What It Is:

Psoriasis is an autoimmune condition that speeds up skin cell production, leading to thick, scaly patches. Common areas include the scalp, elbows, knees, and lower back.

What It Looks Like:

It appears as raised, red patches covered with silvery scales. In some cases, it may crack or bleed.

Treatment:

Topical treatments like salicylic acid, coal tar, or corticosteroids are effective. Phototherapy and systemic medications may be necessary for severe cases.
