Excimer Laser Therapy for Psoriasis

At Alpha Dermatology, we provide advanced excimer laser therapy—a precise, state-of-the-art phototherapy option for patients with mild to moderate psoriasis, particularly when plaques are localized or resistant to other treatments.

This FDA-cleared treatment uses a targeted 308 nm excimer laser to deliver high-intensity narrowband UVB light directly to affected skin areas, such as the elbows, knees, scalp, palms, soles, or other stubborn spots. By focusing energy only on psoriatic plaques and sparing surrounding healthy skin, it allows for higher, more effective doses than traditional full-body phototherapy—often resulting in faster clearance, reduced scaling, redness, and thickness, and longer periods of remission.

Clinical studies show many patients achieve significant improvement (75% or greater clearance) in as few as 6–10 sessions, with treatments typically lasting just 5–15 minutes each, performed 2–3 times per week in our office. It's especially beneficial for difficult-to-treat areas like the scalp, where topical therapies may be challenging.

Key Benefits:

- Highly targeted precision minimizes unnecessary UV exposure to unaffected skin, reducing potential side effects

- Quick, convenient in-office sessions with no downtime

- Excellent for localized or resistant plaques, including scalp psoriasis

- Well-tolerated; common mild side effects (like temporary redness or blistering) are usually short-lived

- Insurance coverage: Excimer laser therapy for psoriasis is usually covered by most major insurance plans, including Medicare, when medically necessary (prior authorization may be required—our team assists with this process)

Our experienced, board-certified dermatologists perform a thorough evaluation, including a test dose to determine your optimal starting energy level, ensuring safe and personalized care. This non-systemic option complements other treatments and helps patients achieve clearer, more comfortable skin without daily topicals or systemic medications in many cases.
