Psoriasis strikes most commonly in patients between 15 and 35 years of age. Psoriasis causes skin cells to grow more quickly than usual. Naturally, the body forms new skin cells monthly to replace cells that have flaked away. However, psoriasis causes the formation of new cells within a matter of days rather than weeks. This causes the dead cells to gather on the surface of the skin, causing red patches that are thick and itchy, as stated by Healthline.

Psoriasis often looks like dermatitis or ringworm, and only a doctor is able to confirm a psoriasis diagnosis, but most of the time, that is possible through a visual examination. In some cases, doctors need to run a skin biopsy to rule out other possible ailments. Treatment using topical ointments or creams is designed to cut down on irritation and inflammation. Light therapy may be used to slow down new skin cell growth. Oatmeal baths soothe irritation, and moisturizing dry skin right after a shower or bath often decreases attacks, reports Healthline.
