"sophomore year of college, literally over a couple weeks, i developed severe acne all over my cheeks. i went to the dermatologist and they gave me differin. i definitely would wake up and need to put lotion on my face because my face was visibly dry and had dead skin coming off. after about a month, i started seeing results and had less pimples on my face. after about 6 months my face was clear, but i still had acne scars. i had treatments done at the dermatologist to help those. it&#039;s been 5 years and now i get complemented for my skin all the time. it&#039;s great! still using differin every other week and cetaphil face lotion every day."
