Exosomes are cell-derived vesicles containing signalling molecules that have been investigated for potential regenerative effects. While research is ongoing, they are not licensed for injection treatments in humans in Spain. Their discussion here is for informational purposes only.

Exosomes may have applications in topical skincare or as part of laboratory research, but any injectable use should only be conducted within approved clinical studies or experimental settings.

Patients should be cautious of providers offering exosome injections outside regulated medical frameworks. Safety, sterility, and professional oversight are essential whenever regenerative therapies are considered.
