Although it may vary, nurses may be hired directly out of school to work in dermatology. If you want to continue and become a nurse practitioner, additional education is needed. Requirements to get into a nurse practitioner program vary, but usually a bachelorâs of nursing degree is needed. Most nurse practitioner programs are between two and four years, and a masterâs degree is awarded after graduation. An optional certification is available through the Dermatology Nurse Certification Board. The requirements to become certified include a minimum of 2000 hours of experience working in dermatology.
