Psoriasis is an autoimmune disease that causes raised, red, scaly patches to appear on the skin. It typically affects the outside of the elbows, knees or scalp, though it can appear on any location. Some people report that psoriasis is itchy, burns and stings.

Psoriasis treatments aim to:

• Interrupt the cycle that causes an increased production of skin cells, thereby reducing inflammation and plaque formation.
• Remove scales and smooth the skin, which is particularly true of topical treatments that you apply to your skin.
