Silicone implants remain the same volume unless there are post-operative complications. However, after fat grafting, it is necessary to wait 6 months to a year. This is because a certain amount of the transferred fat may be reabsorbed, and this varies from person to person. Therefore, the final shape can only be determined after one year. Following fat grafting, the amount of reabsorption will largely be apparent within the first month, depending on the patient's smoking habits and activity level. If a second procedure is deemed necessary, a year should be waited to assess the final result.

In buttock augmentation with silicone implants, swelling subsides after a few months, and the final result is permanent. However, aging may cause some changes, but the volume of the silicone implant will remain unchanged.
