Cosmetic procedures are medical procedures
The Association of Korean Dermatologists reports that most side-effect cases from cosmetic procedures involve non-specialist doctors. Choosing a board-certified dermatologist (피부과 전문의) means your injector or laser operator has four years of dermatology residency training. This page is general information, not medical advice.
