Apr 5 2011 Most of us know Proactiv from infomercials touting its three-step skin care system. But did you know there's an entire Proactiv product line? Yep. It's just extremely hard to find, but you can order by phone (888-819-2019) if you're so inclined. One item in particular is worth tracking down. I recently had a facial that used Proactiv's Pore Refining Peel ($20), and my complexion looked practically poreless afterward. It's due to the formula's glycolic acid, which exfoliates all the dead, dull skin. Whether you have acne or not, glycolic acid is one of those ingredients that — when used judiciously — gives skin that glowy, fresh look. You'll feel mild stinging when applying the peel, but the results are well worth it. And at $20 for 15 treatments, your wallet won't feel too much of a sting, either.
