I have jowls and volume loss in my cheeks. What can I do to reverse this? (Photo)

Thank you for posting your question here!My answer will be based on the limited information and pictures provided, for a detailed and personalized plan please consult with a plastic surgeon in person.
based on the provided picture , I would probably take a multifaceted approach starting with performing buccal fat removal as it appears that you have some herniated buccal fat. I would also likely recommend a facelift and depending on which form of facelift is done your surgeon might also consider a midfacelift.you still appear to have the volume in your cheeks they just appear to have drooped and you likely just need to reposition the malar fat pad with a midfacelift. A profile picture is lacking though and that would help with deciding if you really need volume through either fat grafting or cheek implants.I hope this helps, Best of luck!
