A comprehensive office evaluation will clarify your options and alternatives. The surgeon will discuss the differences between excess fat vs skin and how to treat the condition through non invasive methods or perhaps surgery.
Make sure you have a thorough consultation with a board certified plastic surgeon who has extensive experience in this procedure. Check her/his experience, credentials, reviews, before and after photos, and have a quality consultation.
It is preferred for your surgeon to be member of "American Society of Plastic Surgeons" and ideally member of "American Society for Aesthetic Plastic Surgery". This means they have been evaluated by the society and recognized that the focus of their practice is high volume and quality, honest aesthetic plastic surgery and they adhere to a code of ethics.
