What is psoriasis?
Psoriasis is a chronic skin condition that occurs when the immune system causes skin cells to grow too quickly, leading to thick, scaly patches called plaques. These plaques can vary in color, ranging from red, white, or silvery. They often show up on the elbows, knees, scalp, or lower back—but they can appear anywhere on the body, including the nails. Some people notice dandruff-like flakes on the scalp or rough spots that crack and bleed. In more severe cases, it can affect the joints or cover large areas of the body.
It's common to mistake it for eczema or dermatitis, but a dermatologist or advanced practice clinician (APC) can help identify the condition. "Psoriasis is a long-term condition, but with the right diagnosis and a personalized treatment plan, most people can manage it effectively," says Saba Zabetian, MD, Dermatology at ARC Georgetown.
What causes psoriasis?
There's no single cause of psoriasis, but the condition is linked to an overactive immune system and genetics. Environmental triggers can include stress, cold weather, infections, certain medications, or skin injuries like cuts or sunburns. People with any skin type can get psoriasis.
Who is at risk for psoriasis?
Risk factors include:
• Family history of psoriasis
• Smoking
• Obesity
• HIV or strep infections
• Heavy alcohol use
• Certain medicines, such as those for high blood pressure (beta-blockers), bipolar disorder (lithium), and medicines for malaria
• High stress levels

When to see a dermatology specialist
If you have rough, scaly patches, a persistent rash, or flaky scalp that doesn't improve with over-the-counter products, it's a good idea to see a dermatologist or APC. They can help determine if it's psoriasis or another skin condition and recommend the best treatment to help you heal. Treatments may include creams, light therapy, or medication.
"You don't have to live with painful or irritating skin—today's treatments for psoriasis are better than ever," says Dr. Zabetian "We can help you find relief and get back to feeling like yourself."
