Cell-signalling vesicles
Exosomes
INCI: varies (plant, platelet or stem-cell derived exosomes)·Preliminary evidence
Tiny vesicles that carry signalling cargo between cells, the newest headline in prestige serums. The marketing is well ahead of the cosmetic evidence, which is early and mostly brand-led.
Studied for
- ·The appearance of firmness and a rested-looking complexion
- ·The look of a smoother, more even surface
How it’s thought to work
Studied for association with cell-to-cell signalling that may support the appearance of skin renewal; topical delivery and finished-product evidence are still preliminary.
Questions
- Do exosome serums work?
- The idea is interesting, but the cosmetic evidence is preliminary and there is no established topical use level. For now this is a promising area to watch rather than a proven active.
