Acne Scars, Active Acne and Dark Marks: What Are You Treating?

Not every post-acne mark needs the same treatment. Some concerns are active breakouts. Others are flat colour changes. True acne scars usually involve a change in skin texture, such as depressions, pits, uneven skin or raised scar tissue.

Active acne

Active acne refers to ongoing breakouts such as whiteheads, blackheads, inflamed pimples, pustules, nodules or cysts. If breakouts are still frequent or inflamed, acne control may need to come first. Treating the scars too early may lead to more irritation, new marks or further scarring.

Acne scars

Acne scars are textural changes left after deeper inflammation has affected the skin’s healing process. They may look like ice pick scars, boxcar scars, rolling scars, enlarged pores with uneven texture, or raised keloid-like scars. These usually do not fade with brightening skincare alone because the issue is structural, not just colour.

Dark marks and red marks after acne

Flat brown marks are usually post-inflammatory hyperpigmentation (PIH), while flat pink, red or purplish marks may be post-inflammatory erythema (PIE). These marks can happen with or without true scarring. A doctor-led assessment helps separate colour concerns from pitted scars so the treatment plan can target the right problem.

Concern What It Looks Like Main Treatment Focus
Active acne New or ongoing inflamed spots, pustules, nodules or cysts Control inflammation and reduce new breakouts first
PIH Flat brown or grey-brown marks after acne Pigment control, sun protection and suitable pigment treatments
PIE Flat pink, red or purplish marks after acne Redness and vascular-focused treatment planning where suitable
Acne scars Pits, depressions, tethering, uneven texture or raised scar tissue Scar remodelling, resurfacing, release, collagen support or combination treatment

 

PIH vs PIE: Why Brown Marks and Red Marks Need Different Treatment Plans

Post-acne marks are common in Singapore, especially for patients with Asian skin tones that may be more prone to pigmentation after inflammation. PIH and PIE can look similar from a distance, but they behave differently and may need different treatment priorities.

Post-inflammatory hyperpigmentation (PIH)

PIH is a flat brown, grey-brown or darker mark that appears after acne inflammation. It happens when the skin produces extra pigment while healing. PIH can become more noticeable after sun exposure, picking, harsh exfoliation or aggressive treatment settings.

Treatment may include daily sunscreen, pigment-regulating skincare, suitable chemical peels, Pico laser, or other pigment-focused options after a skin assessment. For deeper skin tones, the treatment plan should be cautious to minimise the risk of further pigmentation.

Post-inflammatory erythema (PIE)

PIE is a flat red, pink or purplish mark caused by lingering inflammation and visible blood vessels after acne. It is not the same as brown pigmentation, so brightening creams alone may not fully address it.

Depending on the skin and severity, redness-focused lasers or light-based treatments may be discussed. The doctor will also check whether there is active acne, sensitivity, rosacea-like redness or a recent procedure history before recommending treatment.

When PIH, PIE and scars happen together

Many patients have more than one concern at the same time. A pitted scar may sit beside brown pigmentation, or a rolling scar may also have redness around it. In these cases, treatment may be staged so colour, inflammation and texture are handled in the safest order. Results may vary depending on scar depth, skin type, aftercare and the number of sessions needed.

Acne scars form when deeper inflammation affects the dermis and disrupts the skin’s normal healing process. When collagen is lost or repair tissue develops unevenly, the skin may heal with depressed, tethered, raised or uneven scars.

The Science of Acne Scars: Understanding Dermal Remodelling

The scar pattern depends on the depth and duration of inflammation, acne severity, skin type and individual healing response. This is why acne scar treatment in Singapore should begin with a clinical assessment rather than a single standard procedure.

Common mechanisms include:

  • Collagen loss, which can cause atrophic or sunken scars.
  • Fibrous tethering, where bands pull the skin down and create rolling texture.
  • Excess repair tissue, which can lead to raised hypertrophic or keloid-like scars.

The Clinical Pathogenesis of Acne Scarring

Acne scarring develops when inflammation from acne extends deeper into the skin and affects normal tissue repair. As the skin heals, collagen may be lost, produced unevenly or replaced with fibrous tissue.

This can lead to different scar patterns, including ice pick scars, boxcar scars, rolling scars or raised scars. Because each scar type forms differently, the most suitable acne scar treatment plan may involve a combination of resurfacing, collagen stimulation, scar release or injectable support.

A clinical assessment helps identify the scar type, depth, skin condition and whether active acne or pigmentation should be treated first.

Types of Acne Scars: A Clinical Classification

Effective acne scar treatment begins with an accurate diagnosis. Most patients present with a polymorphic mix of scar types, each requiring a specific medical modality for optimal restoration.

Scar Type Clinical Appearance Primary treatment(s) Typical Sessions
Ice-pick Scars Deep, narrow pits resembling small puncture marks in the skin surface TCA CROSS; punch excision for wider variants 2–4 sessions, 4–6 weeks apart
Boxcar Scars Broad, depressed areas with sharply defined vertical edges Fractional CO2 laser; RF microneedling 3–5 sessions
Rolling Scars Wavy or undulating texture caused by deep fibrous bands tethering the skin downward Subcision + dermal fillers or Rejuran S 2–4 sessions, repeated based on clinical response
Hypertrophic scars Raised, thickened tissue forming above the skin surface Steroid injections; vascular lasers Variable

Smoothen Scars And Textures With Glowwis Acne Scar Treatment Options

At Glowwis, our board-certified-aesthetic doctor, Dr Sam, specialises in tailored Acne scar treatments designed to enhance the appearance of scars. After a thorough analysis of your skin’s condition, he will determine the most suitable approach for you.

PICO LASER

PICO Laser delivers ultrashort pulses of laser energy in the picosecond range and helps to break down scar tissue, stimulate collagen production, and promote skin regeneration, resulting in improved texture and appearance with minimal discomfort and downtime. The treatment is performed using Dr. Sam’s techniques which have yielded desirable results.

GOLD PLATED MICRO NEEDLE RF

Gold Plated Micro Needle RF combines the technology of micro-needling and radiofrequency to encourages collagen synthesis, improving acne scars, and enhancing product absorption. The treatment helps to create micro-injuries that reach the dermal layers of the skin. Because of this process, the skin will produce new skin tissues to smoothen the appearance of acne scars.

Learn More

JUVE BOOSTER

Juve Booster contains Hyaluronic Acid (HA) and Poly D-Lactic Acid (PDLA). By injecting the treatment into the skin, the HA molecules provide the skin with moisture, while ultrafine PDLA activates fibroblasts which encourages the production of collagen. This process aids in creating a smoother and even texture by filling in the depressed areas that occur due to acne scars.

Learn More

DERMAL FILLER

Dermal fillers help to encourage the production of collagen. This process aids in promoting a smoother skin surface which diminishes the appearance of acne scars. The treatment will only take 15 to 30 minutes, depending on the number of fillers.

Learn More

SUBCISION

Subcisions release fibrous bands that tether scars, which stimulates collagen production and creates a smoother skin surface. During the subcision procedure, Dr. Sam uses a needle or a blade to carefully break the fibrous bands or connective tissue that anchor the scar to the underlying tissue. By releasing these tethers, the depressed scar is allowed to rise, resulting in an improvement in the overall appearance of the skin.

Learn More

FRACTIONAL CO2 LASER

Using carbon dioxide to create a laser beam, CO2 Laser helps to remove the damaged skin layers. Doing so helps to stimulate collagen production which helps with smoothening scars and reducing hyperpigmentation. For acne scars, Dr. Sam incorporates this treatment to precisely remove the damaged outer layers of the skin, allowing newer and healthier skin to replace it.

Microneedling vs RF Microneedling: What Is the Difference?

Microneedling and RF microneedling both use fine needles to create controlled micro-injuries in the skin. The difference is that RF microneedling also delivers radiofrequency energy into the dermis, adding a heat-based collagen-remodelling effect.

 

Feature Traditional Microneedling RF Microneedling
Main action Creates controlled microchannels to stimulate wound healing and collagen response. Creates microchannels and delivers radiofrequency heat at selected depths.
Common scar focus Mild texture changes, early scars, general collagen induction and selected superficial concerns. Rolling scars, boxcar scars, enlarged pores and mixed texture concerns where deeper remodelling is needed.
Heat energy No RF heat energy is delivered. RF heat is delivered through the needle tips or insulated needles, depending on the device.
Downtime Usually mild redness and sensitivity, depending on depth and passes. May involve redness, swelling, pinpoint marks or tenderness for a few days, depending on settings.
Skin tone considerations Still requires careful depth and aftercare to reduce irritation and PIH risk. May be considered where deeper remodelling is desired while limiting surface ablation, but settings must still be chosen carefully for Asian skin.

 

Which one is better for acne scars?

There is no single “better” option for every patient. Traditional microneedling may suit milder texture concerns, while RF microneedling may be discussed for deeper collagen remodelling. If active moderate-to-severe acne, infection, recent isotretinoin use, keloid tendency or significant sensitivity is present, treatment may need to be delayed or modified after medical assessment.

Rejuran S, Polynucleotide and PDRN for Acne Scars

Rejuran S is commonly discussed in Singapore as a polynucleotide-based injectable used in selected acne scar plans. Polynucleotides (often shortened to PN or PDRN in clinic discussions) are used to support skin repair and dermal remodelling. Rejuran S is not a laser and is not the same as a dermal filler that gives instant lifting volume.

How Rejuran S may fit into acne scar treatment

For suitable patients, Rejuran S may be considered as an adjunct for depressed or atrophic acne scars, especially where the treatment goal includes skin repair support and gradual texture improvement. It is often discussed alongside subcision, fractional CO2 laser, RF microneedling or TCA CROSS rather than as a one-size-fits-all standalone solution.

What to expect

Treatment usually involves small injections into selected scar areas. Temporary redness, swelling, bruising, tenderness, needle marks or small bumps may occur after treatment. Visible changes are gradual and usually require a series of sessions. Results may vary depending on scar depth, skin quality, treatment spacing and aftercare.

Who may not be suitable

Rejuran S may not be the first choice for active inflamed acne, infection in the treatment area, raised keloid-like scars, certain medical conditions, pregnancy, breastfeeding, medication-related bleeding risk or patients expecting immediate dramatic filling. Suitability should be assessed by the doctor before treatment.

Before and After Expectations: What Timeline Is Realistic?

Acne scar treatment is usually a gradual process. Most treatments aim to improve the appearance of scars, not erase every mark or create perfectly smooth skin. The timeline depends on scar type, severity, skin tone, treatment modality, healing response and aftercare. Results may vary.

 

Stage What Patients May Notice
Before treatment The doctor assesses active acne, scar type, pigmentation, redness, skin sensitivity, keloid tendency, medications and downtime preferences. Baseline photos may be taken.
First few days Redness, swelling, tenderness, peeling, scabbing, bruising or small injection bumps may occur, depending on the modality. Follow the clinic’s aftercare instructions closely.
Weeks 2 to 6 Surface recovery usually improves. Pigmentation or redness may still be visible, especially in Asian skin or after stronger resurfacing treatments.
Months 2 to 3 Early collagen remodelling may become more noticeable. Some scars may soften, look shallower or appear less shadowed.
Months 3 to 6 and beyond More meaningful texture changes often require a series of sessions. Improvement can continue gradually as collagen remodels, but complete scar removal should not be expected.

 

How many sessions are usually needed?

Mild texture changes may need fewer sessions, while mixed rolling, boxcar and ice pick scars often need a staged plan. Combination therapy may involve treatments spaced several weeks apart to allow healing between sessions. The exact number of sessions should be advised only after clinical assessment.

Acne Scar Treatment Cost in Singapore: Indicative Price Guide

The cost of acne scar treatment in Singapore depends on the scar type, treatment area, severity, number of sessions, technology used, injectable volume, doctor assessment, aftercare and whether combination therapy is needed.

The figures below are indicative Singapore market ranges compiled from publicly available clinic pricing and competitor cost guides. They are not final Glowwis fees. A personalised quote should be given only after a doctor-led skin assessment.

 

Treatment Modality Common Use Case Indicative Singapore Market Range
Pico laser / pigment-focused laser Selected post-acne marks, PIH, mild texture concerns or adjunctive scar plans Approx. S$450 to S$580+ per session, depending on protocol and clinic
Fractional CO2 laser Atrophic texture, boxcar scars, rolling scars and resurfacing support Approx. S$398 to S$1,500+ per session; some clinics list up to S$3,000 for larger or specialist cases
RF microneedling Rolling scars, boxcar scars, enlarged pores and deeper collagen remodelling with less surface ablation than CO2 laser Approx. S$200 to S$1,500 per session, depending on device, tips and treatment area
Subcision Tethered rolling scars and selected depressed scars Approx. S$350 to S$800 per session
TCA CROSS Deep, narrow ice pick scars or selected small boxcar scars Approx. S$250 to S$600 per session
Rejuran S / polynucleotide / PDRN scar injectable Selected depressed scars, dermal support and combination scar remodelling plans Approx. S$350 to S$800 per session or around S$500 to S$600 per syringe, depending on product and volume
Dermal fillers Selected depressed scars needing temporary volume support Approx. S$600 to S$1,200 per syringe
Chemical peels / pigment peels Superficial pigmentation, skin renewal and adjunctive PIH care Approx. S$150 to S$500 per session

 

Why combination plans cost more?

Mixed acne scars may need more than one modality because each treatment addresses a different layer or scar pattern. For example, subcision may release tethered rolling scars, while fractional CO2 laser or RF microneedling may support texture remodelling. TCA CROSS may be added for selected ice pick scars, while pigment or redness treatments may be used for PIH or PIE.

Clinical Strategies for Acne Scar Restoration in Singapore

Effective acne scar treatment in Singapore requires a structured, multimodal approach. Structural scar damage — particularly atrophic scarring — cannot be meaningfully addressed by topical skincare alone, regardless of formulation or concentration. Over-the-counter options do not penetrate to the dermal depth at which fibrous tethering and collagen loss occur.

A clinically grounded programme proceeds across three stages:

Stage 1 — Medical-grade skin preparation

Clinical-strength retinoids, ascorbic acid derivatives, and targeted topical agents are used in the weeks prior to procedural intervention. These prime the dermis, improve cellular turnover, and help sustain the results of deeper treatments between sessions. This preparatory phase is often overlooked by patients who seek standalone procedures, but it is a meaningful component of a comprehensive programme.

Stage 2 — Procedural dermal remodelling

Structural correction of acne scars requires direct intervention at the level of the dermis. Depending on scar classification, the appropriate combination of procedures may include:

  • Subcision for acne scars — to release fibrous tethering beneath rolling scars
  • Fractional CO2 laser — to stimulate collagen synthesis and remodel scar edges (5–7 days social downtime per session)
  • TCA CROSS — targeted reconstruction of ice-pick and narrow boxcar scars
  • RF microneedling — broad collagen induction with 2–4 days social downtime
  • Pico laser — post-inflammatory pigmentation overlying atrophic scars (1–3 days downtime)

Published studies report visible improvement in acne scars after procedural treatments, though results vary by scar type, skin type, severity, and treatment plan.

Stage 3 — Maintenance and long-term skin health

Collagen remodelling continues for up to six months following each procedural session. A maintenance protocol — typically involving periodic low-intensity treatments and medical-grade topical care — supports progressive improvements and helps preserve results over time.

A comprehensive dermal assessment by an SMC-registered doctor is essential before any treatment commences. The assessment identifies your specific scar polymorphic profile, skin type, and any contraindications that may affect the choice or sequence of clinical procedures.

Recovery and Aftercare After Acne Scar Treatment

Recovery varies depending on the treatment. Pico laser or lighter procedures may have minimal downtime, while fractional CO2 laser, subcision, TCA CROSS or combination treatments may involve several days of visible healing. Your clinic will provide specific aftercare based on the modality used.

Immediately after treatment

  • Keep the treated area clean and avoid touching it unnecessarily.
  • Use only the soothing products or recovery creams recommended by the clinic.
  • Do not pick, scratch, peel or remove scabs, as this can increase the risk of pigmentation and scarring.
  • Avoid make-up until the clinic advises that the skin barrier has recovered enough.

First 48 to 72 hours

  • Avoid direct sun exposure, tanning, sauna, steam rooms, hot yoga and intense exercise unless your doctor advises otherwise.
  • Use a gentle cleanser and moisturiser, and avoid scrubs, exfoliating acids, retinoids, strong vitamin C, benzoyl peroxide or other actives unless specifically instructed.
  • Avoid alcohol-based toners, harsh masks and non-prescribed acne spot treatments on treated areas.
  • For subcision or injectables, avoid pressing or massaging the area unless your doctor has specifically told you to do so.

First 1 to 2 weeks

  • Apply broad-spectrum sunscreen daily once your doctor says it is suitable for your skin stage.
  • Use shade, caps or umbrellas when outdoors, especially in Singapore’s strong UV environment.
  • Restart active skincare only when the skin has healed and your doctor has cleared it.
  • Contact the clinic if you notice worsening pain, pus, spreading redness, blistering, fever, unusual swelling or sudden darkening of the treated area.

Between sessions

Continue acne control and sun protection between sessions. New breakouts can create new marks or scars, while unprotected UV exposure can worsen PIH. Good aftercare helps reduce avoidable complications and supports a steadier treatment response. Results may vary.

Risks, Side Effects and Who May Not Be Suitable

Acne scar treatments are medical aesthetic procedures and should be planned after a proper skin assessment. Side effects and risks depend on the treatment used, device settings, injection technique, skin tone, scar type, medication history and aftercare.

A consultation helps Dr Sam assess your skin, explain suitable options, discuss possible risks and recommend a treatment plan based on your scar type, skin tone, downtime preference and medical history.

Common temporary effects

Depending on the procedure, patients may experience redness, swelling, warmth, tenderness, dryness, peeling, pinpoint bleeding, crusting, scabbing, bruising, small injection bumps or temporary darkening of treated marks. Your doctor will explain the expected recovery window before treatment.

Possible Risks and Suitability Considerations

Less common risks may include post-inflammatory hyperpigmentation, prolonged redness, infection, acne flare, delayed healing, uneven texture, scarring, keloid worsening, allergic reactions or injectable-related complications.

Treatment may need to be delayed or adjusted if you have:

  • Active infection
  • Open wounds
  • Cold sores
  • Inflamed acne
  • Recent sunburn
  • Heavy tanning
  • A history of keloids
  • Recent isotretinoin use
  • Pregnancy or breastfeeding
  • Blood-thinning medication use
  • Medical conditions that may affect healing

General Habits To Prevent Acne Scars

EARLY TREATMENT

Addressing the early signs of acne helps to reduce inflammation and minimise the risk of scarring.

AVOID HARSH SCRUBS

Steer clear of harsh exfoliating scrubs, as they can exacerbate inflammation and potentially lead to scarring.

SUN PROTECTION

UV rays are one of the common causes of pigmentation that prevents scars from healing. Using sunscreen with SPF30 can provide significant protection to your skin.

STAY HYDRATED

Drink plenty of water to keep your skin hydrated and support its natural healing processes.

BALANCED DIET

Consuming a diet rich and balanced with nutrients, vitamins, and minerals helps with skin healing and maintain overall health.

AVOID OVEREXPOSURE TO THE SUN

Overexposure to sun rays can prevent your skin from healing and darken hyperpigmentation. It is best to apply sunscreen, layer on protective clothing, and put on shades if you’re outdoors.

Frequently Asked Questions (FAQs)

How much does acne scar treatment cost in Singapore?

Acne scar removal treatment cost in Singapore varies depending on the modality used, the number of sessions required, and the complexity of the individual scar profile. Fractional CO2 laser and subcision procedures are generally priced higher than Pico laser treatments, reflecting their procedural depth and recovery profile. A precise, itemised cost estimate is provided following a clinical assessment at Glowwis, as scar severity and the required number of sessions differ significantly between individuals.

Why are at-home treatments often insufficient for acne scars?

Over-the-counter topical products — including retinol serums, vitamin C formulations, and AHA-based exfoliants — can improve surface pigmentation and skin texture to a limited degree. However, they do not penetrate the deep dermal layers where the structural damage of acne scarring occurs. Clinical procedures such as subcision, fractional CO2 laser, and TCA CROSS are required to address fibrous tethering and collagen depletion at their source.

Can severe acne scars be completely removed?

Complete removal of severe acne scars is not currently achievable through any single clinical treatment. However, significant visible improvement is well-supported by published evidence. Depending on scar type, treatment modality, and individual patient factors, studies report improvement rates generally ranging from 31% to over 78%, with combination therapy for acne scars tending to yield the highest outcomes. Individual results vary.

How many sessions of acne scar treatment are typically needed?

The number of sessions required depends on scar type and severity. Ice-pick scars treated with TCA CROSS may require two to four sessions spaced four to six weeks apart. Fractional CO2 laser for boxcar and rolling scars is typically performed across three to five sessions. Subcision for acne scars may be repeated based on clinical response and is frequently combined with other modalities. Your doctor will recommend a programme based on your specific clinical assessment.

What is the difference between rolling scars and ice-pick scars?

Rolling scars present as a wavy or undulating skin texture caused by fibrous bands in the deep dermis physically tethering the skin surface downward. They require subcision — a minimally invasive procedure that severs these bands — often combined with a biostimulator such as Rejuran S. Ice-pick scars are narrow, deep pits that penetrate the full thickness of the dermis. They respond to targeted reconstruction using TCA CROSS or, in some cases, punch excision.

What is the social downtime for laser acne scar treatments?

Social downtime varies by modality. Pico laser typically involves one to three days of mild redness and sensitivity. RF microneedling may produce pinpoint micro-crusting for two to four days. Fractional CO2 laser resurfacing carries a more significant recovery period of five to seven days, during which the skin undergoes active regeneration. Subcision may produce bruising that resolves over seven to ten days. Your doctor will advise on the specific recovery profile for your treatment plan.

Is acne scar treatment in Singapore suitable for darker skin tones?

Yes, though the choice of modality is an important clinical consideration. Certain laser technologies carry a higher risk of post-inflammatory hyperpigmentation in Fitzpatrick skin types IV–VI, which are common among patients of Asian, South Asian, and Malay descent in Singapore. RF microneedling, Pico laser, and subcision are generally regarded as safer options for darker skin tones. A thorough skin type assessment is conducted at Glowwis prior to any procedural recommendation.

What is TCA CROSS and when is it used for acne scars?

TCA CROSS (Chemical Reconstruction of Skin Scars) involves the precise application of high-concentration trichloroacetic acid to individual acne scar pits — specifically ice-pick and narrow boxcar scars. The controlled chemical injury stimulates collagen synthesis within the scar channel, gradually filling and reconstructing it from the base upward. It is a highly targeted procedure used as part of a combination protocol rather than as a standalone treatment.

How does subcision for acne scars work?

Subcision is a minimally invasive procedure in which a fine needle or cannula is inserted beneath the skin surface to mechanically sever the fibrous bands that tether rolling scars downward. Once released, the skin surface can elevate and assume a more natural contour. Subcision is frequently combined with a biostimulator or dermal filler to support the newly released tissue and reduce the likelihood of re-tethering during healing.

How do I know which acne scar treatment in Singapore is right for me?

Scar type is the primary determinant of treatment selection. Ice-pick scars respond to TCA CROSS or punch excision. Boxcar scars are addressed with fractional CO2 laser or RF microneedling. Rolling scars require subcision, often combined with a volumiser. Hypertrophic scars are managed with steroid injections or vascular lasers. Most patients present with a mix of scar types, requiring a tailored combination approach. The only reliable way to determine the right protocol is through a clinical skin assessment with a doctor experienced in acne scar management in Singapore.
