Exosome therapy (stem-cell supernatant)
Exosome / stem-cell culture supernatant
Exosome and stem-cell supernatant treatments are marketed aggressively by Japanese anti-aging clinics, often to visitors from China, with claims about skin, hair and longevity. None is approved, quality control is up to each clinic, and Japan's regenerative medicine law does not cover these cell-free products. Approach with the same caution as any unproven therapy.
