Dimples on buttocks. What are they and how can I fix them? (Photo)

It appears to me, based on this photo, that more extensive surgery which would include liposuction of waist and shaping-augmentation of buttocks, may be more appropriate than trying to fix the dents. Fat grafting may improve dents to a certain degree but will not eliminate them entirely. In person consultation with a board certified plastic surgeon is recommended. Good luck.

Dear Considerate470238,
it is hard to tell for sure without an examination. Based on your photos, it looks like you would benefit from fat transfer to buttocks. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

You also have un shaped buttock along with denting/dimpling. I recommend multiple sessions. 1st is surgery of lipo 360/BBL to correct shape and denting. After 3-6 months injections of QWO to improve dimples/cellulite, in 3 sessions under local anesthesia.
