How it works
The KN‑4003BL corded lamp delivers carefully controlled ultraviolet B light at a fixed 311 nm wavelength, covering a 5 cm by 2 cm treatment window. This targeted exposure supports management of plaque psoriasis and vitiligo at lip‑tip areas, as well as dyshidrotic eczema and stasis dermatitis, helping alleviate symptoms and improve appearance. Because this is a corded model, it uses a fixed power source and offers a lamp intensity around 0.6–2.5 mW/cm2. A comb attachment supports scalp treatment, and you should hold the device at about a 3 cm distance for consistent results.
What to expect
