DPN (Dermatosis Papulosa Nigra)

DPNs are small, brown or black bumps that are sometimes mistaken for moles. It is felt that a combination of heredity, ageing and exposure to the sun are factors in the development of DPNs. These lesions are found specifically on dark skin types, particularly skin types 5 & 6. They are also commonly called “Morgan Freeman spots”. They can increase in size and number with time.

Classification & Symptoms:

DPN's can be 1–5mm in size. They are firm, smooth and raised dark brown to black bumps. They occur on the cheeks, around the eyes and on the forehead. These bumps may also appear on the neck and trunk.

How are DPNs treated?

Since DPNs are non-cancerous, they do not have to be treated as they are not life threatening. They do, however, increase in number and size with age and it is for these reasons that patients want them treated and removed as they are difficult to cover up or hide (particularly in men who generally do not wear make-up).

At Skin Renewal, DPN s are successfully removed with the small spot size 3mm of the long pulsed Nd: YAG laser. This procedure is generally well tolerated and healing generally occurs within one to two weeks.

Side effects of removal may include light or black skin discolourations which usually fade rapidly especially if the skin is pre-treated correctly with a skin pigmentation inhibitor or skin treatment preparation cream.
