Medical Portable 308nm Laser Excimer Instrument Psoriasis Vitiligo Treatment Skin Diseases Therapy UVB Lamp Lights Therapy

The device is intended for targeted phototherapy of UVB‑responsive skin conditions such as psoriasis and vitiligo and may be used for other dermatologic conditions that respond to 308nm excimer therapy. Treatment plans and suitability should be determined by a qualified dermatologist.

The 308nm excimer delivers targeted narrowband UVB light to affected skin areas. This can reduce local inflammation and, in the case of vitiligo, stimulate repigmentation. Clinical response varies by condition, lesion size, skin type and treatment regimen.

The product description lists both home and clinical use. However, it should only be used at home under the instruction and follow‑up of a healthcare professional. A physician should prescribe the treatment parameters and monitor progress and side effects.

Treatment duration and frequency depend on the prescribed dose, skin type and condition severity. Sessions can range from seconds to minutes per spot. Always follow the dosing schedule provided by your treating clinician or the user manual.
