What do you recommend to correct uneven lipo on stomach without general anaesthesia? Looks worse in person.

3 years ago I had a BBL with lipo on my belly. I thought going to a popular doctor with a higher price would guarantee best results but now I don't even feel comfortable in a 2 piece swimsuit or showing midriff and the doctor was not receptive to my concerns. I am 31 with no children but feel like my stomach looks like someone much older who birthed many kids. Would appreciate recommendations for non invasive procedures that are cost effective since the original procedure took so much money.
