Based on the photo it looks like a portion of the problem is excess fat. You look fairly young so the first thing I’d recommend is a consult with a qualified surgeon. From there I’d discuss options but highly recommend considering a fitness or diet program to achieve some weight loss before considering any other action.
Once your weight goals have been met then we could discuss possible lipo treatments to further sculpt the appearance you desire. If there is any action required beyond that, it can be discussed during a follow-up consult. The important thing is to discuss all your options with your doctor and don’t rush into any unnecessary surgery.
