Acne Scars: How to Match the Right Treatment to Your Scar Type

The single most common reason acne scar treatment disappoints is that the treatment was matched to the patient rather than to the scar. Two people with what looks like the same damaged cheek can need completely different procedures.

Use good side lighting and a mirror. Flat marks that you can only see, not feel, are pigment or vascular marks rather than scars. Depressions you can feel with a fingertip are atrophic scars, and they divide into three shapes. Raised, firm scars are hypertrophic or keloid scars and follow different rules again.

Icepick scars are narrow, deep, and steep-sided, like a puncture through the skin. Boxcar scars are wider with defined vertical edges, like a small crater with a flat floor. Rolling scars are broad and shallow with soft sloping edges, giving the skin an undulating look because the scar base is tethered to deeper tissue.

Most patients have a mixture. That is normal, and it is why a serious plan almost always combines techniques rather than repeating one.

Treating scars while acne is still active is money spent on ground that keeps moving. New lesions create new scars, and several scar procedures are unsafe or unwise on inflamed skin.

If you are still getting regular breakouts, the correct sequence is medical acne control first, held stable for a period, and only then a scar plan. This is frustrating advice and it is also the advice that produces the better final result.

Any clinic willing to start resurfacing an actively inflamed face is prioritising the booking over the outcome.

Rolling scars are tethered downwards by fibrous bands connecting the skin to deeper tissue. That is a mechanical problem, and no amount of surface resurfacing solves it. The standard technique is subcision, in which a fine needle or cannula is passed under the scar to divide the tethering bands so the skin can lift.

Subcision is usually done under local anaesthesia, causes bruising for about a week, and is often repeated over two or three sessions. Results build as the released space fills with new collagen. Some patients benefit from placing a small amount of filler or a biostimulatory agent into the released space to hold the lift.

Systematic reviews of non-energy-based acne scar techniques consistently place subcision as a core treatment for tethered rolling scars, and it is one of the most satisfying procedures to watch work when patient selection is right.

Icepick scars are too narrow and too deep for surface resurfacing to reach the base. The usual approach is focal chemical reconstruction, known as TCA CROSS, where a high concentration of trichloroacetic acid is applied precisely into the scar opening with a fine applicator. The scar floor is deliberately injured so it heals with new collagen, gradually raising it.

This requires multiple sessions, typically three to six spaced about a month apart, and each session produces a small white frost and then a scab in the treated points for several days. On darker skin types, this is done conservatively because the treated points can darken temporarily during healing.

Very deep single icepick scars are sometimes better excised with a tiny punch and closed, then resurfaced later once healed.

Boxcar scars with defined edges and rough overall texture are where fractional resurfacing earns its reputation. Ablative fractional CO2 laser vaporises microscopic columns of tissue and stimulates collagen remodelling over the following months, softening scar edges so they blend with surrounding skin.

Microneedling, and radiofrequency microneedling, work along similar principles with less downtime and generally less improvement per session. Comparative reviews of needling techniques against ablative fractional lasers show both improve atrophic scarring, with lasers typically achieving more per session in exchange for a longer recovery. The right answer depends on how much downtime your life allows.

For patients in Rawalpindi and Islamabad with medium to deep skin tones, conservative settings across more sessions are safer than a single aggressive treatment, because the main risk is temporary post-inflammatory darkening during healing rather than the procedure itself.

Post-inflammatory hyperpigmentation, the brown marks common in South Asian skin, responds to daily broad-spectrum sun protection, topical agents such as azelaic acid, retinoids, and other pigment-directed prescriptions, and superficial chemical peels. Given time and sun discipline it improves substantially without any device.

Post-inflammatory erythema, the flat red or purple marks more visible in lighter skin, fades slowly and can be helped by vascular-directed treatment. Neither of these needs a resurfacing laser, and treating them as if they were scars is a common and expensive mistake.

A useful test: stretch the skin gently. If the mark stays flat and only the colour is abnormal, you are treating pigment. If a depression appears or deepens, you are treating a scar.

Hypertrophic and keloid scars, most often on the jawline, chest, shoulders, and back, involve too much collagen rather than too little. The management is the opposite of atrophic scars: intralesional steroid injections, sometimes combined with other agents, silicone therapy, and pressure, with resurfacing avoided or used with great caution.

If you have a personal or family history of keloids, tell your clinician before any procedure. It changes what is safe to offer you.

A typical combined plan runs six to twelve months: acne stabilised, then subcision for tethered scars, focal work such as TCA CROSS for icepick scars, and fractional resurfacing to blend texture, with several months at the end simply for collagen remodelling before the final assessment.

Expect meaningful improvement rather than erasure. In published series, well-selected patients commonly report substantial improvement in scar depth and appearance, and no technique reliably restores perfectly smooth skin. Any clinic offering that is overpromising.

Sun protection runs through the entire plan. In Pakistani sunlight, skipping sunscreen after a scar procedure is the fastest way to convert a good technical result into a pigmentation problem that then takes months to settle.

If you want to know which of these categories your scars fall into, book a consultation at Ayra Aesthetics & Dental Lounge and ask specifically for a scar-type assessment rather than a treatment quotation. The assessment is what determines everything else.
