Science
Mechanism of Action
This ferment filtrate operates through several key pathways. It acts as a robust antioxidant by directly inhibiting oxidation and significantly reducing UV-B induced reactive oxygen species (ROS). It bolsters the skin's natural defense by increasing total glutathione (GSH) and superoxide dismutase (SOD) activity. For anti-aging and anti-photoaging effects, it enhances collagen production while concurrently decreasing levels of matrix metalloproteinases (MMP-1, proMMP-2, and proMMP-9), enzymes responsible for collagen degradation. Furthermore, it exhibits anti-inflammatory properties, contributes to skin barrier protection, and demonstrates antimelanogenic activity through tyrosinase suppression, thereby reducing melanin synthesis. Astringent and hair conditioning properties are also noted.

Safety Profile
The CIR Expert Panel deemed 'Lactobacillus Ferment ingredients,' including Lactobacillus Ferment Filtrate, safe for cosmetic use. No genotoxicity was observed in Ames assays with related ferment ingredients. While tyrosinase inhibition may suggest a skin lightening effect, formulators are advised to ensure use does not lead to unwanted depigmentation. The specified maximum concentration of 5.6% applies to the broader category of 'Lactobacillus Ferment' in face, neck, and other skin care preparations.
