What should I do if my face is too thin? Facial fat filling is to suction excess fat from the abdomen or thighs, and then transplant it to the required area after treatment. Autologous fat cheek augmentation is a commonly used filler. This method of cheek augmentation attaches great importance to facial recovery and represents the development trend of facial rejuvenation in the future treatment field. Autologous fat cheek augmentation increases the volume and fullness of the face, bringing about a change in the treatment model and making the face younger and more natural.
