DPN

Dermatosis Papulosa Nigra (DPN)

What is DPN? Dermatosis Papulosa Nigra (DPN) is a benign skin condition commonly affecting individuals with darker skin tones. It manifests as small, dark bumps, primarily on the face and neck. While some people may only develop a few bumps, others can have many. These spots are not cancerous or medically concerning but can be itchy, irritating, or cosmetically undesirable. They are distinct from moles.

Appearance of DPN Bumps The bumps caused by DPN are typically small, black or dark brown, smooth, round, and flat, ranging from 1 to 5 millimeters in size. Over time, they may become rougher in appearance. Some lesions may have small flaps (peduncles) resembling skin tags. While these bumps usually appear on the face and neck, they can also develop on the upper back and chest. DPN lesions often begin in adolescence and gradually increase in size and number with age.

Causes of DPN

The exact cause of DPN is unclear, but it is believed that darker skin types and genetics play a significant role.

Treatment options for DPN

Although DPN is harmless and typically does not require treatment, some individuals may seek treatment if the bumps become itchy or too numerous. Treatment options include:

  • Scissor excision
  • Shave excision
  • Cryosurgery
  • Electrodessication
  • Curettage
  • Dermabrasion
  • Laser removal

Can DPN lesions return after removal?

DPN lesions that are removed typically do not grow back in the same spot. However, new lesions can develop over time due to the underlying genetic predisposition12. This means that while treatment can effectively remove existing bumps, it does not prevent new ones from forming in the future.

Are there any preventive measures to avoid new DPN lesions?

While there are no guaranteed methods to prevent new DPN lesions, there are some steps you can take to potentially reduce their occurrence:

Sun Protection: Protect your skin from the sun’s harmful UV rays by using broad-spectrum sunscreen with an SPF of 30 or higher, wearing protective clothing, and seeking shade12. Sun exposure can worsen the condition.

Gentle Skincare Routine: Maintain a skincare routine that avoids abrasive ingredients. Products with alpha hydroxy acids or other harsh chemicals can cause irritation and increase skin sensitivity.

Regular Monitoring: Keep an eye on your skin for any changes in existing lesions or the appearance of new ones. Consult a dermatologist if you notice any changes in size, shape, or color.

Healthy Lifestyle: A balanced diet and proper hydration can contribute to overall skin health, which might help in managing DPN.

While these measures may help, it’s important to remember that DPN is largely influenced by genetics, so new lesions can still develop over time.

While there are no specific skincare products that can completely prevent or treat DPN, certain products can help manage your skin’s overall health and potentially reduce irritation or the appearance of new lesions. Here are some recommendations:

  • Sunscreen: Using a broad-spectrum sunscreen with an SPF of 30 or higher can protect your skin from UV damage, which may help prevent the worsening of DPN lesions. Look for sunscreens that are suitable for sensitive skin and free from harsh chemicals.
  • Gentle Cleansers: Opt for mild, non-abrasive cleansers that do not strip your skin of its natural oils. Products like Cetaphil Gentle Skin Cleanser or La Roche-Posay Toleriane Hydrating Gentle Cleanser are good options.
  • Moisturizers: Keeping your skin well-hydrated can improve its overall appearance. Choose moisturizers that are non-comedogenic and suitable for sensitive skin, such as CeraVe Moisturizing Cream or Neutrogena Hydro Boost Water Gel.
  • Antioxidant Serums: Serums containing antioxidants like vitamin C can help protect your skin from environmental damage and improve its overall texture. Products like SkinCeuticals C E Ferulic or The Ordinary Vitamin C Suspension 23% + HA Spheres 2% are popular choices.
  • Avoid Harsh Ingredients: Steer clear of skincare products with alpha hydroxy acids (AHAs), beta hydroxy acids (BHAs), or other harsh exfoliants that can irritate your skin and make it worse.
  • Remember, while these products can help maintain healthy skin, they won’t prevent new DPN lesions from forming due to the genetic nature of the condition. If you have any concerns or need personalized advice, it’s always best to consult with your doctor.

How many sessions are needed to remove DPN lesions?

The number of sessions needed to remove DPN lesions can vary depending on the size and number of lesions, as well as the treatment method used. Generally, most patients require one to two sessions. An initial treatment is often followed by a touch-up session 6-8 weeks later to address any lesions that did not fully resolve with the first treatment.

What is the cost of DPN removal?

Since DPN removal is considered a cosmetic procedure, it is usually not covered by most insurances.  As for the cost, it can vary widely based on the number of lesions and the treatment method. At our office, treatment costs typically range anywhere from $300 to $500 depending on the number of lesions.  

What are the potential risks or side effects of DPN removal?

Removing DPN lesions can be very effective, but there are potential risks and side effects associated with the various treatment methods. Here are some of the most common ones:

  • Hyperpigmentation: Darkening of the skin in the treated area.
  • Hypopigmentation: Lightening of the skin in the treated area.
  • Scarring: Formation of scars, which can be more pronounced in individuals with darker skin13.
  • Keloid Formation: Raised, thickened areas of scar tissue that can develop at the site of treatment1.
  • Infection: Although rare, there is a risk of infection at the treatment site3.
  • Pain and Discomfort: Some treatments can cause pain or discomfort during and after the procedure.
  • Crusting and Erosion: The treated area may develop a crust or superficial erosion that heals over time.

It’s important to discuss these potential risks with your doctor to determine the best treatment option for you and to ensure proper aftercare to minimize complications.  If you have any concerns about the appearance of your skin and ready to schedule your appointment, please contact us at 720-818-0533 or visit us on the web at aestheticsandmedicallasers.com.
