Live Lactobacillus Cultures
What is it?
Live Lactobacillus cultures are probiotic bacterial strains used topically to support the skin microbiome, with immunomodulatory, anti-inflammatory and antimicrobial properties.
What does it do?
Commonly used to help rebalance the skin microbiome and calm inflammation. A GRADE systematic review and meta-analysis of randomized controlled trials found Lactobacillus-based microbiome therapy effective for acne vulgaris with a favorable safety profile, and a separate randomized double-blind trial found Lactobacillus-derived postbiotics improved a chronic inflammatory skin condition.
