Autologous fat transfer for nasolabial folds involves extracting fat from areas with abundant fat reserves (e.g., abdomen, buttocks, thighs) via liposuction. The fat is then purified into pure fat particles and injected into the nasolabial folds to fill and eliminate wrinkles. While it carries no risk of rejection, certain limitations exist.
Disadvantages of autologous fat transfer for nasolabial folds:
1. Higher cost. The procedure typically ranges from 12,000 to 50,000 yuan.
2. Low survival rate of transplanted fat particles.
