Pichia Ferment Extract Filtrate. While identified as a skin protectant and conditioning agent, a final 'safe as used' determination with specific maximum concentrations is not yet available. However, Pichia pastoris, the microorganism from which this ferment extract is derived, has a robust history of safe industrial use since the 1980s, recognized as non-pathogenic and non-toxigenic.
