How can I fix my sagging cheeks / nasolabial folds? Will jaw surgery or cheek lift help? (Photo)

I've tried: threads (so painful and made me look weird), cheek and NLF filler (didn't make a big difference), and am currently being suggested a double jaw surgery ( I have an overbite) to bring my maxilla 3-4 mm forward and mandible 10 mm forward, or just the lower jaw. I am in my late 20s, and have a BMI of 18.5. I am just not sure that such a small maxilla movement will lift my cheeks. I've always had a very round face.
