I tried the Murad system for about a week, and I am reacting terribly. My face is actually swollen. I am taking Benadryl and Ibuprofen to calm it down. It is almost like I got a bad sunburn. There are tiny fluid filled blisters all over my face. I was sooooo hopeful that this would be the last product that I would ever have to buy. Just be careful and don't try the product if you have a major or important event coming up, in case you have this reaction.
