Dents in both sides of the butt, look like panty lines? 31yrs, 5'7/152lbs. (Photos)

Liposuction in the flank areas above the dents to remove the excess fat could be helpful. If needed, fat could also be transferred to the dents. Enodomologie treatments with radiofrequency can be helpful for cellulite.

this is volume loss and sagging, you wil need fillers + trusculpt FLEx. fat grafting if you have enough.

Sculptra with the right dilution doesn't cause nodules in the buttock and is very safe.  It should be  combined with RF treatments to get the sculptra to work even better/stimulate it to produce collagen such as venus legacy / exilis ultra / thermage / inmode forma or contoura.  We often will add bellafill or renuva to certain areas to improve indentations or the buttock roll to get more definition and softening or to improve overall size and shape.  Smooth novathreads do very well to improve laxity of the buttock as well non surgically.  Just know that sculptra takes numerous treatments and vials, its a large expense and must be maintained at least 2 times a year after a series of treatments for the best result.  Dr. Emer.

Deep buttock creases and flatness can be improved with fat grafting; cellulite will not. Initial improvement may be noticed due to swelling but this is not of a long duration. Reliable remedies for cellulite treatment are still to be found.
