Sure, you should try the 2%!
It is not SUPER strong or scary or anything...I use it every single night. It took only a matter of days
for me to see good results in my skin from using this! You can email Paula's Choice customer service and request free samples of it. It comes in a liquid solution form and a lotion form. The liquid solution takes a while to absorb into your skin, but it doesn't have as much of a chance for clogging your pores as the lotion does. The lotion is also a bit more moisturizing, so if you have oily skin you probably don't need the extra moisture.
I also liked Proactiv.
But, I found that it was too drying and too expensive, and my face is doing even better with Paula's Choice.
So, give the PC 2% a try for at least a couple of weeks or so...then if it doesn't improve, then I'd suggest trying Proaciv! Both companies have a money back guarantee, so it's pretty much safe!
