Review (1/5): WARNING - Caused me to breakout in large welts all over my face and neck. Due to a technical glitch, the reviews are misleading!
This review is for "#1 Pure Vitamin C Serum - Doctor Recommended" by Natures Design. FOR SOME REASON THE REVIEWS FOR THIS PRODUCT ARE COMBINED WITH THE REVIEWS FOR "CeraVe Foaming Facial Cleanser, 12 Ounce", SO READ THE REVIEWS CAREFULLY! Unfortunately for me, I did not catch this until after I purchased and used the Nature's Design product. Amazon has been notified of this technical glitch. Maybe they will have fixed it by the time you read this. At the time I purchased the Natures's Design product, there were nearly 800 reviews attributed to it, with a 4.5 star rating. Again, because of the reviews being combined with those for the CeraVe product, there is no way to discern the true rating for the Nature's Design product unless you read all 800 reviews.
The reason for my negative review is that is caused me to breakout in large welts all over my neck and face, and cost me a trip to the Dermatologist and resulting medication to deal with it. I even did a 24-hour skin test on the inside of my forearm prior to applying it to my face, and followed the directions for use. According to my Dermatologist, "People aren't allergic to Vitamin C or Hyaluronic Acid, they're allergic to the preservatives that are added to products." For what it's worth, I have never had any allergic reaction to any other product prior to this, and don't have overly-sensitive skin.
I contacted Amazon customer service and they are refunding the cost of the product. However that does not reimburse me for time, pain, Dr's. visit, and medication to deal with it.
Good luck if you decide to try this anyway. I hope it works for you.
