I'have acne scar on my cheek and it really bothers me, even though some people say it is not that visible. I believe it is ice pick (it has some dents), but not really sure. I use vitamin a cream for at least one year and I've done a course of 4 sessions of microneedling + PRP, but I didint notice results. Would CO2 laser be a good option to treat it? Im 36 years old, by the way.
