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. It treats both the body and scalp and includes UV glasses, a power cord and adaptor, and a user‑friendly manual. The lamp life is up to 500 hours and a 3 year warranty accompanies the device.

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.
