After having on and off bouts with a difficult skin infection for years, my Dermatologist, Dr. Robin Fleck of Prescott, Arizona, suggested I try the Original C Serum. This is the first product we found that worked! I now use the product daily. I like the way my skin feels with daily use. I also use the Perfection Creme as a skin soothing after-shave. These are very good products! Thank you!
