Psoriasis is an incurable chronic autoimmune disorder of the skin that causes patches of thick, flaky, scaly skin, mostly around the scalp, knees, and elbows, though any skin surface may be involved.

The exact cause of psoriasis is not clear, but it isn’t contagious.Read more: What Is the Best Treatment for Psoriasis? Article

Psoriasis is a non-contagious skin disease in which the skin cells grow in numbers faster than normal, producing rashes on the body.

The exact cause of psoriasis is not completely understood. It appears to involve an interplay between a person’s genes, immune system and environment.
