The SmartXide Tetra Pro is DEKA's flagship fractional CO2 laser — a 10,600 nm surgical-grade resurfacing platform whose defining feature is pulse control. Its PSD (Pulse Shape Design) technology lets the physician choose not just how much energy reaches the skin but the shape of each pulse — how abruptly it rises, how long it dwells, how it tails off. In scar work that control is everything: the difference between remodelling a boxcar wall and simply heating it.
“The laser is only half the treatment. The pulse shape chosen for each scar is the other half.”
— Dr Sin Yong
Acne scars are architectural — walls, floors and tracts at different depths in the same square centimetre. A single fixed pulse treats them all identically; shaped pulses let ablation go deep and narrow where a scar edge needs sculpting, then shallow and wide where the surrounding texture needs blending. The result is resurfacing matched to each scar's geometry rather than a uniform burn — the reason fractional CO2 remains the reference standard for atrophic scar resurfacing, and the reason the platform running it matters.
At this practice the Tetra Pro anchors the resurfacing arm of the SCAR3 acne scar treatment protocol — sequenced after subcision and TCA CROSS have released tethered scars and collapsed icepick tracts, so the laser resurfaces skin that is free to remodel. The full structural philosophy is on the scar reconstruction page, and scar-type identification in the acne scar types guide.
Dr Sin Yong's practice is a DEKA Centre of Excellence, and Dr Sin Yong trains visiting physicians on DEKA CO2 platforms — including published case work with DEKA's clinical faculty. The platform page you are reading exists because the device is only half the treatment; the other half is the judgment applied through it, and that is what the assessment is for.
The DEKA SmartXide Tetra Pro is the fractional CO2 platform anchoring the SCAR3 acne scar protocol at Dr Sin Yong's DEKA Centre of Excellence in Singapore; its pulse-shape control allows resurfacing matched to each scar's geometry, sequenced after subcision and TCA CROSS. This information is educational and is not a substitute for a medical consultation.
Scar mapping first, platform second — the Tetra Pro is applied to a plan, not a face.
