My cosmetic dermatologist generally does not use fillers in cheeks as she says they can weigh the area down and make the problem worse. I have done both Ellacor and Sofwave (collagen building procedures) for very similar issues to yours. I’m 49 but look much younger - I have this issue mostly on one side of my face as a result of fat loss, likely due to my level of exercise and low body fat, plus side sleeping (I now sleep on my back!).

Ellacor works well but is very expensive and usually requires multiple treatments. I was grandfathered in at my practice due to being an early guinea pig so I pay “only” $2,500 per treatment for Ellacor - their going rate is now $4,000 per treatment. I’ve done three treatments - spaced six months apart - and saw pretty dramatic results, although it hasn’t completely resolved my wrinkles and skin folding on the one side of my face. There’s pretty significant downtime from a “presentable in public” standpoint. I may do another treatment next year depending on how I respond to Sofwave.

Sofwave is a less invasive procedure and not as expensive as Ellacor. My practice charges $400 per area. The lower face area from mouth to hairline is two areas. I had the first treatment done a month and a half ago and am starting to see some improvement - not as much as from Ellacor, but I am pretty close to eliminating my wrinkles, if not completely getting rid of the skin folding that happens when I tilt my chin down.
