Science
Mechanism of Action
Through a carefully controlled fermentation process, this ingredient provides a bioavailable blend of components, including cordycepin, polysaccharides, and adenosine, primarily from Cordyceps militaris. These compounds are believed to be potent antioxidants, actively neutralizing oxidative stress and supporting optimal skin cellular function. It further contributes to skin health by stimulating collagen synthesis and preserving elasticity, while its anti-inflammatory properties work to reduce visible redness, irritation, and sensitivity. The ferment also aids in strengthening the skin barrier and facilitating cell renewal, with some Lactobacillus ferments additionally exhibiting an ability to inhibit tyrosinase activity, which can contribute to a more uniform skin tone.

Key findings
- 01 Cordycepin, a specific compound within Cordyceps militaris, demonstrably reduced reactive oxygen species (ROS) levels by 55% in in-vitro fibroblast models over 24 hours, highlighting significant antioxidant potential.
- 02 A related ingredient, Lactobacillus Ferment Lysate Filtrate, showed a 47% reduction in skin redness in an in-vivo study with 5 participants, suggesting potent soothing and anti-irritant properties.
- 03 In in-vitro assessments, Cordyceps militaris extracts exhibited inhibitory activity against bacteria known to cause skin diseases.

Stability
This ferment filtrate is understood to be stable and active in acidic environments, consistent with the lactic acid production by Lactobacillus species during fermentation. The optimal initial pH for Cordyceps militaris fermentation is noted as 6.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that 'Lactobacillus Ferment Ingredients' (a broader category including similar ferments) are safe for use in cosmetics. A maximum concentration of 1.5% for Lactobacillus Ferment has been reported in makeup bases. While the Panel noted that some Lactobacillus Ferment ingredients may inhibit tyrosinase activity, potentially leading to a skin lightening effect (which could be considered a drug effect), these concerns were mitigated by the ingredient's known mechanism and extensive clinical experience. Formulators are advised to ensure usage does not result in unintended skin depigmentation.
