Patients with small breasts are jokingly called the Princess of Peace. Because of their small breasts, multi-level multi-point injections are not possible, and autologous fat injection for breast augmentation was not recommended in the past, but with the accumulation of experience in autologous fat transfer, autologous fat injection for breast augmentation was performed on this group of patients, and it was found that the effect of breast augmentation (breast augmentation) was obvious through the appropriate amount of multiple times of fat.
