Has anyone actually healed their hands from contamination ocd?

My hands got pretty bad, very red and dry. I am always putting vasoline on throughout the day and before bed. Recently I feel like I really started washing less and also less throughly but they’re still very discolored compared to my forearms/wrist. I do also live in a dry climate so I know that doesn’t help.

Any advice? Obviously still cut down on the washing and maybe adjust how I wash. I could see maybe switching soap too
