It is a handheld, portable light therapy device that emits a peak wavelength of 308 nm (UVB) designed for home-use management of certain skin conditions such as psoriasis and vitiligo. Model number UL-01; Class II medical instrument.
308 nm UVB (often called excimer or narrowband UVB) can reduce inflammation and alter immune activity in affected skin, which may improve symptoms of psoriasis and repigmentation in some cases of vitiligo. Individual results vary and it is intended as a symptomatic management tool, not a guaranteed cure.
The device is designed for home use and meets safety standards (ISO13485, ISO9001, SFDA as supplied). However, safe use requires following the user manual, wearing appropriate eye protection, avoiding overexposure, and using the device under the guidance of your healthcare provider.
You should consult a dermatologist or healthcare professional before starting treatment. Many users require an individualized treatment plan (dose, frequency, duration) based on skin type and condition; your clinician can advise whether prescription or supervised use is necessary.
Treatment frequency and session length vary by condition, skin type and clinician guidance. Common clinical protocols often involve multiple sessions per week, but session times can range from seconds to minutes. Always follow the device manual and your healthcare provider's prescribed regimen; start with a test patch and the lowest recommended exposure.
Wear the recommended eye protection, protect uninvolved skin, avoid treating moles or suspicious lesions, do not use on open wounds or mucous membranes, and stop use and contact your clinician if you experience severe redness, blistering, or other concerning reactions.
People with a history of photosensitivity disorders, those taking photosensitizing medications, people with active skin cancer or lesions suspicious for cancer, and anyone advised by their physician to avoid UV therapy should not use this device without medical clearance. Pregnant or breastfeeding individuals should consult their healthcare provider.
Mild side effects may include redness, itching, dryness or temporary burning. More severe reactions (blistering, severe pain, signs of infection) are possible with overexposure. If you experience severe or persistent side effects, discontinue use and seek medical advice.
The device is intended for use on various skin types, but efficacy, tolerance and recommended doses differ by skin phototype. A dermatologist should determine the safest and most effective protocol for your skin type.
