A Per Diem Dermatologist is a physician who works on an as-needed basis, rather than full-time or on a fixed schedule. These dermatologists provide medical and cosmetic skin care, diagnosing and treating conditions such as acne, eczema, and skin cancer. They typically work in hospitals, clinics, or private practices, filling in for other dermatologists or handling patient overflow. This role offers flexibility, allowing doctors to choose when and where they work. It’s a great option for those seeking work-life balance or supplemental income.
