Description

Psoriasis is a chronic immune-mediated inflammatory condition that speeds up skin cell turnover, causing cells to build up on the surface faster than they can shed. This results in thick, scaly patches called plaques, most often on the elbows, knees, scalp, and lower back, though psoriasis can also affect the joints and nails.

Causes

An overactive immune system speeds up skin cell production; genetics, stress, infections, and certain medications can all trigger flares.

Prevention

Managing stress, avoiding known personal triggers, moisturizing regularly, and limiting alcohol can help reduce flare frequency.

Treatment Options

Topical corticosteroids and vitamin D analogues, light therapy (phototherapy), and for moderate-to-severe cases, oral or biologic systemic medications.

Myths vs. Facts

Myth: Psoriasis is contagious. Fact: It's an autoimmune condition, not an infection, and cannot be spread through skin contact.

When to See a Dermatologist

If you develop persistent, scaly patches, or notice joint pain or stiffness alongside skin symptoms.
