Condition
Facial Rejuvenation
Focused on fat-graft retention and skin quality.
Quick summary
- • Cell-assisted lipotransfer is a common research term
Overview
This research area is closer to plastic surgery than internal medicine.
Mechanisms studied
Survival of grafted adipose tissue is studied.
Human research
Small RCTs compare with fat grafting alone.
Safety
Reported adverse events are mostly local — swelling, pain, or bruising at the harvest and injection sites. Infection and cell-processing quality remain the key risks to monitor.
Evidence limitations
Existing studies are limited by sample size, methodology, and follow-up, and SVF preparation differs substantially between centres, making cross-study comparison difficult.
