"I rated this product a 4 instead of a 5 for the simple reason that it could be too harsh for some skin types. I felt some mild stinging upon my first application which is a contraindication noted on the package. This soon faded and with repeated use, it hasn't occured again. For my extremely dry skin, it's an excellent product. I ordered it for the first time just recently, but it's definitely one I will order again and again."
