I was using this for about 1.5 months (every other day) with no problem, and I was seeing results. Then, one night I woke up in the middle of the night and my face was badly stinging and itching; when I looked in the mirror I saw my face was blotchy red. Since I hadn't had any issues, I chalked it up to the extremely dry and cold air that was generally causing my skin to dry out. So I scaled back using this to 2x/week, but was still having a reaction. I stopped using it entirely for a few weeks. Recently, the weather/air has started improving, so I gave it another shot. Once again, I woke up in the middle of the night wanting to claw the skin off of my face. Very disappointed, since I was seeing results in the beginning.
