Query: Disappointing

The first few days, I was sure this was a great product. It actually felt good on my skin, I didn't even need to use a moisturizer afterward, which I always do. But after a few weeks, my skin wasn't looking any better, and it was getting really dry. I started applying once a day instead of twice, but it didn't matter, my skin kept getting dry and I kept getting pimples. After five weeks, I had to discontinue use. I'm not sure why it worked so well for the other people here, maybe it was just my skin.
