Exosomes

Exosomes are nanoscale extracellular vesicles released by cells and used for intercellular communication. They can carry proteins, lipids and nucleic acids, which has created substantial interest in regenerative and aesthetic dermatology.

Early human studies and systematic reviews report promising short-term results for skin rejuvenation, often when exosome preparations are combined with microneedling, lasers or other procedures. However, source material, isolation methods, dosing and product characterization are not standardized, and ordinary cosmetic products marketed as 'exosome' skincare should not be assumed equivalent to studied clinical preparations.
