Psoriasis is more than a skin issue—it’s an autoimmune disorder that speeds up skin cell growth, leading to red, scaly patches, itching, and inflammation. It can also affect nails and, in some cases, the joints.
About 125 million people globally and 8 million in the U.S. live with this chronic, sometimes painful condition that can impact sleep, focus, and emotional well-being. Though its exact cause is unknown, genetics and environmental triggers play a role.
There are five main types of psoriasis, each with unique symptoms and challenges:
-
Plaque Psoriasis (most common): Dry, itchy, raised plaques with silvery scales, often on elbows, knees, scalp, and back.
-
Guttate Psoriasis: Small, teardrop-shaped spots triggered by infections like strep throat, common in children and young adults.
-
Inverse Psoriasis: Smooth, red patches in skin folds (groin, under breasts), worsened by friction and sweat.
-
Pustular Psoriasis: White, pus-filled blisters on red skin, can be localized or widespread—requires urgent care.
-
Erythrodermic Psoriasis: Rare and severe; causes widespread redness, peeling, pain, and can be life-threatening.
Psoriasis can also cause nail changes, like thickening, pitting, and detachment—often an early sign of psoriatic arthritis.
Understanding your type of psoriasis is key to managing it well. If you’re looking to learn more, keep reading or consult a healthcare provider.
