I have been using this product for over 3 years and all I can say is watch out! This product is ADDICTIVE. I have become an addict to the soft radiant skin that is revealed only when I use this product. Since I started using P50, I get compliments on my skin so frequently that I wish I could just carry around samples of the stuff to give away. The only problem is when I run out of this stuff. I recently ran out and realized that my twice yearly expeditions (the large bottle lasts six months for me; a little really does go a long way) to Philadelphia from DC to purchase this stuff is absurd so I'm now surfing looking for this product online. Caveat emptor girls. Make sure you keep this stuff well stocked or you and your skin will go through a very sad withdrawal.
