Dermatology nurse practitioners (DNPs) work with dermatologists to treat patients with skin conditions. As a DNP, your responsibilities may vary, depending on your area of specialization. For example, pediatric DNPs primarily treat patients under 18, while cosmetic DNPs treat older teens and adults. As a surgical DNP, you assist with the surgical removal of skin cancer. Your job duties as a dermatology nurse practitioner include consulting with patients, diagnosing and treating skin issues, and performing procedures such as mole removals and skin peels.
