What is Dermatosis Papulosa Nigra

Dermatosis papulosa nigra is a benign cutaneous that is common in Dark skinned people. Dermatosis is usually characterized by many small hyperpigmented, asymptomatic papules on the face of adult Dark skinned people.

What causes Dermatosis Papulosa Nigra?

Dermatologists are not sure what cause Dermatosis Papulosa Nigra but one possibility is that the hair follicle doesn't develop properly and it is likely to be connected to a genetic you have which could run in family history.


To have Dermatosis Papulosa Nigra treated you have to have every spot touched with a fine electric instrument. The treatment stings or feels hot for a few second and then goes away. There is no bleeding, the area can hurt for 1 to 2 hours after the treatment and the skin should be healed between 7 to 10 days after the treatment. After the treatment there is a chance that the spots grow back because it is normal to develop new spots over time.

Symptoms of Dermatosis Papulosa Nigra:

  • Many firm, smooth raised brown or black spots occurring on the cheeks, forehead
  • The spots can also happen around the neck,chest and back.
  • Mild: less than 10 spots.
  • Moderate: 10 to 50 spots.
  • severe: more than 50 spots.


There is no prevention of Dermatosis Papulosa Nigra because it is a development issue with the hair follicle not properly developing and is also linked to family history and genetics.

What Happens In The Future?

In the future the spots stay as they have always been, unless you have had treatment done to your spots because then there is a likely chance that you have new spots grow back because this is very normal to have happen.
