Dermatosis papulosa nigra (DPN) is a condition of many small, benign skin lesions on the face, a condition generally presenting on dark-skinned individuals.

Exposing the skin to light from UVB lamps is the most common treatment for vitiligo. The treatments can be done at home with a UVB lamp or in a clinic.
