I really need help with my skin. I generally have dry flaky skin all over, but my face is just getting worse and worse. It tends to be red, tight, flaky, rough and feels really thin, like tissue paper. I have quite sensitive skin, so there are plenty of products that just make me itch, but I have tried so many things and nothing seems to work (and I now don't recall all the things I have tried). They either soak in, but then make no difference, or they sit on top like a layer of grease. What should I be looking for?
