If you don't know about Paula's Choice, you are missing out. Her story began when she took it upon herself to analyze and "grade" as many professional skin products as she possibly could and publish a book "Don't Go the the Cosmetics Counter Without Me!" I got it from my sister for a holiday gift. Paula was strict-she outlawed anything that came in a "jar", told you when a product was poorly packaged (like if it allowed sunlight to get through and destroy ingredients) and gave only those products that were both incredibly effective and accurately priced (not overpriced) her high ratings. I went through my products and threw half of them away. At some point, Paula threw up her hands and developed her own line, Paula's Choice. There are some incredible, affordable, amazing products in this line. The acne kit resurfaced my skin to the point that I get compliments and asked "what do you use" every week of my life. This particular product is one of the TOP of all tops. It had a packaging issue that has now been resolved. I love the way it feels on my face, and I feel a true, remarkable difference using it. I put it on my arm where I had scarring and it helped that too! I also love her BHA 2% gel. Like a salicylic toner that you don't swipe on, you glide on and it stays there, to kill any impending pimples. So many amazing products, this one being a personal favorite, you'll find yourself trying more than one, and it won't break the bank! Thanks Paula!
