It's really the only product that works for me, though even this stuff does not compleatly help.
2-3 times a week does not work for me, every other day didn't even work that well. I have to use it everyday. Though I've had the same amount of dryness from the 2 times a week as I have from the everyday.
Though I've not making the product sound that great, I still gave it a 4/5, as it's the best thing I've used so far, and I can't be without it.
Also, people on here complain about the smell, I never thought it was so bad. Kind of nice really.
By the way, get it off ebay or Amazon, you can get it MUCH cheaper, and you don't have to deal with the HORRIBLE Proactiv website. Seriously, stay away from there.
