Hi, I'm in Europe for a while where it's legal to buy real glycolic acid in pharmacies. I'm hoping someone with experience on the subject of facial peels will answer my question. I'd like to do a glycolic peel at home. Since I can buy products between 3% and 70% glycolic acid ~ what should I start with?? I have small, faint discolorations all over my face from years of acne (no raised or indented scars though). Also, if I try to apply it evenly, there shouldn't be much risk with peeling certain areas deeper than others right? Yes, I have read quite a bit on the subject and am aware there will be stinging & redness for a full evening afterwards. Thank you for any sound advice!!
