What is the permanent treatment for DPN?

My favorite treatment for DPN are a combination of electrodessication and a light chemical peel.  DPN is a genetic and chronic minor skin condition, so you will need repeated treatments.  Fortunately once you remove the majority of lesions, you are left with maintenance treatments once or twice a year.Best of luck

You can improve these but more will come over time, they are genetic and cultural.  Electrodesiccation or light laser resurfacing help remove these with ease and without scarring but you must see an expert who understands dark/sensitive skin types.  Best, Dr. Emer.
