I'm swimming in a city pool, and have a minor case of psoriasis. It's just a patch of red skin on each knee, but scares people because it looks inflamed (they think infection).

Cover-up creams seem to create as much trouble as they correct. I'm thinking of a waterproof wrap, like an ace bandage. I have a full body suit but don't want to use it. (Besides, it's not for the pool, it's for diving.) Do they make arm or leg covers?

PS If you had a burn scar or a healing surgical wound you wanted to cover or protect, It'd be similar.
