Hi Clint88
I think the website recommended a gel texture for oily/combination skin and a lotion for normal/dry skin.
So being an idiot I ordered the lotion by mistake 
I can't remember why it suggested 2% instead of 1% but any 2% is what I've got.
The first difference was that the oil on my T-zone disappeared. I hadn't really thought I had oily skin until it vanished and I realised how bad it had been!
The second difference was that all the spots across my forehead dried up and I stopped making new ones.
A couple of deep spots that had been around for ages not coming to a head slowly started to disappear.
And then the blackheads on my nose all disappeared and that's it!
A couple of spots suddenly came out as I settled into the new regime but now I don't have any at all. I'm using Cetaphil as a cleanser (Paula's recommendation that cleanser is the least important step so I didn't buy hers
), could happily go without moisturiser but am using a SPF moisturiser in the day.
All the changes and drying up happened in under a fortnight. If I'd known it was this easy I'd have done it YEARS ago - I've bought loads of face scrubby things and clay masky things over the years as I thought that was how you exfoliated, how wrong could I be? Best exfoliation ever with a gentle cleanser and a lotion.
