Persistent laser outline/pinkness
I had an aggressive CO2 laser treatment done last June for my acne scarring and it has left a faint pink outline on the left side of my face. Sometimes it flares up when I'm stressed/nervous or after doing physical work, but the pinkness settles quickly (within 30 or so seconds). I am concerned that this is permanent damage as I am near one year post-CO2 and I can still see the laser's outline. It has improved over the past couple of months, but extremely slowly. To clarify, I have no pain, inflammation, or change in skin texture in the affected area. The treatment itself helped my acne scars a lot but the pinkness is extremely annoying... and I don't think it should be taking this long to heal from a fractional (albeit aggressive) laser. What can I do to fade it completely?
