Query: The most work I've done for the smallest effect.

This product was really unimpressive. It helped my skin, but not nearly the effect that I had gotten when I tried Proactiv. I wish I wasn't banking on it making me pristine before my wedding. Mostly my problem is oily skin, so it might be different for someone with different skin. The bottle sizes are very different, so it was easy to run out of one bottle before the other.
