Dr. Sang Ju Lee took part in the World Congress of Dermatology (WCD) 2023 in Singapore, held once every four years, presenting posters on topics including tattoo removal, Gold PTT and skin-tightening lasers.

In particular, he introduced Asian clinical results of the R-Zero (R0) tattoo removal technique, which uses a special solution to immediately clear the bubbles formed during laser irradiation, allowing repeated passes in a single visit. He was also invited to the Cynosure APAC Summit held just before WCD, where he received a Star Award.
