In October 2025, Dr Sin Yong co-presented with Dr Davin Lim at the DEKA Tetra Pro S3 Resurfacing Training held at Bio Aesthetic Laser Clinic, Singapore — sharing his protocol for acne scar resurfacing with the DEKA Tetra Pro and, in an uncommonly candid clinical gesture, volunteering himself as the live demonstration patient for Dr Davin Lim to treat.
An International Authority Consensus — Two KOLs, One Stage
The training was designed as a genuine peer-to-peer clinical education event: two of Singapore’s most internationally recognised aesthetic physicians presenting side by side on the DEKA Tetra Pro platform. Dr Sin Yong presented his S3 Resurfacing protocol for acne scars, while Dr Davin Lim — Founder of 101.skin Sydney, internationally recognised laser authority, and one of the most published aesthetic physicians in the Asia-Pacific region — performed the live Tetra Pro treatment on Dr Sin Yong himself, with the full attending physician audience observing.
The combination of Dr Sin Yong’s acne scar resurfacing protocol expertise and Dr Davin Lim’s internationally validated laser technique created an unusually high-calibre educational environment for the attending Singapore physicians — one that blended protocol instruction with live, real-patient clinical execution in the same session.

The Protocol: S3 Resurfacing for Acne Scars
Dr Sin Yong presented his clinical protocol for acne scar resurfacing using the DEKA Tetra Pro — a CO₂ fractional laser platform with SmartXide technology that enables precise control of laser spot geometry, depth, density and pulse stacking. The S3 Resurfacing approach (Stack, Scan, Sculpt) represents Dr Sin Yong’s systematic framework for addressing the three architectural challenges of acne scarring:
- Stack — managing the depth and thermal effect of each ablative pulse to target the base of deep box scars and rolling scars without excessive adjacent tissue injury
- Scan — optimising scan pattern, density and spacing to balance resurfacing coverage against healing time and risk of post-inflammatory hyperpigmentation, particularly for Asian skin types
- Sculpt — using the Tetra Pro’s spot geometry flexibility to reshape scar topography through selective ablation — deepening the floor of raised scars, releasing tethered rolling scars, and blending scar edges into surrounding skin
“Acne scar resurfacing with a CO₂ fractional laser is one of the most technically demanding procedures in aesthetic medicine. The Tetra Pro gives us the precision to treat heterogeneous scar morphology — ice picks, box scars, and rolling scars — within the same session, with a single platform, and with a level of parameter control that older CO₂ lasers simply couldn’t offer.”
Dr Sin Yong as Patient — A Live Demonstration on Acne Scars
In what was perhaps the most clinically striking element of the day, Dr Sin Yong volunteered himself as the live demonstration patient — allowing Dr Davin Lim to perform the Tetra Pro S3 Resurfacing treatment on his own acne scars in front of the full attending physician audience.
The decision to be treated is a direct expression of clinical confidence: Dr Sin Yong has lived with the acne scarring he treats patients for, and his willingness to undergo the procedure under the hands of a peer — in front of an audience of fellow physicians — carries a meaning that no formal lecture or case study can replicate. It also gave the attending physicians a uniquely transparent view of the treatment experience from the patient’s perspective.

“There is something powerful about being on the table yourself. I know exactly what the heat feels like, what the recovery involves, and what realistic improvement looks like over six to twelve months. That firsthand understanding changes how I counsel patients — and it gives me absolute confidence when I tell them the procedure is worth it.”
Dr Davin Lim — International Authority in Laser Aesthetics

Dr Davin Lim is the founder and lead physician of 101.skin in Sydney — one of the most internationally recognised aesthetic medicine practices in the Asia-Pacific. He is widely regarded as one of the foremost laser authorities in the region, with an extensive publication record in peer-reviewed dermatology and laser medicine literature and a reputation for evidence-based, technically precise practice. His endorsement and collaboration with Dr Sin Yong on the DEKA platform represents a meaningful peer-level validation of the clinical approaches they share.
For the attending Singapore physician audience, having both physicians present in the same room — with Dr Davin Lim performing the treatment and Dr Sin Yong receiving it — created an educational experience that was simultaneously a masterclass in laser technique, a protocol education session, and a rare moment of clinical transparency between two senior peers.
“Working alongside Davin in this format — where he treats me and I’ve shared my own protocol with the room — is how clinical knowledge is supposed to transfer. Not from a textbook, not from a slide deck: from one physician to another, at the chairside, with a real patient. And in this case, I was the patient.”
DEKA — A Partnership in CO₂ Laser Excellence
Dr Sin Yong holds International Key Opinion Leader status with DEKA, the Italian laser manufacturer behind the Tetra Pro platform. DEKA’s SmartXide CO₂ fractional technology is integrated into his acne scar reconstruction and skin resurfacing protocols at his Orchard Road practice in Singapore, and forms a central element of his approach to scar remodelling, textural correction, and the treatment of post-inflammatory skin changes in Asian skin types.
His selection as a co-trainer for the Singapore DEKA physician education event — alongside Dr Davin Lim — reflects the depth of that partnership and the clinical credibility that both physicians bring to the DEKA platform in the Singapore market.
