I stumbled upon using vitamin C for acne quite by accident. A while back I was taking vitamin C supplements for a cold which was due to an allergy. While the cold stayed put, I noticed that my acne was healing faster and my skin was looking better. The skin tone was even and my skin looked clearer. I had not been doing anything else different, so I was pretty certain it was the vitamin C. Pretty intrigued, I took to the internet to do some research.
