This Vitamin C serum was one of the better I have tried recently, I found it made my skin look pretty good. It lightened some of my hyperpigmentation, especially on my cheeks and forehead. This serum is sold on Amazon.com, like many others I have tried. It comes in a darkened 1 fl. oz./ 30 mL bottle, which is good for the serum, so it does not oxidize.
Buy it here: http://amzn.to/Twkukz It is $29.95.
I received one or more of the products mentioned above for free using Tomoson.com. Regardless, I only recommend products or services I use personally and believe will be good for my readers.
