Improving Facial Fat Graft Survival Using Stromal Vascular Fraction–Enriched Lipotransfer: A Multicenter Randomized Controlled Study

Although previous clinical studies have reported that cell-assisted lipotransfer increases the fat survival rate in facial fat transplants, most were case studies without quantitative evaluation. A multicenter randomized controlled study was performed to evaluate the safety and efficacy of the stromal vascular fraction (SVF) in facial fat grafts.
