308nm UVB LED Light Therapy Device (SQ1DJ1) For Skin Treatment

308nm is a specific narrow-band UVB wavelength shown to be effective for treating photoresponsive skin disorders. It provides targeted UVB energy that can reduce inflammation and stimulate repigmentation or clearing in conditions such as vitiligo and psoriasis while minimizing off-target wavelengths.

The device is intended for phototherapy of photoresponsive skin disorders, most commonly vitiligo, psoriasis and eczema. It is designed for localized, targeted treatment of affected skin areas under professional guidance.

The device is designed for use by professional dermatologists and healthcare providers. If used by patients, it should be done only under the direct instruction and supervision of a qualified clinician.

The treatment head covers an area of approximately 9 cm², providing focused, localized therapy suitable for small patches such as lesions on the face, hands, or other targeted sites.

The device allows adjustable doses from 0 to 5000 mJ. Treatment time can be calculated with the formula: time (seconds) = dose (mJ/cm²) ÷ intensity (mW/cm²). With an intensity of 16 mW/cm², a 1000 mJ dose would require about 62.5 seconds (1000 ÷ 16 = 62.5). Always follow the dosing protocol prescribed by the treating clinician.

Typical recommendation is every second day (every other day). Clinical protocols vary by condition and patient response; patients should follow the treatment schedule prescribed by their dermatologist and maintain consistency for best results.

The product includes UV protective goggles and covering pads. Always wear the provided goggles to protect eyes and use covering pads to shield surrounding skin. Avoid direct eye exposure and cover non-treated skin as directed.

Common short-term effects can include redness (erythema), mild burning, itching or temporary hyperpigmentation. Overexposure can cause blistering. Long-term UV exposure carries risks such as photoaging and a potential increased risk of skin cancer; therefore treatments should be prescribed and supervised by a healthcare professional.

Patients with known photosensitivity disorders, those taking photosensitizing medications, active skin infections or suspicious lesions, or a history of photosensitive malignancy should avoid use unless cleared by a physician. Although phototherapy is used in children and during pregnancy in some cases, use should be determined by a clinician on a case-by-case basis.

Clean the treatment area before therapy. For vitiligo, use warm water to remove oil and makeup. For psoriasis, gently remove scales using lightly salted warm water. Do not apply topical products that increase photosensitivity unless instructed by the clinician.

The device has a built-in battery for portable use and supports AC input of 100–240V, 50–60Hz for worldwide compatibility. Refer to the user manual for battery runtime, charging procedures and charging times.

The LED light source is rated for up to 3000 hours. Maintain the device by keeping the treatment window and goggles clean with a soft cloth, storing it in a dry environment, and avoiding impact or immersion in liquids. Do not attempt to open or service the unit; contact authorized service for repairs.

First check that the device is charged or connected to power and that any power switches are on. Ensure the treatment window is clean and unobstructed. If the problem persists, contact the supplier or authorized service center for troubleshooting and repair. Do not attempt internal repairs.

Regulatory requirements vary by country. The device is intended as a medical phototherapy instrument typically used in clinical settings, so check local regulations and supplier terms; many regions require a prescription or professional supervision for medical phototherapy devices.

Detailed dosing protocols, charging instructions, safety guidance, and warranty/after-sales information are provided in the product user manual and by the distributor. For clinical protocols and individualized dosing, consult a qualified dermatologist or healthcare provider.
