What Is Lactobacillus Ferment?
Lactobacillus ferment is a lab-created, non-living probiotic ingredient made by fermentation of the microorganism Lactobacillus. Applied to skin, it’s been shown to have a potent soothing effect that in turn strengthens skin’s ability to defend itself from aggressors. Research has also revealed that this ferment may play a role in helping skin’s microbiome to maintain a healthy mix of flora, a benefit that may reduce the risk or visible severity of several common, often uncomfortable skin conditions.
