Lactobacillus is a genus of beneficial probiotic bacteria widely used in cosmetics in the form of ferments or lysates. It is valued for its ability to support the skin’s microbiome, strengthen the skin barrier, and provide natural antimicrobial protection. Rich in lactic acid, peptides, and bioactive metabolites, it helps balance skin pH, soothe irritation, and improve overall skin health. It is commonly used in probiotic skincare, moisturizers, serums, masks, and sensitive skin products as part of the clean beauty and microbiome-friendly trend.
