Acne usually clears. The texture it leaves behind often doesn’t, and that’s the part people tend to find hardest. You did the courses, you waited it out, the breakouts finally stopped, and what’s left is a surface that catches the light in ways you’d rather it didn’t.

Treatment options have improved a lot over the past decade, and most scar types will respond to something. What they will not do is vanish. Any clinic that blurs that line is setting you up to be disappointed six months down the track, so it is worth hearing plainly at the start.

Infinity Skin Clinic has been performing laser-based acne scar treatment in Sydney since 2004. Over that time one thing has held true: the results come from matching the treatment to the scar, not from any single device. A rolling scar and an ice pick scar sit on the same face and need completely different approaches.

This guide walks through what causes acne scars, the different types and how to recognise yours, which treatments suit which scars, and what recovery and results actually look like.

What causes acne scars?

Scarring starts with inflammation. When a deep, inflamed acne lesion damages the dermis, the skin has to repair itself, and that repair process doesn’t always run smoothly. Collagen production either falls short or overshoots.

When it falls short, you get atrophic scars, which are depressions where tissue has been lost. These are by far the most common. When it overshoots, you get hypertrophic or keloid scars, which sit raised above the surrounding skin. Picking and squeezing active spots pushes inflammation deeper and makes both outcomes more likely, which is the practical reason every clinician nags about it.

DermNet notes that scarring affects around 30 per cent of people with moderate or severe acne vulgaris, so if you’re dealing with this you’re in substantial company.

One distinction saves a lot of unnecessary worry. Post-inflammatory erythema (PIE), the flat pink or red marks left after a spot settles, and post-inflammatory hyperpigmentation (PIH), the flat brown marks, are not true scars at all. The skin surface is intact. They’re discolouration, they often fade on their own given time, and they respond well to light-based treatment. True textural scars are a different problem, because the shape of the skin has changed and only collagen remodelling will shift it.

Types of acne scars and why the type matters

Work out which of these you have and the treatment conversation becomes far more straightforward. Most people have a mix.

  • Rolling scars. Broad, shallow, wave-like depressions with sloping edges that give skin an uneven, undulating look, often across the cheeks. They’re caused by fibrous bands tethering the skin down to deeper tissue, which is why resurfacing the surface alone tends to underdeliver. Releasing the tether matters as much as rebuilding collagen.
  • Boxcar scars. Round or oval depressions with sharp, defined vertical walls, a bit like a shallow crater. These respond comparatively well to fractional ablative laser and to microneedling, because the edges can be softened and the base lifted with new collagen.
  • Ice pick scars. Narrow, deep, V-shaped pits that look like the skin has been punctured. These are the most stubborn type. They extend too deep for broad resurfacing to reach the base, so they usually need techniques that target each scar individually rather than treating the whole face. Milder ice pick scarring can improve with fractional resurfacing.
  • Hypertrophic and keloid scars. Raised, firm, red to purple scars that are more common on the chest, back and shoulders than the face. These are managed quite differently from depressed scars, and they need individual medical assessment rather than a standard resurfacing plan.
  • Post-inflammatory erythema (PIE). Flat pink or red marks. Frequently mistaken for permanent scarring when they’re nothing of the sort. Vascular and light-based treatments such as BBL and Laser Genesis target the dilated vessels causing the colour.
  • Post-inflammatory hyperpigmentation (PIH). Flat brown or grey-brown marks, more common in darker skin types. Light-based treatment, pigment-targeting laser and topical actives are the usual approaches, alongside diligent sun protection.

If you’re not sure which you’re looking at, that’s completely normal. Scar types are easier to identify in person under proper lighting and magnification than in a bathroom mirror.

Acne scar treatments at Infinity Skin Sydney

As a rough rule, red and brown marks are treated with light-based devices, shallow texture with microneedling or a gentle fractional laser, and deeper atrophic scarring with ablative fractional resurfacing. The options below are the ones we use most, and what each one is suited to.

BBL Hero and Forever Clear BBL

BBL Hero delivers BroadBand Light to target the vascular and pigment components of post-acne marks, which makes it a strong option for PIE and superficial discolouration rather than for texture. Forever Clear BBL is the protocol aimed at active acne and the redness that comes with it. Neither involves downtime, so they fit around normal life easily. We’ve written separately about whether BBL Hero works on acne scars if you want the detail.

Halo hybrid fractional laser

Halo runs two wavelengths at once. One is ablative and removes microscopic columns of surface skin; the other is non-ablative and heats the tissue underneath. Working at both levels prompts a stronger collagen response than either does on its own, which is why Halo comes up so often in conversations about moderate boxcar and rolling scarring, and about general texture. Skin usually looks pink and feels rough for about 3 to 5 days afterwards.

ProFractional and Contour TRL laser resurfacing

ProFractional uses an ablative Erbium:YAG laser to create narrow channels deep into the dermis, prompting a strong collagen response from the base of the scar upward. Contour TRL is the full-field version, resurfacing the entire treated area rather than a fraction of it. This is the option for moderate to severe atrophic scarring, and it asks the most of you in return: depending on depth, recovery runs from around 5 days to as long as two weeks. It isn’t right for everyone and it’s assessed carefully.

Laser Genesis

Laser Genesis uses a non-ablative 1064nm Nd:YAG laser to gently warm the dermis. It works on PIE, background redness and mild textural change, with no downtime at all. On its own it won’t resolve deep scarring, but as an adjunct between stronger treatments, or as maintenance afterwards, it earns its place.

SkinPen microneedling

SkinPen creates controlled micro-channels that trigger the skin’s own repair response, known as collagen induction therapy. It’s well suited to mild and moderate rolling and boxcar scars, and because it uses no light energy it can be used across the full range of Fitzpatrick skin types with a low risk of pigment complications. Redness usually settles within 1 to 3 days.

Moxi laser

Moxi is the lighter sibling to Halo: non-ablative, fractional, 1927nm. It suits mild texture and PIH, and we use it often in deeper skin tones, where the stronger lasers carry a pigment risk we would rather avoid. MENDS follow for three to five days, the fine dark specks that come up as treated skin sheds.

Medical-grade skin peels

Medipeels are chemical exfoliation. Good for surface pigment, mild texture and general skin quality, and a gentle way in if a laser feels like a lot. They will not reach deeper scarring.

Why a combined approach usually works best

Almost nobody has just one kind of acne scarring. It is far more common to see rolling scars over the cheeks, a couple of boxcar scars near the jaw, redness that has not faded and one or two ice pick scars, all on the same face. No single device covers that spread well, which is why plans built around one treatment tend to stall partway.

The more effective approach layers techniques that do different jobs: something to release tethered scars, something to rebuild collagen at depth, and something to address the colour left behind. Some of these can be combined in a single visit, and some are better staged. Which combination suits you depends entirely on what your assessment shows, and techniques such as subcision, which releases the fibrous bands under rolling scars, are discussed individually rather than applied as a default.

Timing takes patience. With moderate scarring, most people are looking at 2 to 4 sessions spaced 8 to 12 weeks apart before they notice much. Those gaps are not padding. Collagen carries on remodelling for months after each session, so treating again too early means judging skin that has not finished responding. Our blog on which treatment is most effective for acne scars compares the options in more depth.

Do you need to clear active acne first?

Usually, yes. Moderate to severe active acne should be under control before most resurfacing treatments. Treating inflamed skin can aggravate it, and there’s little sense in resurfacing a surface that’s still actively forming new scars.

There’s some overlap, though. Forever Clear BBL and Laser Genesis can be used while mild active acne is still present, and for some patients that means starting on redness and early marks rather than waiting on the sidelines. Our team can map out a plan that addresses both where it’s appropriate.

One important thing to raise at consultation: if you have taken oral isotretinoin, a prescription acne medication, most clinicians recommend leaving a gap of roughly 6 to 12 months after finishing the course before ablative laser procedures, because skin healing is altered during and after treatment. Disclose every medication and supplement you’re taking, along with any recent sun exposure or tanning. It genuinely changes what we recommend.

Acne scar treatment for darker skin types

This deserves its own section, because it’s where a lot of generic advice falls down.

Melanin absorbs light energy. That means Fitzpatrick skin types IV to VI carry a higher risk of post-inflammatory hyperpigmentation after laser treatment, and some traditional ablative lasers carry meaningfully more risk than others. It isn’t a reason to avoid treatment. It’s a reason to choose it carefully and to have it done by someone who adjusts settings for skin tone rather than running a standard protocol.

For deeper skin tones, the treatments that come up most often are SkinPen microneedling, which uses no light energy at all, Moxi at 1927nm, Laser Genesis at 1064nm, and BBL kept at conservative settings. Halo can be used as well, with the parameters adjusted. Test patching first and building up in stages is often the sensible way to go.

Be straight with your clinician about your skin tone, how easily you tan, and any sun you have had recently. Tanned skin shifts the risk picture whatever your baseline tone is, and it is one of the more common reasons a treatment gets pushed back a few weeks.

What recovery actually looks like

Downtime varies enormously across these treatments, so it’s worth planning around.

  • Essentially none: Laser Genesis and BBL. Some warmth and pinkness for an hour or two. Moxi sits close to this, with 3 to 5 days of fine MENDS shedding.
  • Two to five days: Halo and SkinPen. Redness, swelling and a sandpapery texture that settles progressively.
  • Five to fourteen days: ProFractional and Contour TRL, depending on the depth treated. This is the one to book around a quiet stretch in your calendar.

Aftercare is much the same whatever you have had done. SPF50+ every day, sun avoidance that actually means it, gentle cleansing, and no retinoids or exfoliants until your clinician gives the go-ahead.

Sun is the step people cut corners on, and treated skin takes up pigment too easily for that. Cancer Council Australia advises a broad-spectrum, water-resistant SPF50 or SPF50+, reapplied every two hours.

As for results, the colour changes first. Redness and PIE often look better after one or two sessions. Textural improvement is the slow burn, developing over 3 to 6 months as new collagen matures and reorganises. Our article on what to expect from laser acne scar treatment covers the post-treatment period in more detail. All procedures carry risks, which you can read about here and which are discussed with you before anything is booked.

Frequently asked questions

What is the best treatment for acne scars in Sydney?

There is no single best treatment for acne scars, because the right choice depends on scar type, skin type and severity. Rolling and boxcar scars often respond to fractional laser or microneedling, red marks to light-based treatment, and ice pick scars to targeted techniques. Most plans combine more than one treatment.

How many treatments do you need for acne scars?

A course of two to four sessions, eight to twelve weeks apart, is typical for moderate acne scarring. Mild scarring can need fewer and severe scarring often needs more, so the number is worked out at assessment rather than set in advance. Collagen keeps remodelling for three to six months after each session, which means the result carries on developing between appointments.

Does laser treatment completely remove acne scars?

No. Laser treatment aims to reduce the appearance of acne scars rather than remove them entirely. The Australasian College of Dermatologists notes that acne scars may never completely disappear, though their appearance usually improves. The degree of improvement depends on scar type, severity and individual healing.

Is acne scar treatment painful?

That depends on the treatment. With light-based options such as BBL and Laser Genesis, most people describe brief warmth or a light snapping feeling. Ablative resurfacing, including Halo and ProFractional, is done under topical anaesthetic. Your clinician will talk you through what to expect before anything starts.

Can acne scar treatments be done on darker skin?

Yes, provided the treatment is chosen carefully. For Fitzpatrick skin types IV to VI, the non-ablative options are the ones used most often: Moxi, Laser Genesis and SkinPen microneedling. Ablative resurfacing can still be appropriate, but at conservative settings, because darker skin carries a higher risk of post-inflammatory hyperpigmentation. A skin type assessment guides that decision.
