Portable Excimer Laser Phototherapy System UVB 308nm LED Laser Machine Vitiligo Psoriasis Laser Beauty Equipment

It is a compact excimer (XeCl) UVB 308nm laser device designed to deliver focused phototherapy for skin conditions such as vitiligo and psoriasis. It offers adjustable treatment time, continuous work mode and a maximum spot size of 16 cm².

The 308nm UVB excimer wavelength selectively targets affected skin to reduce local immune activity and stimulate repigmentation (in vitiligo) or reduce inflammation and scaling (in psoriasis). Treatments are delivered in controlled pulses or continuous mode to affected areas.

Key specs include: model P325, XeCl lamp, wavelength 308nm, optical power density 30 mW/cm² ±20%, fluence range 30–4200 mJ/cm², spot size up to 16 cm², treatment time 1–140 seconds, and preset erythema test doses (3s/6s/9s/12s/15s/18s).

The device is compact and user-friendly, and it may be used at home by some patients. However, phototherapy should be used under a dermatologist's guidance, and users must be trained on settings, safety (including eye protection), and treatment protocols.

Typical treatment frequency is commonly 2–3 times per week, but exact schedules and cumulative dose depend on the condition and skin response. Some patients see improvements within weeks; others require several months. Follow your clinician's protocol for best results.

The erythema test dose is a short, graded exposure used to determine the minimal skin reaction (sensitivity) to the device. It helps establish a safe starting dose and reduces the risk of burns or excessive redness.

Always use appropriate protective eyewear for patient and operator, avoid exposing uninvolved skin or eyes, do not treat over tattoos or suspicious lesions, and follow contraindication guidance. Ensure the treatment area is clean and avoid photosensitizing medications unless advised by a physician.

Contraindications generally include active skin cancer or suspicious lesions in the treatment area, known photosensitivity disorders, use of systemic or topical photosensitizing medications without clearance, and pregnancy—consult a healthcare provider before use.

Common short-term effects include mild erythema (redness), itching, or temporary discomfort at treated sites. Rarely, blistering or hyperpigmentation/hypopigmentation can occur if doses are too high. Report persistent or severe effects to a clinician.

The device provides a maximum spot size of 16 cm² and is used to treat discrete patches. Clinicians typically define borders of affected skin and move the applicator to cover targeted areas while avoiding healthy surrounding skin.

Routine maintenance includes cleaning the applicator per the manual, inspecting for damage, ensuring vents are free of dust, and following manufacturer instructions for lamp checks and replacement. Refer to the product manual or supplier for lamp life and servicing schedules.

Basic training is recommended for safe and effective use, including understanding dose settings, performing erythema tests, safety protocols, and recognizing adverse reactions. Professional clinics typically have trained staff; home users should be instructed by a clinician or supplier.

The device is marketed for skin rejuvenation and beauty enhancement in addition to medical indications. Results vary; discuss goals and expected outcomes with a qualified practitioner before cosmetic use.

The unit measures approximately 27 x 24 x 26 cm and the single package gross weight is about 9.0 kg, making it relatively compact and portable for clinic or home use.

Warranty coverage and regulatory certifications may vary by supplier and region. Check with the vendor or manufacturer (OEM/ODM) for details on warranty, CE/FDA or other approvals, and local compliance before purchase.
