I had an awful looking blemish under my eye and a friend gave me Zinc C Serum and told me it was a miracle worker. This blemish was a really ugly one that was right under the eye so it was making my under eye look puffy as well. I used the Zinc C Serum and in just two days the blemish is completely gone! I have dealt with acne for twenty-five years and tried everything under the sun. This was the BEST solution so far!
