What can be done to minimize the appearance of dents caused by gluteal injections? (photo)

Dear Isis K,
it is hard to tell for sure without an examination. Based on your photo, it looks like you probably have some scar tissue under the dents so you will need subcision to release the tissue and then fat transfer to fill the dent. If you are considering surgery, I would suggest you consult a board-certified plastic surgeon. Only after a thorough examination, you will get more information and recommendations.

Allow me to answer your question as best i can based upon your single photo. However, please keep in mind that an in-person, or at least a virtual, consultation with physical exam is first necessary before any legitimate evaluation or final surgical recommendations can be made.

Because the dents contain scar tissue, BBL fat rarely survives and thus often produces minimal improvement. On the other hand, I have had quite good success utilizing buttock implants to kind of pop-out these dents and create a smoother appearance. Please note that an extremely few number of board certified plastic surgeons specialize in buttock or hip implants, so you may need to travel far and away from home to find this particular surgeon. Glad to help.
