acne
"I experienced most of the side effects that my dermatologist told me about, primarily the dry skin portion. I was instructed to avoid chlorine, avoid direct sun light w/o sunscreen, and other things. The dry skin was really the only really not fun part, it was almost like eczema. I had large patches on my arms, and primarily at the corners of my mouth that were extremely painful when cracked. The doctor did recommend some facial moisturizers (Cerave), cleansers(Cerave), and lip balm(Aquaphor) to help in the healing process, which I still use today :)  I was extremely pleased with my results and occasionally had zits after the use but nothing compared to the initial skin. My skin also recovered great!"
