Acne scars
Last reviewed
Acne scars are permanent skin texture changes left behind after inflammatory or nodulocystic acne. They come in three main types — ice-pick (narrow deep pits), rolling (wavy depressions) and boxcar (sharp-edged depressions) — and respond to different procedures. Microneedling-RF, subcision, TCA CROSS and chemical peels each have a role. Treatment improves but rarely fully erases scarring; realistic improvement is 50–80% over 6–12 months.
Acne scars are the most over-treated and under-counselled problem in cosmetic dermatology. Patients walk in expecting one laser session will erase years of scarring; they walk out (from somewhere else) months later, ₹2 lakh poorer and not much smoother.
Real scar revision is patient work. Different scar types respond to different procedures; most patients have a mix of types and need a combination plan. The realistic goal is meaningful improvement — typically 50–80% — over 6–12 months, not perfection in three sessions.
Types of acne scars
- Ice-pick scars — narrow (<2 mm), deep pits that look like the skin was punctured
- Rolling scars — wavy, broad depressions giving the skin an undulating texture
- Boxcar scars — round or oval depressions with sharp vertical edges
- Hypertrophic / keloid scars — raised, thickened scars (more common on chest, back, jawline)
- Post-inflammatory hyperpigmentation (PIH) — brown marks; technically not scars but often mixed in
- Post-inflammatory erythema (PIE) — red marks; resolves slowly without active treatment
- Most patients have a mix of types on the same face
Why acne scars form
- Severity — nodulocystic and inflammatory acne scar much more than comedonal
- Duration — acne that lasts years scars more than acne treated early
- Picking — manual extraction extends inflammation and deepens scarring
- Genetic predisposition — some skin types scar more readily than others
- Delayed treatment — the strongest single predictor of scar burden
- Family history of keloid formation (for the hypertrophic/keloid scar subset)
When to see a dermatologist
See a dermatologist once active acne has been calm for 3–6 months — scar work on an inflamed face usually makes new marks. Earlier consultations are still useful: we plan the scar revision timeline alongside the acne plan, so you're ready to start as soon as the inflammation settles.
How acne scars is treated at SkinWise
We assess the scar mix and stage a plan. Rolling scars usually respond best to microneedling-RF (4–6 sessions). Boxcar scars need a combination of microneedling-RF and chemical peels. Ice-pick scars respond to TCA CROSS (a focal high-concentration peel). Subcision is added for deep tethered scars. Skin colour and texture continue improving for 3–6 months after the last session — the result isn't visible the day after treatment.

Frequently asked questions
Can acne scars be completely removed?
Realistically no — but they can be meaningfully improved, usually by 50–80% over a course of treatment. Anyone promising 100% erasure of scarring is overselling. We discuss expected improvement per scar type at the first consult.
How many sessions will I need?
Typical plans are 4–6 microneedling-RF sessions over 6–9 months, often with peels or TCA CROSS in between. Severe mixed scarring may need 6–12 months total. Maintenance sessions yearly help hold the result.
Will lasers work on my skin tone?
Fractional CO2 and erbium lasers can work on Indian skin but have a higher pigmentation risk than microneedling-RF. For Fitzpatrick III–V we typically prefer microneedling-RF as first-line; ablative lasers are reserved for select cases on stable, well-prepared skin.
What about subcision and fillers?
Subcision (a needle technique that releases tethered scars from below) is excellent for deep rolling scars. Hyaluronic-acid filler can temporarily smooth depressed scars but needs maintenance every 12–18 months; we consider it for specific cases rather than as a primary scar treatment.

A focused 15-minute first consultation is where we slow down, map your concern and build the smallest plan that will actually move the needle. No oversell, no fixed menu.
