How It Works

The KN-4003BL Kernel Corded Handheld UVB Lamp offers carefully controlled exposure to ultraviolet B (UVB) light at a specific wavelength of 311nm, covering a treatment area of 5cm x 2cm. This targeted exposure is beneficial for managing conditions such as plaque psoriasis, lip-tip vitiligo, dyshidrotic eczema, and stasis dermatitis, helping alleviate their symptoms and appearance.

Unlike the Cordless Handheld UVB Lamp, this model uses a corded power source, eliminating the need for charging before starting treatment. It delivers a similar lamp intensity of 0.6-2.5mW/cm2. Additionally, this device comes with a comb attachment for treating the scalp and positioning support to ensure the lamp is administered at a distance of 3cm.

The results include: 

  • Reduced Irritation
  • Enhanced Aesthetics
  • Relief from Itching
  • Restored Pigmentation
  • Improved Skin Texture
  • Inhibited Cell Proliferation
  • Enhanced Skin Barrier

UVB Phototherapy is a commonly used and FDA-approved approach to treating various skin conditions by medical professionals. You can leverage this technology with the KN-4003BL Kernel Corded Handheld UVB Lamp to find results at home.
