International KOL — Key Opinion Leader

Dr Sin Yong is designated an International Key Opinion Leader by CLASSYS, HIRONIC, DEKA, ALMA, FOTONA and LUTRONIC — six of the world's foremost aesthetic device manufacturers.

What Is a KOL?

Recognition of Clinical Expertise

Key Opinion Leader (KOL) designation by a medical device manufacturer is awarded to physicians who demonstrate exceptional clinical expertise, contribute to the development of treatment protocols, and advance the field through education and peer collaboration. KOLs are involved in clinical training, symposia presentations and protocol development for devices they use in practice.

Dr Sin Yong's KOL Profile

Six Manufacturers Across Three Continents

Holding KOL status simultaneously for CLASSYS (Korea), HIRONIC (Korea), DEKA (Italy), ALMA (Israel), FOTONA (Slovenia) and LUTRONIC (Korea) reflects the breadth of Dr Sin Yong's expertise across energy modalities — HIFU, RF, CO2 laser, Nd:YAG laser, Er:YAG laser and low-level laser therapy. This positions him among a very small group of aesthetic physicians in Southeast Asia recognised at this level.

CLASSYS APAC 2026 — Bangkok Symposium

At the CLASSYS APAC International Symposium in Bangkok in 2026, Dr Sin Yong presented the VF Lift protocol — his proprietary vertical facelift approach using volumetric focused energy — to an international audience of aesthetic physicians. The presentation received peer validation from Dr Davin Lim (101.skin, Sydney), one of the most cited dermatologists in the Asia-Pacific region, who specifically validated Dr Sin Yong's LCLR lipo-remodelling mechanism used in the Time Freeze Laser protocol.
