What is excimer laser treatment?
Chronic skin conditions can be hard to manage, especially when symptoms affect sensitive areas of the body. Excimer laser treatment is a type of phototherapy that uses ultraviolet B (UVB) light to target only the affected skin, leaving healthy skin untouched. It helps reduce inflammation and ease the uncomfortable symptoms common with conditions like psoriasis, vitiligo, and eczema. This noninvasive, painless option can bring relief faster than traditional light therapy, especially on areas like the face, ears, hands, and feet.
Excimer laser therapy is typically provided by general or cosmetic dermatologists, or specialized centers with trained staff and advanced equipment. Penn Medicine specialists offer this treatment to people of all ages and with many types of skin conditions.
Who is a candidate for excimer laser therapy?
This treatment is most often used to manage skin conditions like vitiligo, psoriasis, and eczema. It may be a good option if you have small, localized patches of affected skin or haven’t had success with other treatments. It may also help if you want to avoid full-body light therapy or systemic medications. Your care provider can help you decide if this option is right for your condition and skin type.
You’ll need several sessions to get the best results. Most people notice a difference after six to 10 treatments, but the exact number depends on your condition.
Laser therapy for psoriasis can help:
- Target areas of the skin affected by mild to moderate psoriasis
- Reduce inflammation and slow the growth of abnormal skin cells
- Improve the appearance of your skin and reduce symptoms
- Reach hard-to-treat areas like the scalp
Laser therapy for vitiligo can help:
- Stimulate pigment-producing cells (melanocytes) to restore skin color
- Target only the depigmented areas without affecting healthy skin
Laser therapy for eczema can help:
- Reduce inflammation by calming immune cells in the skin
- Treat specific areas without affecting healthy surrounding tissue
- Ease symptoms like itching, redness, and rash
- Support long-term control and remission of flare-ups
Excimer laser therapy may also be used to treat:
- Alopecia areata
- Folliculitis
- Granuloma annulare
- Lichen planus
- Mycosis fungoides
- Palmoplantar pustulosis
- Pityriasis alba
- Leukoderma
- Prurigo nodularis
- Localized scleroderma
What to expect during excimer laser therapy
The excimer laser is a gentle, pain-free form of light therapy. During the session, your provider will use a small handheld wand to deliver a focused beam of UVB light directly to the affected skin. The laser targets only the problem areas and leaves the healthy skin around them untouched.
The wand can be used on many parts of the body, including the face, scalp, hands, elbows, knees, and soles of the feet. Treatment usually takes just 10 to 15 minutes and doesn’t require any numbing beforehand. Most people start to see improvement after the first few sessions, which are usually scheduled two to three times per week.
Recovery after an excimer laser treatment
There’s no downtime after treatment, so you can go back to your normal activities right away. Recovery is quick, and most people don’t experience any lasting sensation or discomfort.
Possible side effects of excimer laser therapy
Excimer laser treatment is generally safe, and most side effects are mild. Some people may notice redness, blisters, small sores, or changes in skin color, like lighter or darker patches.
What are the benefits of excimer laser treatments?
Compared to traditional narrow-band UV therapy, excimer laser treatment offers several benefits:
- Fewer sessions and lower UV exposure: This lowers your risk of skin cancer and makes it easier to stick with your treatment plan.
- Precise targeting: The laser treats only the affected areas, including spots that are hard to reach.
- Customized care: Your provider can adjust the laser’s strength to match your skin and condition, which helps improve results.
