Best treatment for banana rolls? I am 5'4", 115 lbs. (photos)

Hello dear!
Thanks for the pictures and provided information as well.
Based on your photos, you are a good candidate for a small amount of liposuction and fat transfer, to fix your problem and improve your buttocks, and I think you'll get very good results.
l recommend you to make an in-person consultation with a board certified plastic surgeon for a proper answer and to talk about your goals and anything you need to know.
Good luck :)
 

It is very difficult to determine the exact size and shape implant you will require to best match your ideal butt image without an examination by a board certified plastic surgeon. Not just any board certified plastic surgeon, but one with many years of frequently performing breast augmentation surgery including different approaches, techniques and implant choices. This is because several measurements not to mention your breast characteristics are needed to determine the optimal implant size to obtain your goals. Without knowing these dimensions it would be difficult to make this determination. For example, the existing base width of your buttock will determine, in many cases, the maximal volume per implant profile that you can accommodate. Liposuction of your lower back and fat transfer is also helpful as an adjunct to implants. Using “want to be” photos however are useful if simply provided to the surgeon.

This can be lip suctioned but it can be risky and depends on your skin elasticity.   I would rather you try a non invasive treatment first.  Look into Vasershape ultrasound technology. I have found that it really helps to melt away small amounts of unwanted fat without the risk of surgery.
