psoriasis is a chronic skin condition that speeds up the life cycle of skin cells, causing them to build up rapidly on the surface of the skin. these extra skin cells form scales and red patches that are itchy and sometimes painful.
psoriasis is a persistent, long-lasting (chronic) disease. there are several types of psoriasis, including plaque psoriasis, nail psoriasis, guttate psoriasis, inverse psoriasis, and pustular psoriasis.
the cause of psoriasis isn't fully understood, but it's thought to be related to an immune system problem with t cells and other white blood cells, called neutrophils, in the body.
symptoms vary depending on the type of psoriasis but can include red patches of skin covered with thick, silvery scales, dry, cracked skin that may bleed, itching, burning, soreness, and swollen and stiff joints.
there's no cure for psoriasis, but various treatments can help manage the symptoms. these may include topical ointments, light therapy, and systemic medications.
