SVF Facial Fat Grafting
يعرف أيضا باسم: SVF 얼굴성형, SVF 얼굴 지방이식
SVF facial fat grafting is facial fat transfer with the graft enriched by stromal vascular fraction.
What is SVF facial fat grafting?
SVF facial fat grafting is facial fat transfer in which the injected fat is enriched with stromal vascular fraction isolated from part of the harvested fat. The rationale is the same as for cell-assisted grafting elsewhere: added stromal cells may support graft survival. Evidence for the face comes mainly from small series rather than large controlled trials.

نظرة عامة
SVF facial fat grafting, also called cell-assisted lipotransfer, is autologous fat transfer to the face in which the stromal vascular fraction (a cell mix including adipose-derived stromal cells) is isolated from part of the lipoaspirate by collagenase digestion or mechanical processing and added to the injected fat. It is used for facial lipoatrophy, contour deficits and volume restoration, on the rationale that the cells support graft survival. Systematic reviews report higher retention than plain fat grafting, but most studies are small, heterogeneous and of weak quality. The US FDA treats enzymatically processed SVF as more than minimally manipulated, requiring an IND or biologics licence; in Korea, cell-based procedures may fall under the Advanced Regenerative Bio Act. Readers should verify the isolation method, the provider's regulatory status and how retention was measured.
