I'm curious about reviews of acne scar treatments!

I have a rather large acne scar on my cheek. Lately, I have been seriously considering acne scar treatment, and I am asking this question because I think reviews from people who have actually received the procedures would be very helpful! I’ve heard that there are various types of acne scar treatments, such as Fraxel, lasers, and chemical peels, but looking at the reviews for each, the effectiveness and satisfaction levels seem to vary quite a bit. I suppose it’s inevitable that it varies from person to person. In particular, according to acne scar treatment reviews, I am worried because pain, recovery time, and the degree of skin irritation seem to differ from person to person. My skin is extremely sensitive and thin. I am curious whether I need multiple treatments to see results, and how long the side effects, redness, and hyperpigmentation mentioned in reviews last. Are there any people among those who have actually undergone acne scar treatment who have very sensitive skin? I would appreciate it if you could share your experiences and recommend any procedures or things I should avoid!
