I tried this and after less than two weeks my husband asked what I was doing differently as my skin was glowing. I've tried other C creams and this is hands down my favorite one. Absolutely love this!

For the cost, I'd say skip it and go straight to the gold stand Skinceuticals CE Ferulic. This one smells better, but if you really want the best, then CE Ferulic is the way to go. There really isn't anything in this that separates it from less expensive Vitamin C serums beyond the higher percentage which really isn't necessary, so either save your money and purchased another serum (Paula's Choices similar, decent, and less costly) or spend the same and get a superior product.

I had some sort of allergic reaction to at least one of the ingredients in this product. I do not have sensitive skin.i have and continue to use many Perricone products,which I generally love. This product however caused me to have 2nd degree burns and swelling over my face..with a concentration of the burns around my eyes and mouth. I've been using only coconut oil on my face for the last 5 days, while it is healing. My face is sort of like one big scab!! This stuff took off at least a layer of my skin. I patch tested it later on my neck, behind my ears and my arms, but had no reaction. I do layer my products and was hoping that maybe this just reacted to one of the other products. However, today, stupidly, mostly because I wanted to love this product, I put a small amount of only this product on my face, in front of my ear over a dark spot. In about an hour,I developed stinging and redness near this area, but it also spread out closer to my under eye, which is not where I put the cream. I am not allergic to most forms of vitamin C or ferulic acid, because I've been using Skin Ceuticals for over a year now...I waited forever to try this product...and bought it last week. I am over 60 and have been using skincare since college. I do not have sensitive skin and have used a zillion products over the years and there's only one other time this happened to me. After comparing ingredients, I see both products contain 3-O-Ethyl Ascorbic Acid, a potent form of vitamin c. I googled this ingredient and found many articles about it causing allergic reactions and dermatitis in users. The most disturbing part of all this is the lack of caring or concern on the part of the customer service rep at Perricone. She basically said to return it! Not impressed with that. I may have to rethink using Perricone at all with that kind of response!
