This is me right now. I have been using azelaic acid for 3 days. And retin a micro .04% at night for about 2-3 weeks, I do not know the exact amount of time. The lighting is very good so you cannot see any red marks, unless you examine really closely. I have quite a lot of milia and red marks on my forehead but here you may see like 1 mark. It's all good.
