Recognition of Clinical Expertise

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

Dr Sin Yong's KOL Profile

Seven 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 Volnewmer monopolar radiofrequency — 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.
