S3 Resurfacing Lift is Dr Sin Yong's multi-depth laser resurfacing protocol for acne scars on the DEKA Tetra Pro CO₂ platform. The depth and density of the fractional CO₂ passes are varied across the face according to a scar map, so ice pick, boxcar and rolling scars each receive the energy they need. It is the protocol he uses for scars that did not fully respond to earlier CO₂ laser or RF microneedling.
The S3 Resurfacing Lift appears across the acne-scar cluster because it is the protocol most acne-scar plans end with, after the scar map has decided what else is needed first.
I do not resurface a tethered scar; I release it first, because a laser cannot cut a cord.— Dr Sin Yong
If you are starting from a diagnosis rather than a device, the acne scar assessment page describes how the scar map is built at the first visit.
Several scar treatments on this site share words with the S3 Resurfacing Lift. The differences are in depth, mechanism and sequence.
The short version: depth decides. Superficial scars go to FSX, deep scars to S3, tethered scars to subcision first, and ice-pick scars to TCA CROSS, with the laser following.
The protocol is chosen from the scar map, not from the diagnosis of acne scarring alone. These are the questions Dr Sin Yong answers before it is planned.
What the protocol cannot do is also stated plainly: it does not remove a scar, it remodels the floor and edges of it, and it does not replace the release of a tethered scar. Expectations are set at consultation and reviewed after each stage.
S3 Resurfacing Lift is the protocol Dr Sin Yong uses most for acne scars, one of the six concerns he treats day in, day out. Full page: S3 Resurfacing Lift; compared with RF microneedling on S3 Resurfacing Lift vs Secret RF.
Yes: fractional CO₂ on the DEKA Tetra Pro, run as a multi-depth sequence set by the scar map rather than as one setting.
No. Tethered rolling scars are released by subcision first, then resurfaced.
