All appointments vary in time depending on circumstances for your visit. Each appointment will begin with a medical assistant reviewing your medical history. For general dermatology conditions and consultations, appointments can take from 10 to 20 minutes. For surgical dermatology, appointments can take from 15 to 30 minutes. For cosmetic dermatology, appointments can take from 15 minutes to an hour. Your dermatologist will discuss timing for longer appointments, such as surgeries and cosmetic procedures, prior to scheduling the appointment.
