Exosomes are not stem cells
Cell-derived particles and living cell products require different descriptions and evidence.

A different type of material
Exosomes are a class of small extracellular vesicles released by cells. They are not living stem cells and do not divide into replacement tissue. Products marketed with the exosome label can vary in source and preparation. A description such as stem cell exosomes may refer to the cells used to produce the material, not to living stem cells in the final product.
Why the distinction affects claims
A proposed effect from cell-derived particles involves different mechanisms from permanent cell replacement. Research into signaling does not automatically establish clinical benefit. Ask what the product contains, how it is characterized, and what patient studies support the specific use. A paper about stem cell transplantation is not direct evidence for an exosome injection or topical application.
Route and formulation matter
A product applied to intact skin is different from one injected into tissue or infused into a vein. Safety and effectiveness cannot be assumed to transfer between these routes. The formulation, processing, and intended purpose also matter. A product sold for cosmetic use should not be treated as evidence for a medical procedure merely because the same marketing term appears on the label.
Evaluate the exact offer
Request the product name, manufacturer, source, route, and local authorization basis. Regulatory statements from another country do not settle the status of the Korean service. Ask for human evidence involving the final product rather than general statements about cell communication. Clear terminology helps prevent a promising research concept from being mistaken for a proven treatment.
