The process of hip enlargement usually takes 3-5 hours. The methods of hip augmentation include hip augmentation with prosthesis and hip augmentation with autologous fat injection. The method of hip augmentation with prosthesis requires surgery, so it has great damage to tissue and long recovery time. Autologous fat injection is to implant autologous fat into the buttocks by injection, which is less traumatic and easier to recover after operation. It will return to normal in about 2~5 months.
