About LACTIPLANTIBACILLUS EXTRACELLULAR VESICLES

Extracellular vesicles from Lactiplantibacillus (formerly Lactobacillus) species, probiotic bacteria known for their skin and gut health benefits. These vesicles carry lactic acid, peptides, and fatty acids that can help balance skin, fight acne, and strengthen the skin barrier.

Detailed Analysis

Lactiplantibacillus (reclassified from Lactobacillus plantarum group) is a Gram-positive lactic acid bacterium and well-established probiotic. Its extracellular vesicles (100–300 nm) contain peptidoglycan fragments, lipoteichoic acid, lactic acid, plantaricin peptides, and bacterial RNA. These vesicles can survive gastric transit and penetrate skin follicles. Key skin benefits are mediated through: (1) direct antimicrobial plantaricins targeting acne pathogens; (2) immune modulation via TLR2/NOD1 pathways; (3) barrier strengthening short-chain fatty acids (propionate, acetate). The strain-level variation in vesicle composition is significant for efficacy and safety. Safety profile is strong given extensive probiotic food use history.
