For your skin
The exosome-facial active from Korean clinics. The strongest evidence is as a booster paired with microneedling or laser (where it improved wrinkles and tone), rather than as a stand-alone leave-on. Promising but still early; treat it as a clinic-adjacent extra, not a proven daily essential.

Nanoscale vesicles secreted by mesenchymal stem cells that carry growth factors, peptides, and signaling RNA, which prompt fibroblasts to increase collagen and modulate repair. Distinct from plant-derived exosomes.
