acne
"My acne became worst within the first 2 weeks of using Differin, then all of a sudden it began to get better.  The improvements must have happened at night because I would get excited in the mornings when I washed my face.  I have to strongly agree with the person who posted before me.  DO NOT GET YOUR EYEBROWS WAXED while using this product. My skin was ripped off and immediately turned red. A day or so later it left this large UGLY scar under my eyebrows. About a week later it peeled and was fine, but who wants to go through that."
