About LACTOBACILLUS

Lactic-acid bacteria used in probiotic-inspired skincare. Generally gentle and microbiome-friendly, but real live-culture formulas are preservation-challenging.

Detailed Analysis

Lactobacillus, on a cosmetic ingredient label, refers to inactivated cells, fragments, or ferment fractions of lactic-acid bacteria (L. rhamnosus, L. plantarum, etc.). The genus has GRAS status in food and a strong pharmaceutical safety record. In skincare it is used for microbiome-support claims, soothing, and skin conditioning. True live cultures are rare in cosmetics because stability and preservation are demanding — most marketed "Lactobacillus" products are lysates or ferments rather than living organisms. No EU restriction.
