If I have InjectIons Can I Put Fat on my Butt?

The key concept is that fat transfer relies on the newly moved fat cells establishing a reliable blood supply. Any foreign body or scar tissue decreases a plastic surgeons ability to safely and effectively use fat to enhance your contour. Even previous fat transfer makes this process more difficult. In addition - be aware there are no "substances" or products that are approved for enhancing the size or shape of your buttocks. Things like silicone injections for this purpose can create significant problems in the future. We exclusively use fat transfer for this purpose because it has a safe, reliable track record.

Clinical Context

Different injectable materials behave differently in tissue. Some fillers break down naturally over time, while others, like silicone, become permanently incorporated into surrounding tissue and cannot be reversed or removed. This matters for fat transfer because your surgeon needs to work with healthy, unobstructed tissue to establish blood supply to the transferred fat. Being upfront with your surgeon about any past injections—what was used, when, and where—helps them plan safely and set realistic expectations for your results.
