i remember when my hands used to look like this my doctor and parents thought i had eczema and couldnt figure out why the lotion wasnt helping but they never asked about my hand washing lol   idk if ur looking for advise i used a lot of ad ointment it should come in a kind of orangey tube putting this on at night and wearing plastic gloves over my hands as i slept really helped though its weird to go to bed with sticky gloves on pp
