I have an old childhood scar. I have done much RF microneedling and Pico laser sover the years, and it has improved my overall skin texture but has not done much for my scar. I just want my scar texture to improve, I know it will never go away. A surgeon recommended a scar revision surgery, but I don’t want to go that route given the unpredictability of what the new scar will look like. Thanks!
