On May 8, 2022, Dr. Sang Ju Lee was invited to AMWC Asia-TDAC 2022, co-hosted by the Aesthetic and Anti-Aging Medicine World Congress and the Taiwanese Dermatological Association, where he presented 'Korea's Cutting-edge Approach on Acne and Gold PTT.'

Gold PTT is a photothermal therapy in which light-responsive gold nanoparticles are delivered into pores and heated with light of specific wavelengths, acting on the sebaceous glands that cause acne. His lecture shared the related literature, clinical cases, and parameter know-how with physicians worldwide.
