Exosomes are nanoscale vesicles (30–150 nm) secreted by cells under specific conditions. With an intact membrane and rich in growth factors, signaling proteins, and regulatory molecules, they serve as key mediators for precise cellular communication and regenerative signaling.
Exosomes are DNA-free and non-replicative, offering enhanced safety for applications in skin anti-aging, tissue repair, and hair follicle rejuvenation.
