The Remarkable Evolution Of Device-based Treatments In Dermatology

August 13, 2019

Dr. Anna Bar speaks with Dr. Kerry Purdy about how the tremendous technological evolution in device-based treatments over the past 15 years makes this an exciting time for dermatology. In this conversation from the floor of the CDA’s 2019 Annual Conference in Calgary, Dr. Bar and Dr. Purdy discuss:



  • The recent invention of microneedling with radiofrequency devices
  • Acne scarring is one of the most challenging things dermatologic surgeons face because there is no way to return skin to the unscarred state; often, it takes multiple treatments with multiple approaches that can work synergistically
  • Treatment plans must be tailored to the patient – their age, type of scarring and capacity to take downtime needs to be taken into account
  • Using a professional photographer under standardized conditions is ideal for monitoring progress in treating acne scarring
  • New indications for microneedling with radiofrequency including treating scars, postpartum striae and Hyperhydrosis
  • In purchasing a laser, it is important to test the laser in your office before purchase.

Dr. Bar is an associate professor of dermatology and a Mohs micrographic surgeon at Oregon Health & Science University. She is also the director of the fellowship program in Mohs micrographic surgery and dermatologic oncology.
