Lactobacillus Ferment Lysate
Lactobacillus Ferment · Lactobacillus Ferment LysateSoothing
A fermented-bacteria ingredient sold as “microbiome support”. One maker-run study with no placebo found less redness.
What it does
It’s what’s left after fermenting Lactobacillus bacteria: broken-down cells and what they made. A 30-day study by the company that makes one version tested a lotion with four Lactobacillus lysates. Users lost less water through the skin, looked less red and had more moisture, but there was no placebo lotion to compare. Whether it changes skin’s bacteria is unknown.
