Help?

Okay so my skin has been dry for MONTHS. I’ve used different creams, I’ve changed what I use on my face, I’ve even used nothing but water to wash my face and used cream afterwards. I’ve had it to where my face is red on my cheeks from it being so dry and before it has went allllll down my face (almost like a lupus rash). Nothing I’ve been doing is helping, and I’ve tried everything I can possibly try myself. My skin is horrible on my cheeks and I don’t know what to do about it it’s actually making me really insecure.
