Psoriasis

What It Is:

Psoriasis is a chronic autoimmune disorder that causes skin cells to multiply too quickly, resulting in raised, red, scaly patches. This rapid turnover leads to a buildup of dead skin cells on the surface, often accompanied by itching, burning, or discomfort.

The condition is linked to immune system dysfunction, where the body mistakenly attacks healthy skin cells. While its exact cause remains unclear, factors such as genetics, stress, infections, cold weather, and specific medications can trigger or aggravate flare-ups. Psoriasis most commonly appears on the scalp, elbows, knees, and lower back, though it can affect other areas as well.

What It Looks Like:

These patches are often dry, thickened, and inflamed, with a silvery-white scale on top. In more severe cases, the skin may crack, itch intensely, or bleed, leading to discomfort and increased risk of infection.

Treatment:

Topical treatments such as corticosteroids, salicylic acid, and coal tar can help reduce inflammation and scale. For more stubborn or widespread psoriasis, phototherapy (light therapy) and systemic medications like biologics or oral immunosuppressants may be prescribed by a dermatologist.
