Fat augmentation is theoretically long-lasting, but fat volume reduction can occur with age. Therefore, the maintenance time of fat breast augmentation is related to the individual body type and the presence or absence of significant wasting, and usually, the maintenance effect time is about 20-30 years. Autologous fat breast augmentation is a better method of breast augmentation because the fat comes from the body and there is no need to worry about its rejection reaction. Although about 30% of the fat is discharged out of the body with the circulation and cannot survive, once the remaining 70% of the fat survives, the amount of fat will not become less like the fat in other parts of the body, so theoretically it can be maintained for life. Patients are advised to massage their breasts regularly every day to promote blood circulation in the breasts and slow down fat aging; pay attention to regular work and rest and avoid spicy and stimulating foods. It is recommended that patients who have the desire for autologous fat breast augmentation can visit the plastic surgery department of local tertiary hospitals for an interview, and if they have the indications, i.e. sagging breasts or small breasts, they can adopt this surgical method to give themselves satisfactory breasts.
