LACTOBACILLUS/COLLAGEN FERMENT EXTRACT.

Valuable / SKIN CONDITIONING

Lactobacillus/Collagen Ferment Extract is a bio-fermented complex designed to enhance skin hydration and support barrier function. It integrates the benefits of probiotic ferments with collagen fragments, aiming to improve skin elasticity, reduce lines, and calm redness.

Science

Mechanism of Action

This extract functions as a humectant and skin conditioning agent, drawing and retaining moisture within cosmetic formulations. The polycollagen peptides present are theorized to mimic natural collagen fragments, thereby supporting the skin's intrinsic repair processes and contributing to a reduction in the appearance of lines and wrinkles. The Lactobacillus fermentation process optimizes the bioavailability of beneficial compounds, which are known to fortify the skin barrier through ceramide production, balance the skin's natural microbiome, mitigate inflammation, and offer anti-microbial and hydrating effects. Additionally, it may contribute to reducing hyperpigmentation by inhibiting tyrosinase and offer protective benefits against environmental stressors by acting as a DNA repair enzyme.
