Hands-On Physician Training
Dr. Sin Yong led hands-on training in the Tetra Pro Scar³ multi-depth resurfacing protocol — the DEKA CO2 platform application underpinning his acne scar and 4D Scar Reconstruction work.
The protocol penetrates considerably deeper than conventional fractional CO2, delivering concentrated energy for deep dermal restoration across ice-pick, boxcar and atrophic scar morphologies.
Attending physicians observed live treatment and worked through parameter selection by scar type and Fitzpatrick phototype.
