Besides diagnosing diseases, dermatologists can biopsy tissue to confirm their diagnoses, reduce the appearance of scars, prescribe medication or treatment and educate patients the proper care of their skin, hair and nails. They may refer patients to a plastic surgeon for certain types of scars, in the case of severe burns. The majority of the procedures are performed in the office as an outpatient procedure, instead of a hospital.
Dermatologists undergo an extensive education program, starting with a college degree and a medical doctorate or doctorate in osteopathy (D.O.) and ending with a one-year internship and at least a three-year residency. In their residency, these specialists learn surgical procedures to remove skin cancer and growths. They also learn to inject fillers, such as Botox, for patients desiring a younger appearance.
