Published November 1, 2021

Psoriasis is a chronic inflammatory condition in which the immune system attacks the skin. It causes painful skin lesions and may also lead to psoriatic arthritis, hypertension, diabetes, chronic kidney disease, or coronary artery disease. Psoriasis treatments include topical steroids, gentle exfoliant lotions, emollients that keep the skin hydrated, ultraviolet light (phototherapy), laser therapies, vitamin A (retinoid creams), and medications (for moderate-to-severe psoriasis).
