Product Overview
The 308nm UVB Light Pen is a compact targeted phototherapy device designed to deliver narrowband UVB light to small skin areas. It is commonly used in dermatology-related light therapy applications for localized skin conditions.
How 308nm UVB Light Therapy Works
The device emits 308nm narrowband UVB light that interacts with skin cells and immune pathways. This wavelength is widely used in dermatology for targeted phototherapy treatments.
- Delivers targeted UVB phototherapy to small skin areas
- Supports localized immune response modulation
- Used in clinical dermatology light therapy protocols
- Non-invasive, controlled light exposure system
Clinical Applications of 308nm UVB Therapy
- Vitiligo – supports repigmentation of affected skin areas
- Psoriasis – helps reduce plaques and inflammation
- Atopic Dermatitis – supports relief of localized symptoms
- Pityriasis Rosea – may help reduce lesion duration
Clinical Evidence & Research Overview
308nm UVB phototherapy has been widely studied in dermatology for its role in treating localized inflammatory and autoimmune skin conditions. Research supports its use as a targeted narrowband UVB treatment option.
Key Clinical Findings
- Improvement in vitiligo repigmentation in treated areas
- Reduction in psoriatic plaque severity
- Improvement in localized eczema symptoms
- Modulation of inflammatory skin response

Mechanism of Action
308nm UVB light works by interacting with skin immune cells and modulating inflammatory responses. It is used in targeted dermatological phototherapy to improve localized skin conditions.
- Localized immune regulation
- T-cell activity modulation
- Supports repigmentation processes (vitiligo)
- Reduces inflammatory response in skin lesions
Safety Information
- Avoid direct eye exposure
- Use protective goggles during operation
- Do not exceed recommended exposure time
- Not suitable for children
- Consult a healthcare professional before use
