Aspen, Colo. – An expert shared cases involving laser treatment for atrophic and hypertrophic scarring at the summer Cosmetic Bootcamp (CBC).
For atrophic scars, said Tina S. Alster, M.D., traditional pulsed CO2 lasers can provide significant, durable improvements with just one treatment. To avoid post-treatment mismatches in skin color or texture, she recommended treating entire cosmetic units. With microneedling, she said, a small area of atrophic scars within a cosmetic unit can be treated without worrying about color mismatches, provided patients do not have pre-existing dyschromias there. She is director of the Washington Institute of Dermatologic Laser Surgery and clinical professor of dermatology at Georgetown University in Washington, D.C.
For a patient with hypertrophic scars and keloids resulting from CO2 laser burns created by another practitioner, Dr. Alster initially prescribed topical agents to address dyschromia. “Then I applied the pulsed dye laser on her erythematous, hypertrophic scars, followed immediately by microneedling.” The patient achieved very good results with just one treatment, she said.
