The Summit

The CLASSYS Global Customer Summit is an annual gathering of physicians and dermatologists from across the globe to Seoul — the home of CLASSYS — to share clinical protocols and device innovations.

Held under the theme "Expanding Possibilities in Medical Aesthetics," the 2025 summit featured a lecture programme, live demonstrations, and an award ceremony recognising the company's leading 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, first developed by ilooda, which is now part of CLASSYS. It combines RF microneedling, a 1540 nm non-ablative fractional laser and Smart Cure in one device. He covered how he selects and combines microneedling RF devices in clinical practice. His talk explained the decision framework he uses for different skin concerns and body zones.

How Dr Sin Yong Uses Secret Duo

In Eternity Aesthetics & Medical Surgery in Singapore, Dr Sin Yong applies the Secret Duo platform across three distinct protocols:

Luminescence Laser — the fractional laser and RF microneedling energy is used within his Luminescence Laser Lift protocol.
4K Body Lift — radiofrequency energy is used as part of the non-surgical 4K Body Lift 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
