Targeted UVB therapy for skin and scalp conditions. With at‑home convenience and non‑invasive treatment, this device supports management of skin issues with FDA‑compliant technology.

How it works

The KN-4003BL emits controlled UVB light at a wavelength of 311 nm, covering a treatment area of 5 cm by 2 cm. This targeted exposure helps manage conditions such as plaque psoriasis, lip-tip vitiligo, dyshidrotic eczema, and stasis dermatitis by alleviating symptoms and improving appearance. Unlike cordless variants, this model uses a corded power source, so charging is not required before use, and it delivers a lamp intensity in the range of 0.6–2.5 mW/cm2. A comb attachment facilitates scalp treatment, and positioning support helps maintain a 3 cm distance from the skin.
