Professional 308nm UVB Phototherapy for Targeted Skin Treatment
The KN-4003B1 308nm UVB Phototherapy Device is an advanced handheld phototherapy system developed to provide targeted ultraviolet B (UVB) light therapy for localized skin conditions. Using 308nm narrowband UVB LED technology, the device delivers controlled ultraviolet light to affected areas while minimizing exposure to surrounding healthy skin.
Its compact, lightweight design makes it ideal for both home users and healthcare professionals treating smaller or difficult-to-reach areas such as the face, hands, elbows, knees, scalp margins, and around the eyes (with appropriate eye protection and professional guidance). The rechargeable lithium-ion battery provides cordless convenience, while dose and time treatment modes allow customised treatment protocols.

What Is 308nm UVB Phototherapy?
308nm narrowband UVB phototherapy is a recognised treatment used by dermatologists for selected inflammatory and pigmentary skin disorders. The specific wavelength targets affected skin while limiting exposure to surrounding tissue, making it particularly useful for localised lesions. Treatment plans should always be determined by a qualified healthcare professional.
Common Clinical Applications
Under the guidance of a qualified healthcare professional, the KN-4003B1 may be used as part of treatment plans for:
- Vitiligo
- Psoriasis
- Eczema (atopic dermatitis)

Treatment suitability varies from person to person and should always be assessed by a dermatologist.
Precision Treatment for Small Areas
The compact treatment head allows accurate application to difficult treatment sites including:
- Face
- Hands
- Fingers
- Elbows
- Knees
- Feet
- Around the hairline
- Small localised lesions
The focused treatment area helps minimise unnecessary UV exposure to surrounding healthy skin.
Two Professional Treatment Modes
Dose Mode
Allows treatment to be delivered according to a prescribed UV energy dose for greater consistency and accuracy.
Time Mode
