DPN Dermatosis Papulosa Nigra

• A benign skin condition.
   
• Characterized by small, dark papules on the face and neck.
   
• Most common in darker skin types (Fitzpatrick skin types IV–VI), especially in people of African, Asian, or Hispanic descent.
   
• Lesions are similar to seborrheic keratoses but pigmented and often multiple.
   

The Fotona laser system uses advanced Er:YAG and Nd:YAG lasers. For DPN, the Er:YAG laser is most commonly used due to its precision in superficial ablation, though Nd:YAG may sometimes be used for deeper lesions.

• Precise removal of papules with minimal damage to surrounding skin.
   
• Minimal scarring and downtime.
   
• Suitable for darker skin types, especially when handled by experienced professionals.
   
• Reduced risk of hyperpigmentation compared to cryotherapy or electrocautery.
   

• The laser ablates the raised DPN lesions layer by layer.
   
• Often done without or with minimal local anesthesia (depending on lesion size/number).
   
• Sessions are usually quick, and multiple lesions can be treated in one session.
   

• Mild redness or scabbing for a few days.
   
• Post-inflammatory hyperpigmentation (PIH) is possible but usually fades over weeks.
   
• Strict sun protection is advised post-procedure.
   
• Topical aftercare like antibiotic ointments or moisturizers may be recommended.
   

• Many lesions resolve after a single session.
   
• For numerous or larger lesions, 2–3 sessions may be necessary.
