my dermatologist told me to stop using moisturizer, as he believes it contributes to my acne. he also gave me an oral antibiotic for my acne and two topicals (one for AM one for PM). my skin has become so dry and though i've quit using the topicals for about two or three days now, my face still feels like sandpaper. should i use a moisturizer, like jojoba oil, or should i listen to my dermatologist?
