Lactobacillus/Soymilk Ferment Filtrate

This ingredient is a filtrate from soymilk that has been fermented with Lactobacillus. The word "filtrate" means you're getting fermentation by-products, not live probiotic bacteria.

It is a gentle skin conditioning ingredient used to help skin feel softer, calmer, and more hydrated. In cosmetic research, "probiotic/postbiotic" style ingredients are commonly discussed in the context of supporting the skin's micro-ecology and barrier function.

Just be cautious if you're allergic to soy, and be sure to patch test even though it's processed/filtered.
