What Is It

Understanding Acne Scars

Reviewed by Dr. Minu Liz Mathew, MBBS MD DVL — February 2026

Acne scars form when severe breakouts damage the deeper layers of skin, destroying collagen and leaving behind depressions or raised marks. In Indian skin (Fitzpatrick IV–VI), scarring is frequently accompanied by persistent post-inflammatory hyperpigmentation (PIH), making the damage doubly visible. The type of scar — ice pick, boxcar, or rolling — determines which treatment works best. DermaVue dermatologists use a combination of fractional CO2 laser resurfacing, radiofrequency microneedling, PRP therapy, and subcision to stimulate collagen regeneration and rebuild scar tissue from within.

Acne scarring results from aberrant wound healing following inflammatory acne lesions, characterised by dysregulated collagen remodelling within the dermis. Atrophic scars — classified as ice pick (narrow, deep, V-shaped), boxcar (broad, sharply demarcated), and rolling (broad, undulating) — arise from excessive matrix metalloproteinase (MMP) activity and collagen III-to-I ratio imbalance during the proliferative phase of repair.[1] Hypertrophic and keloid variants reflect excessive collagen deposition with elevated TGF-beta signalling. Indian Fitzpatrick IV–VI phototypes present a dual challenge: concurrent post-inflammatory hyperpigmentation from melanocyte hyperactivity alongside structural dermal loss, requiring treatment protocols that balance aggressive collagen induction with melanocyte-safe parameters to avoid paradoxical hyperpigmentation.

Signs & Symptoms

What does Acne Scars look like?

Symptoms range widely in severity. Identifying which type you have determines the right treatment.

Ice Pick Scars
Narrow, deep, V-shaped pits that extend into the dermis or subcutis. Most difficult scar type to treat. Common on cheeks and temples.
Severe
Boxcar Scars
Broad, rectangular depressions with sharply defined vertical edges. Resemble chickenpox scars. Respond well to fractional laser and subcision.
Mod. Severe
Rolling Scars
Wide, shallow undulations caused by fibrous tethering bands beneath the skin. Give the skin a wave-like, uneven texture. Best addressed with subcision + filler.
Mod. Severe
Hypertrophic Scars
Raised, firm, pink or red scars that remain within the boundaries of the original wound. More common on the chest, back, and jawline.
Mod. Severe
Keloid Scars
Raised, firm scars that extend beyond the original wound margin. More prevalent in darker skin types. Require intralesional steroid or 5-FU injection.
Severe
Post-Inflammatory Hyperpigmentation
Flat dark brown or black marks at sites of healed acne. Not true scars but extremely common and persistent in Fitzpatrick IV–VI Indian skin.
Moderate
Post-Inflammatory Erythema
Flat pink or red marks remaining after acne heals. More visible in lighter skin tones. Fades over 3–12 months; vascular laser can accelerate clearance.
Mild
Scar-Bound Skin Tethering
Fibrous bands anchoring skin to deeper tissue, causing visible dimpling on facial animation. Released with subcision under local anaesthesia.
Mod. Severe
Root Causes

What actually causes Acne Scars?

Multiple factors act together — understanding them helps prevent recurrence after treatment.

Delayed or Inadequate Acne Treatment
Inflammatory acne left untreated for months causes prolonged dermal damage, increasing scar depth and extent. Early dermatologist intervention is the single best scar prevention strategy.
👆
Picking, Squeezing & Popping Lesions
Manual extraction of cystic or nodular acne ruptures the follicular wall deeper into the dermis, spreading infection and worsening tissue destruction. Extremely common habit in teenagers.
🧬
Genetic Predisposition
Wound healing capacity is genetically determined. Some individuals produce less collagen during repair, resulting in atrophic scars, while others overproduce collagen leading to keloids — especially in Fitzpatrick V–VI skin.
Severe Inflammatory Acne (Grade III–IV)
Nodular and cystic acne causes the deepest dermal destruction. The inflammatory cascade triggered by C. acnes activates MMPs that degrade the collagen matrix faster than it can be repaired.
🧴
Topical Steroid Misuse
Self-prescribed steroid creams — widely sold over the counter in India — cause dermal atrophy, impair collagen synthesis, and worsen acne (steroid acne), compounding scar formation.
🌡
Recurrent Acne Flares
Repeated inflammation at the same site causes cumulative collagen loss with each cycle. Inadequate maintenance therapy after initial clearance is a major contributor.
Abnormal Wound Healing Response
Elevated MMP-1 and MMP-3 activity combined with reduced TGF-beta1 signalling during the remodelling phase leads to excessive collagen degradation — the fundamental mechanism behind atrophic scar formation.
Who gets acne scars in India?
  • 95% of acne patients develop some degree of scarring — ranging from subtle textural irregularities to deep pitted scars
  • Fitzpatrick IV–VI skin (majority of Indian population) faces dual burden of atrophic scars plus persistent PIH lasting 6–24 months
  • Males more likely to develop severe nodulocystic acne and consequently deeper scarring, while females more prone to PIH
  • Delayed treatment is the #1 modifiable risk factor — average Indian acne patient waits 14 months before consulting a dermatologist
  • Kerala's humid climate increases acne severity through elevated sebum production, indirectly raising scarring risk in untreated patients
Diagnosis Process

What happens at your DermaVue consultation?

A structured clinical assessment — not a quick glance and a prescription pad. Here's exactly what to expect.

01
Scar Type Classification
Dermatologist visually classifies each scar as ice pick, boxcar, rolling, hypertrophic, or keloid. Dermoscopy and cross-polarised photography used for precise assessment. Baseline standardised photos taken.
02
Scar Severity Grading
Quantitative grading using Goodman & Baron qualitative scale (Grade 1–4) or ECCA grading system. Scar depth measured via optical profilometry where available. Guides treatment intensity selection.
03
Active Acne Assessment
Any active acne must be fully controlled before scar treatment begins — treating scars over active lesions worsens outcomes and risks new scarring. Isotretinoin clearance period (6 months) confirmed if applicable.
04
Fitzpatrick Phototype & PIH Evaluation
Skin phototype documented to determine safe laser parameters. Existing PIH mapped and graded. Higher Fitzpatrick types require modified energy settings to avoid post-inflammatory hyperpigmentation from treatment itself.
05
Personalised Multi-Modal Treatment Plan
Written protocol combining 2–3 complementary techniques (e.g., subcision + fractional laser + PRP) tailored to scar morphology, skin type, downtime tolerance, and budget. Expected improvement percentage discussed transparently.

Acne Scars treatments we offer

All procedures by board-certified MD DVL dermatologists. US-FDA approved equipment. No technician-only protocols — ever.

CO2 Fractional Laser
Micro-ablative columns penetrate the dermis, triggering neocollagenesis and elastic fibre remodelling. Gold standard for moderate–severe atrophic scars. 50–70% scar depth improvement over 3–5 sessions.
Boxcar & rolling scars (moderate–severe)
Radiofrequency Microneedling
Insulated microneedles deliver bipolar RF energy directly into the dermal scar bed, stimulating collagen I and III synthesis with minimal epidermal damage — safer for Indian skin tones than ablative lasers alone.
All atrophic scar types in Fitzpatrick IV–VI
PRP (Platelet-Rich Plasma)
Autologous growth factor concentrate injected or microneedled into scar tissue accelerates fibroblast proliferation and collagen deposition. Enhances results when combined with laser or microneedling.
Adjunct to laser/microneedling for deeper scars
Subcision
Tri-bevelled needle or cannula inserted beneath tethered scars to release fibrous bands anchoring skin to deeper tissue. Immediate visible improvement in rolling scars. Often combined with filler or PRP.
Rolling scars with dermal tethering
Dermal Fillers (Hyaluronic Acid)
Cross-linked hyaluronic acid injected beneath individual scars provides immediate volumetric correction. Results last 6–18 months. Ideal for select deep boxcar or rolling scars that need instant improvement.
Deep individual boxcar or rolling scars
Chemical Peels (Medium-Depth)
TCA CROSS (Chemical Reconstruction of Skin Scars) at 70–100% concentration applied focally into ice pick scars stimulates localised collagen production and scar elevation over 3–6 sessions.
Ice pick scars & superficial textural irregularities
Chemical Peels + Depigmenting
Sequential glycolic or mandelic acid peels combined with tyrosinase inhibitors (kojic acid, arbutin, tranexamic acid) to address concurrent PIH alongside scar treatment — essential in Fitzpatrick IV–VI patients.
Post-inflammatory hyperpigmentation with mild scarring

Treatment Journey

Your Acne Scars treatment timeline

Results are gradual, progressive, and lasting with the right protocol.

Week 1
Consultation, scar classification & baseline photography. Active acne status confirmed. Fitzpatrick-adjusted treatment plan finalised.
If active acne present, clearance protocol initiated first. Scar treatment deferred until skin is lesion-free for 4–6 weeks.
Month 1–2
First scar treatment session — fractional CO2 laser, RF microneedling, or subcision depending on scar type. Post-procedure redness resolves in 5–7 days.
Strict sun avoidance and barrier repair protocol. PIH prophylaxis with topical tranexamic acid or arbutin if Fitzpatrick IV+.
Month 3–4
Second and third sessions completed at 4–6 week intervals. Early collagen remodelling visible — scar edges softening, skin texture improving. 25–40% improvement expected.
PRP added as adjunct if response suboptimal. Subcision performed for residual tethered scars between laser sessions.
Month 5–8
Fourth to sixth sessions. Cumulative collagen induction reaching peak effect. 50–70% overall scar improvement in most patients. PIH fading significantly.
Treatment intervals may extend to 6–8 weeks. Dermal filler considered for select persistent deep scars.
Month 9–12
Maintenance phase. Collagen remodelling continues for 6–12 months after last session. Final result assessment at 12 months. Quarterly follow-up recommended.
Most patients achieve 50–75% scar improvement. Residual scars can be further refined with maintenance sessions annually.
FAQ

Frequently asked questions about Acne Scars

Untreated atrophic acne scars (ice pick, boxcar, rolling) are permanent — they do not fade or fill in on their own because the collagen matrix has been structurally destroyed. However, modern treatments like fractional CO2 laser, RF microneedling, and subcision can achieve 50–75% scar depth improvement over a course of 3–8 sessions. Flat dark marks (PIH) are not true scars and do fade, though in Indian skin this can take 6–24 months without treatment.

There is no single best treatment — the optimal approach depends on scar type. Ice pick scars respond best to TCA CROSS chemical reconstruction. Boxcar scars improve most with fractional CO2 laser. Rolling scars require subcision to release tethering bands, often followed by PRP or filler. Most patients need a combination of 2–3 techniques. A dermatologist assessment is essential to match treatment to your specific scar pattern and skin type.

DermaVue consultation fee is ₹300 at most branches. Fractional CO2 laser sessions range ₹5,000–12,000 per session depending on area treated. RF microneedling starts at ₹4,000 per session. PRP sessions ₹3,500–6,000. A full course of 4–6 sessions with combination treatment is discussed transparently at your first consultation — no hidden charges or pressure for packages.

Yes, but treatment parameters must be carefully adjusted for Fitzpatrick IV–VI skin. Higher melanin content increases risk of post-treatment hyperpigmentation if aggressive settings are used. DermaVue dermatologists use melanocyte-safe fractional laser settings, RF microneedling (which bypasses the epidermis), and pre-treatment depigmenting protocols to ensure safe, effective scar reduction in darker skin tones.

Most patients require 3–8 sessions spaced 4–6 weeks apart, depending on scar severity and type. Mild textural scars may show satisfactory improvement in 3–4 sessions. Moderate-to-severe ice pick and boxcar scars typically need 5–8 sessions of combination therapy. Collagen remodelling continues for 6–12 months after the last session, so final results are assessed at the 12-month mark.

Downtime varies by procedure. Fractional CO2 laser causes 5–7 days of redness and mild peeling. RF microneedling has 2–3 days of redness. Subcision may cause mild bruising for 5–7 days. Chemical peels have 1–3 days of mild flaking. Most patients return to work within 3–5 days after laser sessions. DermaVue schedules procedures to minimise social downtime based on your preference.
