Anyone? I just ordered some Azelaic acid cream at 20% since I heard it helps with both acne and redness/pigmentation. Has anyone else tried this?

Ok red marks are really consistent, at least on my face. Here is what i do. I rub raw potato twice a day to lighen the spots. You can do it more than twice if you want. For irritated spots i use sudocrem. Its awsome, but any diapper rash cream will do as long as it has high rate of zinc. Dessitin has 40% while sudocrem has12,5%. These creams are miraculous. I also ordered a specifying cream from ebay, but have not tryed it yet. It called contractubex and is for acne scars, keloids or burns. I read it needs many applications daily, but it does work. Check it out on ebay. Geranium essential oil directly applied is also very effective.
