When I was in middle and high school, I had very severe acne, and the scars were very severe. At that time, I tried MTS and there was no way, so I did Fraxel... 11 years ago, Fraxel said that it hurts more than having a baby, so I did it under sleep anesthesia . Since then, I don't know if any lasers hurt. However, I have tried all kinds of lasers since then because of these scar pores, but none have worked as well as the Fraxel I got 11 years ago. Except for a few scars on the butterfly zone and pores, the scars on the cheeks and temples were almost resolved with this powerful Fraxel. Originally, I had to use it 3 times to see the effect, but it was very painful, and the redness seems to have gone for almost a year. At that time, I regretted doing it for nothing for a year, but when I look back, I wonder what I would have done if I hadn't done that powerful one. I've been taking Fraxel lately, and it doesn't hurt that much, but the effect seems to be negligible. If I go back to that time, I want to do it again with sedation.
