Given that you've tried all these things, you should see a dermatologist. You may have a medical condition like exema or psoriasis or something. It can be treated but you may need a prescription. Even if it's just especially dry skin that's not responding to the stuff you tried, a dermatologist can advise you what to use and might have something that's better than the usual over the counter options for you.
