Suggest Medication For Dry Skin

i used the clearasil product where you put it on eveniong and morning and wash it immediately of again, within a few hours o fusing it my skin became dry then after applying vaseline, it felt ok, but got redder as the night went on, then the next day i noticed a slight burning feeling and a red patch on my face, (cheeks and forehead), and so i washed my face and have stopped using any cream on my face, and now as the night has gone again, again the redness has got worse and the pain has become increasingly worse, so i have started using e45 cream, and was wondering if cortusone would be a product from the pharmacy i should use or any help u can offere please on to what the problem is, and how to treat it quickly and properly.
