For your face i would recommend a cleanser and moisturiser by Lutsine, either the one for dry skin
or the one for spot-prone skin
which has become dry due to acne treatment. Your dermatologist is right, these are superficial dryness lines not permanent wrinkles, as you say retinoids are used for smoothing skin. Side effects should stop within a month of completing your course. How much longer do you have on the accutane?
