I got laser treatment for a scar ~

I had a fingernail scar from when I was 13, about 2 cm on my nose. When I was young, it was not very noticeable, but as I got older, maybe because my skin elasticity decreased, it gradually became more noticeable. About 10 years ago, when I was in college, I went to a dermatology clinic, and they often sent me away saying there was no real solution for an old fingernail scar. At one clinic, they did Fraxel laser treatment for me. I think it was about 100,000 won per session. In the end, it did not improve at all. So now that I am thirty, I took a photo and the scar stood out much more than usual, so I went to a dermatology clinic thinking, this is my last try!! I searched for a specialist and went there. After looking at it, they said it could improve enough, and they did scar sculpting for me. It was not just blindly blasting Fraxel laser right away, but first gently shaving down and smoothing the scar with a laser, then applying the Fraxel laser,,?? That was the principle. I am not an expert, so the terms or explanation may be slightly different, but that was the idea. Anyway, I am only on my second session now, but the depth already seems to have become much shallower, and I guess I should say the bumpy scar has become smoother,, I should have done it earlier Why am I only doing it now I think it would have been better if I had done it when my healing ability was better, haha. I am expecting about 8 sessions, and it will get a lot better, right? Haha I am excited ~ A face without flaws even when taking photos haha Everyone, I think scar treatment should be done by a specialist!!
