I have these melasma areas under my eyes and above the lip. They became visible after 6 Sylfirm X procedures I had for acne scars that ended Nov 2022. I have some remaining acne scars in one cheek. Will Co2 help or is Pico or other laser better? I also had taken progesterone treatment. The melasma is not well defined in shape, it is diffused. I am wearing spf 50+ for years now, all year long, and reapply correctly. Also I have some small hiperpigmented spots from acne on my cheeks.
