Breast augmentation is mainly divided into autologous fat breast augmentation and prosthetic breast augmentation. Prosthetic breast augmentation, as its name implies, is to implant a prosthesis to achieve the purpose of breast augmentation. Usually, silica gel is used. At present, underarm incision is generally used, so as not to leave too obvious scars. Different prices of silica gel materials will have different effects. The other is autologous fat breast augmentation. Usually, the lower body fat is taken, and after treatment, fat cells are injected into the chest to achieve the purpose of breast augmentation, because liposuction can also achieve a certain shaping effect.
