Portable UVB Therapy 308 Excimer Phototherapy Excimer Laser 308nm Psoriasis Skin Care Product Eximer Laser Vitiligo Treatment

The device is intended for targeted phototherapy of conditions such as psoriasis and vitiligo, using a 308nm UVB wavelength to treat affected patches on the body and face. It is designed for home, spot-based therapy rather than whole-body treatment.

The device operates at a 308nm wavelength. The manufacturer lists the light source as LED while delivering excimer-type 308nm phototherapy for targeted UVB treatment.

The device can be used on facial areas, but you must avoid direct exposure to the eyes and wear appropriate UV protective goggles. Do not aim the light at the eyes, eyelids or mucous membranes. Consult your physician for guidance on safe facial use.

Treatment frequency and duration vary by condition and individual tolerance. Typical home protocols for 308nm phototherapy are short sessions (seconds to a few minutes) multiple times per week, but you should follow the included user manual and your clinician's recommendations for dose, frequency and progression.

Possible side effects include temporary redness, itching, mild burning, blistering or changes in pigmentation at the treated site. If you experience severe pain, blistering, or signs of infection, stop use and seek medical care. Always consult your healthcare provider before starting therapy.

Do not use if you have a known sensitivity to UV light, are taking photosensitizing medications, have a history of skin cancer in the treated area, or are pregnant without medical advice. Children and immunocompromised patients should only use it under medical supervision. Check with your healthcare provider if you have any concerns.

No — the device is not waterproof. Keep it dry, avoid using it on wet skin, and do not submerge it in water or expose it to heavy moisture.

Turn off and unplug the unit before cleaning. Wipe the exterior and treatment window with a soft, dry or slightly damp cloth; avoid harsh solvents and do not immerse in water. Store in a cool, dry place away from direct sunlight and extreme temperatures.

Response times vary by condition, severity and individual. Some users may notice improvement in weeks, while others may need several months of regular treatments. Follow your clinician's plan and the device's dosing schedule for best results.

No. This device is a home-use therapy tool and should complement — not replace — professional medical care. Consult a dermatologist for diagnosis, treatment planning and monitoring, especially before beginning phototherapy.
