Best options for permanent results on cheek scar
I would say the best option you have for permanent improvement of the scar on your left cheek would be a scar revision. This should not cause more damage to surrounding hair follicles. In essence, you would be trading scars for one that is less noticeable than the one you have now. In the ideal situation, you would be left with a flat, thin scar instead of the round, depressed scar that you have.
Indented scar on the cheek
I would recommend a combination of Ematrix RF, fillers, Erbium laser, and fractional lasers to help smooth out your cheek scar.
