Worrying that the transplanted fat will not survive
The situation
Fat grafting has a known weakness: part of every graft is resorbed. People in this situation want to know what fraction usually survives, what raises or lowers survival, whether cell enrichment changes it, how many sessions may be needed, and how to interpret a clinic's quoted survival rate. The neutral answer separates pooled figures from single-clinic figures and notes how each was measured.
Common concerns: fear of wasted money · fear of repeat surgery · scepticism of quoted rates

How to verify an institution
Instead of a ranking, use the public records that exist for this kind of procedure in Korea.
- Check the Ministry of Health and Welfare list of designated advanced regenerative medicine institutions for the designation number.
- Check the cell-processing facility permit register (K-ARM) when cells are isolated or processed.
- Treat case counts, success rates and "first" claims published by the institution itself as official claims until an independent record confirms them.
Providers in this domain that an independent regulator, registry or peer-reviewed venue names, listed alphabetically. Being listed is a record, not a recommendation.
