Rolling scars treatment in Singapore:
release the tether first

Rolling scars treatment Singapore: start with the anatomy

Of the three depressed acne scar types described by Jacob and colleagues, the rolling scar is the one whose cause is not at the surface at all (Jacob 2001). When deep acne inflammation heals, scar tissue can form as a vertical cord anchoring the underside of the dermis to the tissue beneath. The skin above is intact; the broad, soft-edged dip exists because something is pulling it down from inside, the way a thread pulls an upholstery button into a cushion. That is why rolling scars look worse under angled light and when the face moves, and why they flatten when the skin beside them is stretched. Most scarred cheeks carry rolling scars alongside boxcar scars and ice-pick scars, so the acne scar treatment Singapore guide maps all three; this page is about the rolling scar alone, and the one step it needs that the others do not.

The stretch test: how a tether is found

Dr Sin Yong finds tethers by examination, not photographs, because a tether shows on stretch and animation and neither shows in a picture. The skin beside each scar is stretched between two fingers under side light. A scar that flattens or nearly disappears is being held down from below, whatever its shape. One that deepens when you smile is transmitting the pull of the muscle beneath. One that stays as a sharp pit or a flat-floored dent on stretch is a depth problem, not a tether, and goes to a different tool. The acne scar assessment page lists everything graded at that visit; what comes out of it for rolling scars is a map of which ones need release and which, being untethered and shallow, can go straight to resurfacing.

Acne rolling scar treatment: why subcision comes first

subcision, short for subcutaneous incisionless surgery, treats the cause (Orentreich 1995). Under local anaesthetic a fine needle or blunt cannula is introduced through a small puncture beside the scar and swept beneath it in a fanning pattern to divide the band; release is often felt as a give. Two things follow. The downward pull is gone, so the surface is free to sit level. And the controlled injury beneath the scar prompts a repair response, with new collagen forming where the band was. The skin is entered through a puncture rather than cut, so there are no sutures; bruising, swelling and tenderness are expected and settle. The band can partly re-form as the area heals, which is one reason subcision is planned within a staged sequence with each scar reviewed, rather than as a one-off. In Dr Sin Yong’s 4D Scar Reconstruction it is the foundation step, done before anything is placed under the scar or passed over it.

Support: when Radiesse goes under a released scar

Filler helps a rolling scar only where the tissue beneath it has thinned, and does nothing for the tether, so the order is fixed: subcision first, support second. Where a volume deficit remains after release, Radiesse, a calcium hydroxylapatite collagen-stimulating injectable, is placed into the released space to support the floor at the time of placement and to prompt collagen over the following months. Placed under an intact band, filler tends to spread around it rather than lift the scar. No filler changes scar edges, texture or an ice-pick tract, and whether a particular released scar needs support at all is decided scar by scar at review, not assumed. The pairing is set out on subcision with filler.

Resurface: Secret DUO or S3 Resurfacing Lift after release

Once the surface is free, energy can do its job. For shallow rolling scars and the texture between them Dr Sin Yong uses RF microneedling on the Secret DUO: insulated microneedles deliver bipolar radiofrequency at a set depth with the surface spared, and insulated needles are generally his choice in Fitzpatrick IV to VI skin (Syder 2023; Chandra 2024). For deeper rolling scars and steep edges he uses the S3 Resurfacing Lift, fractional CO₂ with point shots into pits and then fractional passes. Superficial textural scarring between the scars suits FSX Laser. Depth decides between the two lasers: FSX Laser for superficial scars, with a shorter recovery than S3, and the S3 Resurfacing Lift for deep ice-pick and boxcar scars. Whether release and resurfacing happen at one visit or are staged depends on the scars, the skin type and how bruising is expected to behave; in Fitzpatrick III to V skin, staging is often the more conservative choice.

Why energy alone fails, and when to stop

Lasers and radiofrequency act on the dermis from above; the band holding a rolling scar sits below, deeper than resurfacing energy is meant to reach. That is why scar journeys so often plateau: the surface scars improve and the few that were tethered stay put until the tether itself is addressed. More energy is not the answer, and in Fitzpatrick III to V skin inflammation has its own cost in post-inflammatory pigment. Some rolling scars should wait: active acne is controlled first, recent isotretinoin is reviewed, blood thinners and bleeding tendency matter for subcision, and a keloid tendency is weighed. Isolated scars too deep or wide for these methods are referred to a plastic surgery specialist for a punch technique. Risks of the sequence include bruising, lumps, infection, pigment change and a scar that responds less than hoped; no outcome is promised. The subcision vs laser comparison goes deeper, and every acne and scar guide on this site is indexed in one place.

“You can resurface a tethered scar indefinitely. The tether keeps pulling it down.”
