I use Dermalogica and love it. I use the normal-oily skin range and I find you don't have to use very much at all to get results. My beautician put me onto this as since I've had Emily, I've been getting breakouts often.
I use the cleanser, toner, moisturiser & mask.
I've never used Proactive, so can't compare on the 2. But Dermalogica has been very gentle on my skin.
