Gluteal indentations are either cost by connective tissue, pulling on the skin in a condition called cellulite, or when there’s a history of previous procedures or trauma it is usually scar tissue pulling on the skin.

The tissue that’s pulling on the skin needs to be released by some type of Subsicion procedure. adding some volume with grafting fat at the same time often gives the best results and the best long-term outcome. Simply adding volume, especially on this part of the body is a simplistic way of thinking of the problem, which does not recognize what causes contour irregularities on the buttocks. You can think of cellulite or contour irregularities due to contractile tissue forces like tufted furniture. If you have a tufted sofa with texture created with buttons sewn in Creating a purposeful pattern stuffing the sofa further is going to make the indentations where the tufts are look even more accentuated.

Treating contour, irregularities and cellulite is not easy and lots of people have had disappointing outcomes from plastic surgeons, trying various treatments for years. It would be helpful if providers would learn from the past and not take the simplistic approach of simply just adding volume.

Look for providers who have a proven track record treating cellulite with long-term success with enough before, and after pictures to confirm their track record. Best, Mats Hagstrom, MD
