I've been using Mad Hippie Skin Care Products for a while now and this is one of my favorites. Changes in the seasons, living on the east coast, and working outside does a number on my skin. The Vitamin C serum definitely works. I noticed a difference in the first few weeks of using this product. I used to buy this at the Whole Foods near my house, but on www.iherb.com the price is lower. I would give it six out of five stars if I could. Mad Hippie Never Disappoints!!!!
