Psoriasis occurs when the life cycle of skin cells speeds up, resulting in a rapid buildup of rough, dead skin cells. These skin cells accumulate, forming thick silvery scales and dry, red patches that are sometimes itchy or painful. In some cases, pus-filled blisters appear.
Psoriasis patches can range from a few spots of dandruff-like scaling to major eruptions that cover large areas.
Though psoriasis signs and symptoms vary from person to person, psoriasis types are typically identified by their hallmark appearances. Here's a look at psoriasis photos, showing classic signs and symptoms.
