Perfect for managing atopic dermatitis and encouraging hair regrowth in alopecia areata, it supports a professional yet convenient home phototherapy routine.

This 308nm UVB phototherapy device delivers targeted excimer lamp technology to affected skin areas, helping reduce inflammation and modulate immune response. Offering a treatment area of 46x46mm, it allows precise application while protecting surrounding skin. Users can adjust both dose (0-5J/cm²) and intensity (5-50mW/cm²) via an intuitive LCD interface. Suitable for psoriasis plaques, vitiligo spots, eczema patches, and alopecia areata, it comes with a rechargeable battery for cord-free sessions. Follow included safety guidelines—such as wearing UV protection glasses—for effective and secure light therapy at home. 

Designed for effective skin phototherapy, this 308nm excimer device emits narrowband UVB light to treat psoriasis, vitiligo, atopic dermatitis, and alopecia areata. It features a consistent 308nm wavelength and customizable irradiation settings (dose up to 5J/cm², intensity up to 50mW/cm²) over a 46mm x 46mm spot. The portable design includes a long-lasting battery and universal voltage support (110-240V) for easy home or travel use. Always use the included protective eyewear and shade covers to ensure safe, focused treatment. Ideal for targeted UVB therapy and skin repigmentation routines.

Optimize your skin treatment regimen with this 308nm UVB light therapy device, powered by an excimer lamp system for precise ultraviolet B delivery. It effectively addresses psoriasis scaling, vitiligo depigmentation, eczema inflammation, and alopecia areata hair loss through immune-modulating 308nm phototherapy. Adjustable energy output and exposure time allow personalized sessions based on MED test recommendations. The package includes essential accessories: UV-blocking goggles, shade covers, a user manual, and a DC power adapter. A reliable, rechargeable tool for clinical-grade home phototherapy and maintenance therapy.

Working Principle 
308nm UVB light therapy, a form of targeted phototherapy, uses a 308nm velength of ultraviolet B (UVB) light to treat skin conditions. The light is delivered via an excimer lamp and is designed to be focused on the affected areas, minimizing exposure to surrounding healthy skin.

This UVB light is absorbed by keratinocytes, T-cells, and chromophores such as DNA, promoting DNA damage and reducing local inflammation and keratinocyte proliferation.UVB alters the activity of antigen-presenting cells, reducing the proliferation of lymphocytes and impacting the production of certain cytokines involved in immune responses. 308nm UVB therapy can suppress the immune system, which is crucial in conditions where an overactive immune system contributes to the skin disease. 

308nm UVB light is effective for treating various skin disorders, including:
Psoriasis: Reduces plaques and scaling by slowing down the overproduction of skin cells.
Vitiligo: Stimulates repigmentation by activating melanocytes (pigment-producing cells).
Atopic Dermatitis (Eczema): Decreases inflammation and itchiness by modulating the immune response.
Alopecia Areata: Encourages hair regrowth by affecting immune cells that attack hair follicles.

General Guidelines for 308nm UVB Light Therapy:
1.Initial Test:
You can perform a minimal erythema dose (MED) test, which determines the lowest UVB dose that produces a slight redness on the skin within 24 hours. This helps to establish a safe starting dose.

2.Treatment Frequency:
2-1 Typically 2-3 times per week: Most treatment plans recommend using 308nm UVB light 2 to 3 times per week, with at least one day of rest between sessions to allow the skin to recover.
2-2 Not daily: Daily use is usually not recommended as it increases the risk of skin damage and side effects like burns or excessive redness.

3.Session Duration:
3-1 Start with short exposure times: The initial exposure time is usually very short, often ranging from a few seconds to a minute, depending on the MED test results.
3-2 Gradually increase: Over time, the exposure duration may be gradually increased as your skin builds tolerance, but this should always be done under medical supervision.

4.Treatment Session:
4-1 Eye protection: Always wear protective goggles to shield your eyes from UV light exposure.
4-2 Skin protection: For areas that do not require treatment, cover them with clothing or a UV-blocking material to prevent accidental exposure.

5.Duration of Therapy:
5-1 Depends on the condition: The length of treatment varies. For some conditions like psoriasis or vitiligo, it may take several weeks or even months of consistent treatment to see significant improvement.
5-2 Maintenance therapy: Once the desired results are achieved, some patients may need maintenance therapy to prevent relapse, which is usually less frequent (e.g., once a week or less).
