Psoriasis is a skin disease that causes itchy, red, and scaly patches. Patches often occur in the head, knees, trunk, elbows, and scalp. Psoriasis is a typical long-term disease that does not have any cure. It tends to go through cycles for several weeks or months.

What causes Psoriasis?

Psoriasis is an immune system problem. It causes the skin to regenerate faster than the normal rate. Plaque psoriasis is a typical type of psoriasis. It is a rapid turnover of cells that results in scales and red patterns.

The specific cause of the immune system malfunction is not clear. But, researchers have found that both genetics and environmental causes can trigger psoriasis. Note that this condition is not contagious.
