Science
Mechanism of Action
The synergistic action of Streptococcus Thermophilus and Lactobacillus ferments underpins this ingredient's efficacy. Streptococcus Thermophilus Ferment Filtrate significantly boosts skin hydration, refines texture, and reinforces the skin's protective barrier by stimulating the endogenous production of lipids such as ceramides. As postbiotics, Lactobacillus ferments contribute to superior skin conditioning, anti-aging effects, and skin brightening. They also play a crucial role in balancing the skin microbiome, reducing inflammation, alleviating redness, and regulating skin pH, promoting overall dermal resilience.

Safety
Safety Profile
The CIR Expert Panel has deemed Lactobacillus Ferment ingredients, which include this filtrate, safe for cosmetic applications. These components are primarily fermentation byproducts, not live bacteria. While generally safe and non-toxic, a patch test is recommended for highly sensitive skin due to a minimal potential for allergic reactions. It has demonstrated non-genotoxic, non-irritating (when undiluted), and non-sensitizing properties in assays.
