While many people have experienced a skin issue or two in their lifetime — a random acne breakout, an itchy rash from too-tight pants, or even a funky lookin’ yellow toenail — most of us don’t automatically think of psoriasis when something out of the norm crops up. “Often times patients will come into the office with a skin rash and not know what’s going on,” says Suzanne Friedler, MD, a dermatologist in New York City.
Psoriasis is a chronic disease that develops when a person’s skin cells grow too quickly (they form in days rather than weeks) due to faulty signals from the immune system. The body doesn’t shed these cells, so they pile up on the surface of the skin which causes patches of psoriasis to appear. Learn more in Psoriasis: Your GoodRx Guide.
