Calming irritated sensitive skin?

im on three perscriptions from my dermotologist because i have oily acne prone skin....ive been using the medications for like over a year and i just went to see her today (to ask about why my face was so red) and she said to use less of the topical treatments and find some soothing like face masks or moistorisors (not cleansing systems) to help soothe my skin because of how sensitive all the treatments make it....any suggestions???
