What it is about?
A quite barbaric word to describe something which looks like little moles.
But dont be mistaken. The Dermatosis Papulosa Nigra (DPN) is actually a Seborrehic Keratosis very common within black, hispanic or asiatic people and more generally dark skins. One of the most famous celebrities known for this concern is Morgan Freeman (he still stays very appealing !!!).
It is begnin, non-contagious and painless lesions. There is no risk of skin cancer. It mainly appears on the neck, the chest, the belly and the face areas. It measures between 1 to 3 mm but its size can change with time. It is black or brown, flat or raised. It is more important on mature skins.
Which are the causes ?
The causes of the Dermatosis Papulosa Nigra are unknown, but inherited predispositions are at stake. It is not due to a particular diet or sun exposure. According to some studies it is more usual within women than men.
Humidity would also favor DPN appearance.
How to get rid of it?
The Dermatosis Papulosa Nigra doesnt need a particular treatment unless the patient has aesthetic discomfort.
The most common treatments are :
- Nitrogen liquid
Of course, these treatments have to be done by a certified dermatologist. Most of the time, the diagnostic is done without biopsy. However, you have to be careful regarding hypopigmentation, hyperpigmentation or unfavorable healing risks.
To prevent Dermatosis Papulosa Nigra appearance, some dermatologists advise to thoroughly rub the skin with a washcloth in the shower and then with a towel after the shower. You can also regularly exfoliate your body.
As many women, I also had a DPN that I removed by a dermatologist. Its quite inconfortable the first days because of the little burn marks due to the laser. It changes to scabs and then falls after few days.
After the procedure, the dermatologist will advise you to apply morning and evening : Biseptine Spray to disinfect and Cicabio Soothing Cream to favor the healing.
