A Global Stage for Singapore Aesthetic Medicine
The CLASSYS Global Customer Summit is one of the largest annual gatherings in the aesthetic device world, bringing together physicians, dermatologists, and aesthetic specialists from across the globe to Seoul — the home of CLASSYS — to share clinical protocols, device innovations, and real-world patient outcomes.
Held under the theme "Expanding Possibilities in Medical Aesthetics," the 2025 summit featured a full lecture programme, live demonstrations, and an award ceremony recognising the company's international Key Opinion Leaders. Dr Sin Yong was invited to represent Singapore on the speaking faculty.

Presenting: Secret Duo — RF Microneedling & Fractional Resurfacing
Dr Sin Yong on the main stage delivering Lecture #2 — "How To Decide Which Microneedling RF Device."
Dr Sin Yong's lecture focused on Secret Duo — CLASSYS's dual-platform system combining RF microneedling and 1550nm non-ablative fractional laser — and how he selects and combines microneedling RF devices in clinical practice. His talk compared the technology against other RF microneedling systems and explained the decision framework he uses for different skin concerns and body zones.
"The value of a microneedling RF platform is not the needles alone — it is the precision of the energy delivery, the control over each needle, and how cleanly it integrates into a wider protocol of lifting, resurfacing, and contouring."
How Dr Sin Yong Uses Secret Duo
In his Orchard Road practice, Dr Sin Yong applies the Secret Duo platform across three distinct protocols:
Luminescence Laser — the fractional laser and RF microneedling energy is used for skin resurfacing, scar refinement, and overall skin quality within his Luminescence Laser Lift protocol.
4K Body Lift — radiofrequency energy supports skin tightening and contouring as part of the non-surgical 4K Body Lift body-sculpting protocol.
RF Microneedling Resurfacing — controlled fractional RF stimulates collagen for pores, texture, and scarring, complementing his FSX Laser skin resurfacing and skin tightening treatments.
Lecture #2: Comparison of RF Devices
Dr Sin Yong's "Comparison of RF Devices" lecture projected on the main and side screens.
In the comparison segment, Dr Sin Yong walked the audience through the technical differences between RF microneedling systems — covering needle scanning resolution, independent control over each needle, the reduced risk of stamp-pattern marks and heat overlap, and the lower chance of electrical arcing on bony areas. The session drew strong engagement from the international audience of physicians.

Representing Singapore on a global speaking faculty, Dr Sin Yong shared how device selection translates into real clinical outcomes — emphasising patient-specific protocol design over a one-size-fits-all approach to energy-based treatment.
The Award Ceremony
At the close of the summit, CLASSYS honoured its international Key Opinion Leaders with formal awards on the main stage. Dr Sin Yong received his award — presented by CLASSYS CEO Mr Baek Seung-han himself — in recognition of his clinical contributions and international advocacy for CLASSYS technologies.

CLASSYS — A Long-Standing Partnership
Dr Sin Yong has been a CLASSYS Global Key Opinion Leader for several years, and the technologies he presented in Seoul — including Secret Duo — are part of his clinical toolkit at his aesthetic practice on Orchard Road, Singapore. His work with CLASSYS platforms forms a core part of his laser resurfacing, body contouring, and skin tightening protocols.
Being invited to speak at the CLASSYS Global Customer Summit reflects the trust CLASSYS places in Dr Sin Yong's clinical outcomes, patient communication approach, and contribution to advancing aesthetic medicine education worldwide.
"To present in Seoul, at the home of CLASSYS, and to represent Singapore on a global stage — it is a real privilege. The conversations we have here ultimately raise the standard of care for patients everywhere."
