Lactobacillus/​Hydrolyzed Collagen Ferment Filtrate Extract

What is it?

Lactobacillus/Hydrolyzed Collagen Ferment Filtrate Extract is a bio-fermented ingredient obtained by fermenting hydrolyzed collagen with Lactobacillus.
After fermentation, the mixture is filtered to remove microbial cells, leaving a clear filtrate rich in bioavailable peptides, amino acids, and fermentation-derived metabolites.

The fermentation process enhances the skin affinity and absorption of collagen-derived components while introducing skin-conditioning and soothing benefits from Lactobacillus metabolites.
