I also use the 2% liquid solution.
I don't use any of her cleansers because I've had great luck with Purpose Moisturizing Foaming cleanser, and I don't want to try switching, just in case I break out. If it ain't broke, don't fix it, right?
I also don't use any of her toners, moisturizers, or BPO products because my skin simply doesn't need them. It's fine with my gentle cleanser, the BHAs, and nothing else. http://www.healthboards.com/ubb/gabby.gif
