# SVF Facial Fat Grafting

SVF facial fat grafting is facial fat transfer with the graft enriched by stromal vascular fraction.

## Key facts

- **Definition**: Cell-assisted lipotransfer: SVF is isolated from half of the harvested fat and recombined with the remaining fat before injection [1]
- **First facial clinical report**: 2008, Yoshimura et al. (University of Tokyo), Dermatologic Surgery 34(9); facial lipoatrophy, 3 CAL vs 3 conventional patients [1]
- **Pooled retention difference (all sites)**: SVF-enriched grafts: +17.20 percentage points in mean retention vs conventional (95% CI 11.26–23.15); 18 studies, 893 patients; authors call for more standardized RCTs [1]
- **Reported safety**: No serious adverse events attributed to SVF enrichment in the included studies (follow-up up to 4 years); minor bruising and swelling; nonrandomized studies at serious risk of bias [2]
- **SVF isolation methods**: Enzymatic (collagenase) or mechanical; mechanical isolation gives lower total cell yield but comparable viability [3]
- **US regulatory position**: FDA stated that processing adipose tissue into SVF is more than minimal manipulation, that the same-surgical-procedure exception does not apply, and that a BLA or IND is required [4]
- **Applicable FDA guidance**: Regulatory Considerations for HCT/Ps: Minimal Manipulation and Homologous Use (docket FDA-2017-D-6146) [5]
- **Korean institution designation**: MOHW designates advanced regenerative medicine institutions (첨단재생의료실시기관) for high-risk cell therapy; MFDS separately licenses cell-processing facilities [6]

## Overview

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.
