Psoriasis symptoms can vary from person to person, and also depend on the type of psoriasis a person has. But knowing what to expect from this condition can help you find the best ways to care for your symptoms, as well as what to discuss with your doctor.


Most people with psoriasis have plaque psoriasis—the American Academy of Dermatology (AAD) estimates that this type affects about 80 percent of people with the condition. It’s characterized by inflamed skin lesions called plaques. On lighter skin, the plaques are red; on darker skin tones, they may be dark-brown, red, or purple. Usually, there are also white or silver scales on top of these plaques.
