How does psoriasis affect the skin?

Psoriasis is a skin disease that causes itchy, red, and scaly patches, most commonly on the elbows, knees, scalp, and trunk. Psoriasis is a common, chronic skin disease. It tends to go through cycles - flares for a few weeks or even months and then subside for a while or goes into remission. Timely and appropriate treatment can help to manage the symptoms of psoriasis effectively.

• Injuries to the skin
• Weather, especially cold or dry conditions
• Stress
• Smoking
