Dermatosis papulosa nigra, commonly known as DPN, consists of small, harmless dark bumps that usually appear on the face, neck, and chest, particularly on darker skin tones. While completely safe, many people prefer to remove them for smoother skin, and advanced electrolysis is an ideal, gentle treatment. A tiny probe touches each spot and delivers a precise electrical current to treat the bump directly at the skin surface. The spots then dry up into tiny crusts and naturally flake off over a few days, leaving your skin clear and smooth.
