Microbiome-Friendly Postbiotic for Barrier Care
Postbiotics are one of the fastest-growing claims in skin care. This Lactobacillus ferment liquid brings that story to toners, barrier creams and masks at one of the lowest prices in our exosome range.
The Source Behind Lactobacillus Ferment Postbiotic Solution (Exosome-Type)
Lactobacillus bacteria are the friendly microbes behind yogurt and kimchi. In cosmetics, their ferments are used to support a balanced-looking skin surface and a comfortable barrier.
Labeling note: The manufacturer markets this material (Lactosome 55) as bacterial exosomes, but its INCI is Lactobacillus Ferment, not Lactobacillus Extracellular Vesicles. We sell it as a postbiotic ferment and call it exosome-type. Do not declare “exosomes” in your INCI list.
Why Formulators Choose Lactobacillus Ferment Postbiotic Solution (Exosome-Type)
Choose it for microbiome-friendly, barrier and sensitive-skin lines. It is honest about what it is: a postbiotic ferment that the manufacturer describes as exosome-rich, labeled under its correct INCI.

FAQ
Is this a live probiotic?
No. It is a ferment (postbiotic); it does not contain live bacteria intended to colonize the skin.
Why is it called exosome-type?
The manufacturer describes it as bacterial exosomes, but the INCI is Lactobacillus Ferment and we have no vesicle data on file, so we do not call it an exosome solution.
What is the recommended use level for Lactobacillus Ferment Postbiotic Solution (Exosome-Type)?
The supplier range is 1–5% in serums, creams, toners and masks. Start at the low end in a test batch and confirm stability in your base.
Does Lactobacillus Ferment Postbiotic Solution (Exosome-Type) contain human-derived material?
No. Every product in our exosome range is plant-, microbial- or marine-derived; we do not sell human-derived exosomes.
How should I store and ship Lactobacillus Ferment Postbiotic Solution (Exosome-Type)?
Store tightly closed in a cool, dark place, away from direct sunlight and heat. Refrigeration is not required: the solution is preserved with a cosmetic preservative suitable for natural and green formulations. Ships by standard shipping; orders ship the next business day. Free standard US shipping on qualifying orders of $49 or more. It ships in 10 mL sample, 1 oz (30 mL) and 4 oz (118 mL).
