Skin help

My skin is very dry.

Ive always had dry skin plus I have Thyroids so my skin is very very dry no matter how much lotion I wear or what type it is... so it’s very sensitive and leave horrible pimple scars, I’ve tried everything and nothing works! I get more pimples and they tend to hurt. I drink a lot of water and I can’t take it no more. I can’t find anything for me since everything is meant for people with oily face and if I wear that my face tends to break out more. What can I use? Any recommendations?
