The 308nm wavelength is widely recognized as one of the most effective options for treating vitiligo and psoriasis. It targets lesions accurately, promotes T-cell apoptosis, supports immune balance, stimulates melanocyte activity, evens skin tone, and aids in wound healing.
【Wide Application Range】This advanced 308nm UV phototherapy lamp is suitable for a wide range of persistent skin conditions. It is ideal for vitiligo, psoriasis, eczema, dermatitis, leukoderma, atopic dermatitis, folliculitis, acne, mycosis fungoides, heat rash, and scalp psoriasis. A convenient home-use UVB therapy solution designed to clear lesions and help reduce recurrence.
【Adjustable Modes & Precision Targeting】Featuring a 46×46mm ±10% irradiation area, the device includes 5 food-grade silicone shade covers for accurate and focused treatment on different skin areas. It supports both dose mode and time mode for customized therapy. Energy dose range: 0–5 J/cm²; intensity range: 5–40 mW/cm² (both adjustable). Treatment sessions can be as short as 4 minutes, 3–4 times per week per area.
【Complete Package & Reliable Support】Package includes: 1× Main Device, 1× Protective Glasses, 5× Shade Covers, 1× Carrying Bag, 1× User Manual, and 1× Power Adapter. If you have any questions regarding our phototherapy device, please feel free to contact us—we will provide a satisfactory solution.
How 308nm UVB Light Therapy Works
1. Targeted Therapeutic Wavelength
The 308nm wavelength falls within the UVB spectrum (280–320nm) and is considered a narrowband UVB (NB-UVB) light. By concentrating therapy at a precise 308nm wavelength, it maximizes therapeutic benefits while minimizing exposure to unnecessary or potentially harmful UV radiation.
2. Interaction with Skin Cells
308nm UVB light penetrates the epidermis and is absorbed primarily by keratinocytes, triggering several beneficial biological responses:
DNA Repair Activation: Helps initiate natural DNA repair processes, beneficial in conditions involving abnormal cell growth or immune dysfunction.
Immunomodulation: Regulates overactive immune responses that cause inflammation in many skin disorders.
Reduced Hyperproliferation: Slows excessive skin cell turnover, particularly helpful for psoriasis and similar conditions.
3. Therapeutic Effects Across Skin Conditions
308nm UVB phototherapy has been proven effective in managing a range of dermatological conditions, including:
Psoriasis: Reduces plaques, scaling, and inflammation by normalizing cell growth.
Vitiligo: Promotes repigmentation by activating melanocytes.
Atopic Dermatitis (Eczema): Relieves inflammation and itching through immune modulation.
Alopecia Areata: Encourages hair regrowth by influencing immune cells that attack hair follicles.
4. Highly Localized Treatment
The 308nm wavelength enables precise, targeted irradiation, allowing treatment to be focused only on affected areas. This minimizes damage to surrounding healthy skin and reduces the likelihood of side effects, making the therapy both effective and safe for localized lesions.
Application of 308nm UV Light Therapy Device:
The 308nm UVB light therapy device is designed for targeted phototherapy and is suitable for managing a wide range of dermatological conditions. The 308nm wavelength allows precise irradiation of affected areas while minimizing exposure to surrounding healthy skin.
1. Pigmentation Disorders
308nm UVB therapy is widely used in treating pigment-related skin conditions, including:
Vitiligo (supports repigmentation)
Pityriasis alba
Leukoplakia / Congenital leukoplakia
Chloasma, liver spots, freckles
Nevus of Ota
2. Autoimmune & Inflammatory Skin Diseases
The device helps regulate immune response and reduce inflammation, suitable for:
Psoriasis / Palmoplantar pustulosis
Eczema / Atopic dermatitis
Neurodermatitis
Ichthyosis

Instructions for Use – 308nm Light for Vitiligo Phototherapy
1. Preparation Before Treatment
Clean and dry the treatment area to ensure the skin is free from lotions, creams, or makeup.
Wear the provided protective goggles throughout the entire session.
Select the appropriate shade cover to precisely target the depigmented area and protect surrounding healthy skin.
2. Initial Treatment Settings
Start with a short exposure time, typically 30–60 seconds for the first session.
Use low-dose or beginner intensity settings as described in the device manual.
Do not exceed the recommended treatment area size per session.
3. Treatment Frequency
Perform treatments 2–3 times per week, with at least 24 hours between sessions.
Avoid daily use to prevent skin irritation or overexposure.
4. Treatment Duration per Session
Depending on skin response and device settings, exposure time generally ranges from:
30 seconds to a maximum of 4 minutes per session
Increase exposure gradually based on tolerance and manufacturer guidelines.
5. Expected Results
Most users begin to see early improvement—such as mild repigmentation—within 4 to 8 weeks of consistent use.
Individual results may vary depending on skin type, lesion location, and duration of the condition.
6. After-Treatment Care
Avoid scratching or rubbing the treated area.
Keep the skin moisturized with a gentle, fragrance-free moisturizer.
Limit sun exposure for at least 12–24 hours after treatment.
7. Important Precautions
Do not treat areas with open wounds, infections, severe sunburn, or active inflammation.
If you experience blistering, excessive redness, or pain, discontinue treatment and allow the skin to recover.
Always start with lower doses, especially for sensitive skin areas (face, neck, flexures).
