Treatments for facial lines after weight loss?

Hi y’all- I’m in my late 20s but am about 50lbs lighter than my college years. I lost a lot of volume in my cheeks specifically and I imagine as a result have this folding around my smile that really bothers me. Any advice on treatments? I currently have a pretty regular skincare routine that prioritizes moisture (dry skin) and incorporates tret (.5%) a few nights a week, recently added Argireline serum, plus regular red light. Considering sculptra as a long term investment specifically but open to ideas!
