It is a procedure performed to fill facial irregularities and clefts, including sunken cheeks, the disappearance of fat from the cheekbones, deep grooves that run from the nose to the corners of the mouth, and in some cases, also the lines between the lower eyelid and the cheek. It is also one of the most common methods used for lip augmentation. The fat is usually extracted from the abdomen or inner thigh. The aspirated fat is processed by centrifugation, filtration or washing. This fat is rich in stem cells, which helps us to obtain a smoother skin in addition to the filling effect.
