Recommendation on procedure for flat, long face shape with no definition and long chin? (Photo)

Hello and thank you for your question! Between the fat transfer, canthopexy, and buccal fat removal, I think you are looking for a substantial change to your face. Based on the picture you provided and concerns you mentioned, I think starting with fat grafting to the cheeks/mid-face could provide you with a decent step towards your desired outcomes. If you still are looking for further changes after the fat transfer, then you should look into next steps, however starting with just the fat grafting and going from there could provide you with a good base. As always, it would be best to seek out an in-office consult with a plastic surgeon to best evaluate what procedures and techniques would best work for you and your desired aesthetic goals. Hope this helps!

Thank you for your photo. Yes, fat transfer can improve the proportions of your face and make you look younger. Namely, it can convert a longer face into a more attractive, wider face. I would not remove buccal fat as this will make you look older.
