IstockphotoQ: I sometimes use makeup to cover up plaques. Will it make them worse?
A: Covering plaques should not make them worse. Ultraviolet light exposure does help psoriasis, however, so a little sunshine (not too much, because sunburns can make psoriasis worse) on psoriasis plaques can be a good thing.
