Inquiry regarding acne treatment effectiveness and side effects

Hello. I am writing to inquire about the red marks and bumpy scars left behind, even though I am no longer getting acne.

Every time I look in the mirror, my skin tone looks dull and doesn't cover it well even with makeup, so I am looking into laser treatments.

What is the most cost-effective procedure for my condition?

I've heard that you usually need at least 5 scar laser treatments to see results, so I'm curious if it really makes the skin dramatically smooth.

Please share your experience regarding whether your skin became thinner or more sensitive, and how you managed post-procedure care.
