What is the most effective way to get rid of banana rolls on an 18 year old? (Photo)

Meems,In my opinion, coolsculpting (cold applicator) or kybella (injections) are your best options.  Both are non-surgical with little to no downtime.  Both require a series of treatments. Good luck!

Non-invasive technologies aren't fantastic for your issue here, but they do have less downsides, aside from cost.  On the other hand, you are young and with good skin.  Careful liposuction has a good chance of helping, but you have to be choosy in who you select to do the procedure.  In the wrong hands, if you get a posterior thigh crease or other problem, that can be difficult to fix.  But in the right hands liposuction in this area can work out reasonably well for you.

Based on my 20 year experience of helping women with exact problem that you have, I have found that skilled and experienced micro liposuction is the gold standard treatment for this.  It is most cost effective and least problematic if all treatments that you could encounter searching online. 

There are many options however over liposuction in this area can cause worsening. I suggest you see an expert to see if you are a candidate for non invasive options like kybella or internal heating.  Best, Dr. Emer.

Hello Meems, if you haven't already decided yet where to go, consider doing Ultraslim as a nonsurgical alternative and also as an alternative to Coolsculpting.  Although Coolsculpting is nonsurgical, like liposuction, it kills fat cells, put undue strain on your body.  Also fat cells can come back in different areas, causing the body to look lumpy and uneven.
With Ultraslim, the fat cells are naturally excreted from the body, not killed.  The treatment also helps collagen and elastin and is truly an effective contouring treatment.  See our before and after pictures to see how.  Ultraslim is also less costly than Coolscuplting and Lipo.  Indeed you may have to return over and over again with Coolscupting and Lipo to correct problems and that will be incredibly costly.

I would suggest a very mild amount of carefully performed Liposuction in this area. I agree that Cool Sculpting will afford zero to mild Results after you spend thousands of dollars to have it done. Conversely, the Liposuction removes the fat and gives the best most predictable body contouring results.
