22 yrs old | Post lipo Banana rolls and cellulite not improved after lipo, what now?

An exam would determine what could be done for your physique.  The banana roll is vastly different in different people. To give the absolute best contour, you would need a tiny amount of liposuction performed very carefully to avoid skin laxity below the area of the banana roll to blend the area, a small amount of fat grafting to the current banana roll area. This can be coupled with InMode RFAL skin tightening. 
The procedure combines different clinically proven modalities (radio frequency energy, deep tissue heating and suction coupled negative pressure) to distribute heat to the skin and underlying fat, causing the tissues to contract. Weekly sessions over an eight week period are recommended, but improvement is likely seen after the first few sessions. There are several ways to address cellulite depending upon depth of cellulite, location, elasticity of overall skin envelope, and subcutaneous fat layer.

this is because you had loose skin and didnt have the proper type of treatment, liposuction is not the treatment for this area in a patient with loose skin.  to improve this now there are three options.  From best results to least results1) posteroir thigh lift with scar hidden in buttock crease + internal heating with BodyTite or J plasma + external microneedling RF like Fractora or morpheus82) internal heating with Bodytite or Jplasma + external microneedling RF like Fractora or morpheus83) fillers like sculptra and bellafill or renuva to camoflage the area or fat injections + external microneedling RF like Fractora or morpheus8this needs a full evaluation so you understand that more liposuction will worsen this area and that long term you need both indentation supprot and lifting.  we are constantly fixing this. Best, Dr. Emer.

The big advantage of micro canula liposuction is that you can rough up the underside of the skin to allow contracture which tightens up the sagging skin a lot. There is hope for you.

Thank you for your question and the photos. I think it is best to see a plastic surgeon in person and think about a thigh lift with the scarring nicely in the line below the buttocks ... invisibly to the eye. I think that might give you the best results.Best of luck

Banana rolls can be difficult to remove with just liposuction again. Smaller banana rolls can be treated with conservative liposuction. If the liposuction is too aggressive, it can make the roll larger or increase the number of folds. If you have excess skin which is contributing to the persistent roll, you may need an excisional technique which cuts out the banana roll and hides the scar under your natural buttock crease.
