Acne scars ㅠㅠ

Now that I'm in my 30s, I don't get acne as often as I used to, but I'm more stressed about the scars left on my chin....

Even with makeup, the pitted marks aren't covered well, and they stand out even more under lighting, so it really bothers me. I thought it would get better over time, but since there hasn't been as much change as I expected, I am currently looking into laser treatments. Procedures like Fraxel, PicoFraxel, and Subcision are highly recommended; for those who have actually received them, which treatment were you most satisfied with? I am also curious whether the effects are noticeable after a single session or if multiple sessions are necessary, as well as the pain level and recovery period. Since costs seem to vary significantly by clinic, I am having trouble making a decision. If anyone has struggled with acne scars on their chin and achieved satisfactory results, I would really appreciate it if you could share tips on choosing a clinic and how to manage the aftercare!
