Worried about the safety and side effects of fat grafting
The situation
Before agreeing to any procedure many people want to know what can go wrong. For fat grafting the recorded risks are lumps, oil cysts, calcification, asymmetry, resorption and infection; for cell-enriched grafting the literature adds cyst rates that differ by isolation method. The situation is risk assessment, so the answer lists the complications that studies actually report, how often, and which regulatory body has said what — not reassurance.
Common concerns: fear of complications · distrust of "no side effects" · wanting the worst case spelled out

What regulators have said
- US regulatory status (FDA)
- Fat removed and reimplanted in the same person during the same surgical procedure may qualify for the 21 CFR 1271.15(b) exception if processing is limited to rinsing, cleansing, sizing and shaping (FDA final guidance, November 2017)[2]governmentSame Surgical Procedure Exception under 21 CFR 1271.15(b): Questions and Answers Regarding the Scope of the Exception – Guidance for IndustryU.S. Food and Drug Administration
- Processed adipose cell products (US)
- The FDA considers processing that isolates cellular components from fat, such as enzymatic digestion, to go beyond the same surgical procedure exception[2]governmentSame Surgical Procedure Exception under 21 CFR 1271.15(b): Questions and Answers Regarding the Scope of the Exception – Guidance for IndustryU.S. Food and Drug Administration

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.
