(HealthDay News) -- Psoriasis is a chronic condition that causes red, scaly, itchy patches on the skin.

While there is no cure, psoriasis can be controlled with these common treatments, listed by the National Psoriasis Foundation:

• Topical ointments and creams, including salicylic acid and topical steroids.
• Lotions, bath solutions and other nonprescription topical preparations to help soothe symptoms and reduce scaliness.
• Light therapy, including UVB and lasers.
• Prescription systemic medications, a term used to describe drugs that affect the entire body. These drugs are usually reserved for people with moderate-to-severe cases.
