Psoriasis

Psoriasis

A chronic skin disorder that causes skin cells to multiply up to 10 times faster than normal. This makes the skin build up into bumpy red patches covered with white scales. They can grow anywhere, but most appear on the scalp, elbows, knees, and lower back. Symptoms include flaking, inflammation, and thick, white, silvery, or red patches of skin. Psoriasis treatments include steroid creams, occlusion, light therapy, and oral medications, such as biologics.
