Too Much of a Good Thing?

Years ago I read a ton of positive murad reviews and was happy when I found it in nearby stores. The cleansing wash was awesome and took away every zit that popped up within days. Now when I use it it doesn't work as well and I don't know why. My only guess is that my skin got too used to it and it doesn't work as a "medicine" anymore. I still love it though. There's menthol in it and after you rinse your face it's almost like you had a spa treatment. So that's pretty much why I still use it, it's a great relaxation thing and makes me feel like I took time for myself. I wish I could find something that never stops working on my face though. Oh well, we'll just keep searching for that one.
