What is psoriasis?
Psoriasis is a non-contagious disease of the skin in which the skin cells grow in numbers faster than normal, producing rashes on the body. Normally, the cells on the surface of the skin are shed as new cells grow beneath. In psoriasis, the swift build-up of skin cells collects on the surface of the skin as scales or plaques.
