Dermatology and cosmetic dermatology are 2 disciplines that share many common modalities. Combining the "disease" and "desire" aspects of dermatology will require integration on many levels. Medscape spoke recently with William Philip Werschler, MD, a renowned dermatologist and Assistant Clinical Professor of Medicine/Dermatology at the University of Washington in Seattle, about the requirements in these specialties. Dr. Werschler gives an in-depth perspective about how best to integrate these 2 types of practices, trends and avenues in this field, patient assessment, setting patient expectations, follow-up, and safety.
