Fixing dent in butt caused by steroid shot? (Photo)

A small area of fat loss in the buttocks like this could be treated through fat grafting or by utilizing an off-the-shelf product such as Renuva. Fat grafting requires liposuction from somewhere else to collect fat to inject into the area of volume loss, whereas Renuva can be injected much like the fillers we use in the face.

Steroid induced fat atrophy is a fairly uncommon, but potentially devastating complication of steroid injections.
Fat grafting is probably the best long-term option, but it may be difficult to get enough fat to survive in a small area so the procedure may need to be done a couple of times.Fillers are definitely an option, but will be expensive in the long term.
I suggest consulting with plastic surgeons who have a proven track record with fat grafting procedures.
When reviewing before, and after pictures for fat transfer results, always confirm the timeframe of when after pictures were taken. Early fat transfer very impressive but do not necessarily represent final results. After pictures are a more accurate representation 3 to 6 months after surgery.
