Boxcar, Rolling or Icepick: Matching Acne Scar Type to Treatment
Dolce Estetica Medical Team · 9 min read · 13 August 2026
The short answer
Atrophic acne scars fall into three main shapes. Icepick scars are narrow and deep, and respond best to focal techniques rather than resurfacing alone. Boxcar scars are wider with sharp vertical edges, and respond to resurfacing such as fractional CO2 laser and microneedling. Rolling scars are broad with sloping edges caused by tethering beneath the skin, and usually need that tethering released rather than surface resurfacing. Most faces have a mix, which is why single-treatment plans usually underperform.

Why does scar shape decide the treatment?
Because each shape represents a different structural problem. A narrow deep track, a sharp-walled depression and a broad tethered dip are three different anatomical situations, and a treatment that addresses one may do very little for another.
This is the most common reason patients feel a course of treatment underdelivered. They were treated for the category of acne scarring rather than for the specific scars on their face, and the scars that did not respond were the ones the chosen treatment was never going to reach.
How do I recognise each type?
| Type | What it looks like | Underlying problem | Usual approach |
|---|---|---|---|
| Icepick | Small, narrow, deep — like a pinprick or a puncture | A narrow tract extending deep into the skin | Treated focally, spot by spot, rather than by resurfacing the whole face — broad resurfacing rarely reaches the base |
| Boxcar | Round or oval depression with sharp, steep edges | Loss of tissue with defined vertical walls | Fractional CO2 laser or microneedling, to soften the edges across a course of sessions |
| Rolling | Broad, shallow, wave-like undulation; skin looks uneven in raking light | Fibrous bands tethering the skin to deeper tissue | The tethering has to be released; resurfacing the surface alone under-treats these |
| Hypertrophic / keloid | Raised, firm, sometimes itchy — more common on jaw, chest, back | Excess collagen deposition during healing | Managed very differently — resurfacing is not the answer and can worsen them |
How many sessions will I need?
For fractional resurfacing of boxcar and mixed scarring, three to six sessions spaced roughly four to eight weeks apart is a common plan, with improvement continuing for several months after the final session as collagen remodels. Rolling scars often need their tethering addressed in one to three procedures before resurfacing adds much. Icepick scars are typically treated focally over repeated visits.
Honest framing: acne scar treatment produces improvement, not erasure. A realistic goal is meaningful softening of texture and shadow so that scars become far less noticeable in normal light. Complete restoration to pre-acne skin is not an outcome any clinic can promise.
What does acne scar treatment cost in India?
| Factor | Why it changes the figure |
|---|---|
| Which scar types you have | Spot-by-spot treatment of a few deep scars costs far less than resurfacing a whole face |
| Area treated | A small area is a fraction of a full face |
| Which treatment is chosen | Peels, microneedling and fractional CO2 sit at different price points |
| Length of the course | Set after assessment, then quoted as one figure rather than per visit |
| Whether acne must be controlled first | Adds a stage before scar work begins |
We do not publish rates, because a figure quoted before anyone has looked at your skin is guesswork. What we do commit to is that the full cost is itemised and agreed with you at consultation, before any treatment begins, with nothing added afterwards.
What are the risks on Indian skin?
The main concern with resurfacing on Fitzpatrick IV to V skin is post-inflammatory hyperpigmentation — darkening of the treated area during healing. It is usually temporary but can take weeks to months to settle, and it is the reason conservative settings, careful patient selection and strict aftercare matter more here than in lighter skin.
- Post-inflammatory hyperpigmentation — the most common issue; minimised by conservative settings, sun avoidance and pre-treatment preparation of the skin.
- Prolonged redness after fractional resurfacing — expected for days, occasionally longer.
- Infection or delayed healing — uncommon, but why aftercare instructions are specific rather than general.
- Worsening of raised scarring in keloid-prone individuals.
- Active acne must be controlled before scar treatment begins — treating scars while acne is active means creating new ones.
What should I ask at consultation?
- Which scar types do I actually have, and can you show me on my own face?
- Which of my scars will this treatment help, and which will it not?
- How many sessions before we reassess, and what will we do if response is poor?
- What is the plan if I develop pigmentation afterwards?
- Does my acne need to be controlled first?
Frequently asked questions
What are the different types of acne scars?
Depressed (atrophic) acne scars are usually grouped as icepick — narrow and deep; boxcar — wider with sharp vertical edges; and rolling — broad and shallow with sloping edges caused by tethering beneath the skin. Raised hypertrophic and keloid scars are a separate category treated very differently.
Which treatment is best for rolling acne scars?
Rolling scars are caused by fibrous bands tethering the skin to deeper tissue, so they generally need that tethering released rather than surface resurfacing alone. Resurfacing may be added afterwards, but used by itself it commonly under-treats this scar type.
How many CO2 laser sessions do I need for acne scars?
CO2 laser for acne scars is given as a course spaced weeks apart, with improvement continuing for months afterwards as collagen remodels. The number of sessions depends on your scar type, depth and how your skin responds, and is decided after assessment rather than promised in advance.
Can acne scars be removed completely?
No. Acne scar treatment produces improvement rather than erasure. A realistic goal is meaningful softening of texture and shadow so scars become far less noticeable in normal light. Complete restoration to pre-acne skin is not an achievable promise.
Is CO2 laser safe for Indian skin?
It is used on Indian skin, with the main concern being post-inflammatory hyperpigmentation during healing. This risk is managed with conservative settings, preparation of the skin beforehand, strict sun avoidance and careful patient selection. Suitability is assessed individually.
Should I treat active acne before treating scars?
Yes. Active acne needs to be controlled first. Treating scars while acne is still active risks creating new scars, and inflamed skin responds less predictably to resurfacing.
What does acne scar treatment cost in Kochi or Calicut?
Cost is driven by which scar types you have, how large an area needs treating, which treatment is chosen and how long the course runs. Treating a few individual deep scars costs far less than resurfacing a full face. We give you the complete figure at consultation, itemised, once your skin has been examined.
