Acne scars are not all the same — boxcar, rolling, ice-pick and pigmented marks each respond to different treatments. Dr Sin Yong matches the method to the scar, combining subcision, resurfacing lasers, RF microneedling and collagen stimulation to smooth and refine acne-scarred skin.
No single treatment corrects every acne scar. Dr Sin Yong draws on a full toolkit, layering methods for a strong result across mixed scar types.

A multi-dimensional protocol that addresses acne scars at different depths in one coordinated plan — combining resurfacing, remodelling and collagen stimulation for complex, mixed scarring.

A precision resurfacing laser that refines the skin surface, softening shallow boxcar and rolling scars and improving overall texture and tone.

A technique that releases the fibrous bands tethering rolling scars to deeper tissue, allowing the depressed skin to lift and the surface to smooth.

A focal chemical application applied precisely into deep, narrow ice-pick scars to stimulate remodelling and gradually raise the scar base.

Radiofrequency energy delivered at controlled depth to remodel scar tissue and stimulate new collagen — well suited to rolling and boxcar scars with minimal surface disruption.

A collagen-stimulating injectable used to restore lost volume beneath atrophic scars, supporting the skin from below for a smoother surface over time.
Acne scars form when inflammation from acne damages the skin's collagen. The type of scar left behind depends on how that damage healed. Pitted, depressed scars — the atrophic scars most people mean by acne scarring — divide into ice-pick scars, boxcar scars and rolling scars, each with a different shape and depth. Flat brown or red pimple marks left after a breakout are pigment rather than true scars, and raised keloid or hypertrophic scars are a separate category again.
This is why there is no single right acne scar treatment. A fractional CO2 laser that refines the surface of a boxcar scar does little for a deep ice-pick scar; subcision that releases a tethered rolling scar does nothing for pigmentation. Dr Sin Yong assesses your exact mix of scar types first, then plans acne scar removal around them — which is what makes the outcome reliable rather than hit-or-miss.
Most people who seek acne scar treatment in Singapore have more than one type of scar at once, along with some pigmentation and enlarged pores. A combination plan addresses each of these on its own terms.
Dr Sin Yong draws on a full toolkit of acne scar treatments. Subcision releases the fibrous bands that tether rolling scars, letting the skin lift from below. RF microneedling delivers radiofrequency energy at a controlled depth to remodel scar tissue and stimulate new collagen, well suited to boxcar and rolling scars. Fractional CO2 laser resurfacing refines the skin surface and softens scar edges, improving overall texture and tone.
For deep, narrow ice-pick scars, TCA CROSS applies a focal treatment directly into the scar to rebuild it from within. Where atrophic scars have lost underlying volume, collagen-stimulating injectables support the skin from beneath so the surface sits smoother. These methods are frequently layered — for example subcision followed by resurfacing — because combining approaches treats mixed scarring more completely than any laser alone.
Acne scar treatment is planned as a series. Collagen remodelling happens gradually over weeks, so improvement builds across several sessions rather than appearing after one. Pigmented acne marks, if present, are treated separately with pigment-focused lasers rather than resurfacing.
Most acne scars can be significantly improved rather than erased completely. Realistic goals are smoother texture, shallower scars and a more even surface — a meaningful visible difference over a course of treatment. Downtime depends on the method: resurfacing lasers and some microneedling involve a short recovery with redness, while subcision and injectable treatments have less surface disruption.
Timing matters too. Active, inflamed acne is generally brought under control before scar treatment begins, so that new scars do not form as old ones are treated. Dr Sin Yong will advise on the right sequence and on how many sessions your scar pattern is likely to need.
The same tools that remodel acne scars also treat other kinds of scarring. Stretch marks are a true form of scarring: when skin stretches rapidly in pregnancy, growth spurts or weight change, the dermis tears and heals as fine linear streaks. Because they are dermal scars, they respond to the collagen-remodelling lasers, subcision and microneedling used for acne scars, softening their texture and helping them blend with surrounding skin. Surgical scars, injury scars and post-inflammatory marks can be improved on the same principles.
Cellulite is a related textural concern that patients often ask about at the same time. It is not scarring — it comes from fibrous bands and fat beneath the skin rather than a healed wound — but the dimpled surface can be smoothed with radiofrequency and firming, and Dr Sin Yong can advise on it during the same consultation.
Acne scars fall into distinct types, each with its own shape and its own most suitable treatment. Tap a scar type to see how it looks and how Dr Sin Yong approaches it.
Acne scar treatment in Singapore works well when the method is matched to the scar. Dr Sin Yong treats pitted acne scars including ice-pick, boxcar and rolling scars, as well as flat pigmented acne marks, drawing on subcision, RF microneedling, fractional CO2 laser resurfacing, TCA CROSS and collagen stimulation. Because most people have a mix of scar types, acne scar removal is planned as a combination rather than a single laser, targeting each scar at the right depth for smoother, more even skin over a series of sessions.
For deep, ice-pick and boxcar scars, treatment depth is decisive. The S3 Laser is the clinic's primary choice for these scars because it runs on updated DEKA laser technology from Italy and reaches roughly three times deeper into the dermis than conventional fractional CO2 lasers or RF microneedling — a key reason it produces significant improvement on scarring that shallower devices cannot reach. Its concentrated beam of energy drives deep dermal restoration where shallower devices cannot reach, making it effective across deep and severe scars as well as ice-pick, boxcar and other atrophic acne scars. A pioneer in scar aesthetics, Medical Director Dr Sin Yong combines the S3 Laser — powered by DEKA technology — with his own 4D Scar Reconstruction protocol and methods such as subcision, TCA CROSS and collagen stimulation, achieving significant change on scars that shallower single-device treatments cannot.
Raised keloid and hypertrophic scars differ from the pitted scars most people mean by 'acne scars' — they sit above the skin and are managed differently, often with intralesional injections and energy-based devices rather than resurfacing. At consultation Dr Sin Yong distinguishes raised scars from pitted ones and plans accordingly, since treating them the same way can worsen a raised scar.
Asian and darker skin tones carry a higher risk of post-inflammatory pigmentation, so device choice and settings matter. Dr Sin Yong holds an MSc in Practical Dermatology (Cardiff) and calibrates conservatively for pigment-prone skin, often favouring subcision and radiofrequency microneedling, which treat the scar with lower surface risk. Sun protection between sessions is part of the plan.
It can be, but timing matters. Active acne is usually brought under control first, and younger skin is assessed individually. Dr Sin Yong reviews each case at consultation and, for younger patients, discusses the plan with a parent or guardian present.
Because scars are structural, improvements are generally lasting, but skin quality benefits from ongoing care — sun protection, a suitable routine, and keeping any active acne controlled so new scarring is less likely. Dr Sin Yong advises on maintenance at review.
Acne scar correction depends on accurate diagnosis of the scar type — boxcar, rolling, ice-pick or a mix — because each responds to different techniques. Dr Sin Yong is an aesthetic physician who holds an MSc in Practical Dermatology (University of Cardiff) and combines subcision, fractional laser and radiofrequency microneedling, matching the method to each scar type rather than applying a single treatment. Scars are assessed individually at consultation on Orchard Road, Singapore.
Yes. Stretch marks are a form of dermal scarring — the deeper skin tears as it stretches during pregnancy, growth or weight change and heals as fine streaks. They respond to the same collagen-remodelling lasers, subcision and microneedling used for acne scars, refining their texture over a course of sessions. Newer marks tend to improve more readily than older, silvery ones.
Yes. Surgical scars, injury scars and post-inflammatory marks can be improved using the same resurfacing, subcision and collagen-stimulation principles, matched to the scar’s depth and texture. Cellulite, a related textural concern rather than a scar, can also be discussed at the same consultation. Dr Sin Yong will assess which approach suits each mark.
There is no single right treatment — the right choice depends on your scar type. Ice-pick scars, boxcar scars, rolling scars and pigmented marks each respond to different methods. Dr Sin Yong assesses your scar pattern first, then matches and combines treatments accordingly.
Most acne scars can be significantly improved rather than erased entirely. Realistic goals are smoother texture and a more even surface. Dr Sin Yong discusses expected improvement honestly, since results depend on scar depth, type and skin response.
Scar treatment is usually a series rather than a single visit, because collagen remodelling happens gradually. The number depends on scar severity and the methods used, and is set out in a personalised plan after assessment.
It varies by method. Resurfacing lasers and some microneedling involve a short recovery with redness, while other treatments have minimal downtime. Dr Sin Yong explains what to expect for your specific plan.
Generally yes. Active, inflamed acne is usually settled before scar treatment begins, so that new scarring does not form. Dr Sin Yong will advise on timing at consultation.
Yes — combining methods is often the most effective approach for mixed scarring, for example subcision to release rolling scars alongside resurfacing for texture. This is planned around your individual scar pattern.
The cost of acne scar treatment and removal depends on your scar types, how severe they are, and how many sessions and methods are needed. Because plans are personalised to your scar pattern rather than sold as a fixed package, Dr Sin Yong gives a clear quote after assessing your skin at consultation.
There is no single right treatment for pitted or depressed acne scars — it depends whether they are ice-pick, boxcar or rolling scars. Deep ice-pick scars often need TCA CROSS, boxcar scars respond to resurfacing and RF microneedling, and rolling scars usually need subcision. Most people benefit from a combination.
Both are effective, but for different scars. RF microneedling remodels scar tissue at depth with minimal surface disruption, while fractional CO2 laser resurfaces and refines the surface. Dr Sin Yong may use either or both depending on your scar type and skin, rather than relying on one device for everything.
Yes. Flat brown or red marks left after acne are pigmentation rather than true scars, and they are addressed with pigment-focused and toning lasers rather than resurfacing. These are often treated alongside a scar plan so the overall result looks clearer and more even.
