Best moisturizer for EXTREMELY dry skin?

I live in Indiana and it’s winter time here. My skin gets sooo dry during this time. I just always have ashy, scaley skin & it’s unattractive lol

My legs are the worst. My arms are ashy & I have a full sleeve so it’s very noticeable on my right arm.

I’ve tried EVERYTHING.... any tips?

& when I apply lotion after shower, my skin itches for like a hour & takes forever to

Soak in
