Hello, thanks for your question and photos. Unfortunately I don't have any information about you age now, how many years ago your surgery was performed, your life style ( diet, smoking, exercise etc.) and you medical; history (e.g.). My approach always involves a detailed medical history and assessment of the face and the neck as a whole unit in order identify the area required treatment and achieve balance and proportion among the different areas of face/neck. There are several skin-tightening methods (surgical and non- surgical) to approach the fat and skin under chin. In my opinion there is a possibility in your case to Vaser liposuction ( NOT only Lipo) in combination with Renuvion on neck/jawline area or Facetite//Necktite in combination with Morpheus 8 ( 3 sessions). The combination of the 2 technologies can give a better possibility to reduce the fat on the chin area, improve your Jaw line definition and skin tightening. I would like to wait 3 to 6 months after the procedure and consider some filler on the Cheek, Jaw line and chin if required to improve more balance. The procedure can be performed awake with local anaesthesia. I have experience in both Renuvion and facetite/necktite. 1) Renuvion requires only 1 session. 2) Bodytite requires 1 session in combination with Morpheus 8 (3 sessions 4 to 6 weeks apart). Morpheus 8 involves microneedling and Radiofrequency and could be quite discomfort at high level of energy for better results. For this reason, in my clinic , Morpheus 8 is performed by a surgeon with experience in local anesthetic infiltration to reduce the discomfort. The aftercare is very important including manual lymphatic drainage and a garment support for few days to maintain and improve results. I would recommend to make an appointment with a surgeon expert in face/neck for a medical/surgical assessment in order to make a bespoke treatment. Best Wishes, Dr Giuseppe Fiore
