About LACTOBACILLUS EXTRACELLULAR VESICLES

Extracellular vesicles (nanoscale lipid capsules) from Lactobacillus bacteria. Novel postbiotic ingredient — preliminary safety looks OK but regulation is catching up.

Detailed Analysis

Lactobacillus extracellular vesicles are bacterial-origin nanovesicles (membrane vesicles, ≈30-300 nm) isolated from Lactobacillus culture supernatants. They are promoted as postbiotic skin actives for microbiome support, soothing and barrier repair. Unlike mammalian exosomes, bacterial-origin vesicles do not trigger human-tissue prohibitions; however, exosome/vesicle cosmetics as a class are under active regulatory scrutiny (EU and US FDA). No CIR or SCCS opinions exist; no standardised quality metrics; composition varies. Bacterial components (LPS analogues, cell-wall fragments) could theoretically drive immune reactions.
