I've struggled with moderate acne since ~grade 7, and I'm 18 now. I haven't picked at it since middle school, but I have these awful red marks that just won't go away! From researching, I think they're hyperpigmentation? My dermatologist doesn't seem to think they're a big deal, and gave me a 5% glycolic acid moisturizer thing that doesn't help at all. I'm wondering if I should look into chemical peels/other removal methods, but my skin is so sensitive that I'm not sure if it would worsen.
