Best Treatments for Acne Scars: Matching the Right Treatment to Your Scar Type

The best treatment for acne scars depends almost entirely on the kind of scar you have, and most people need a combination rather than a single fix. For narrow, deep ice pick scars, dermatologists lean on TCA CROSS or punch techniques. For broad, sloping rolling and boxcar scars, the workhorses are fractional laser resurfacing, RF microneedling, and subcision. Raised scars respond to steroid injections and silicone instead. Expect a series of three to six sessions for most in-clinic treatments, spaced four to six weeks apart, with collagen continuing to rebuild for three to six months after you finish. There is no cream that erases a true textural scar, and honestly, anyone promising a one-session miracle is selling something.

That is the short version. The longer version matters, because matching the treatment to the scar is the whole game here, and it is also where a lot of money gets wasted on the wrong approach.

Acne Scar Treatment at a Glance

• What actually works: In-clinic collagen-remodeling treatments, not topical scar creams, for indented (atrophic) scars
• Scar type decides everything: Ice pick, boxcar, rolling and raised scars each respond to different tools
• Typical sessions: 3 to 6 for microneedling or RF microneedling, 1 to 3 for fractional laser, spaced 4 to 6 weeks apart
• Realistic results: Most people see meaningful softening, roughly in the 40 to 70 percent range, not flawless skin
• Timeline: Early change in a few weeks, with collagen remodeling for 3 to 6 months after the last session
• Dark marks are different: Flat brown or red marks are not scars and usually fade with time, sunscreen and the right actives
• First step: An in-person assessment to identify your scar types, since most faces have a mix

Key Terms, Defined

• Atrophic scars: Depressed or pitted scars where the skin lost tissue. Ice pick, boxcar and rolling scars all fall here, and they are the most common after acne.
• Hypertrophic and keloid scars: Raised scars from excess collagen. More common on the chest, back and jaw than the cheeks.
• Post-inflammatory hyperpigmentation (PIH): Flat brown or tan marks left after a breakout. A pigment issue, not a scar.
• Post-inflammatory erythema (PIE): Flat pink or red marks, more common on lighter skin. Also not a scar.
• Collagen induction: The controlled micro-injury that treatments like microneedling use to prompt the skin to lay down new collagen.
• Subcision: A minor procedure that releases the fibrous bands tethering a rolling scar down.
• TCA CROSS: A technique that places a tiny drop of high-strength trichloroacetic acid into an ice pick scar to rebuild it from the base.

One caution before we go further. This is general education, not a treatment plan. Scar type, skin tone and your history all change what is safe and sensible for you, and that read really does need a professional looking at your skin in person. I have seen people talk themselves into aggressive lasers for scars that would have responded to something gentler, and the reverse too.

Key Takeaways

• Acne scars are not all the same. Indented scars, raised scars and flat discolouration each need a different approach, so the first job is figuring out what you actually have.
• In-clinic treatments are the reliable route for true textural scars. Microneedling, RF microneedling, fractional laser and minor procedures like subcision do the heavy lifting.
• Most people need a series, and often a combination. One treatment rarely addresses a mixed set of scars well.
• Results are real but partial. Think meaningful improvement over months, not perfectly smooth skin overnight.
• Dark and red marks are not scars and usually fade on their own, faster with sunscreen and the right topicals.
• Skin tone matters for safety. Deeper skin needs more conservative settings and careful device choice to avoid pigment problems.
• A consultation saves money. It sorts your scar types and rules out wasting a treatment that was never going to help.

What Are Acne Scars, Really?

An acne scar is a permanent change in the skin’s texture left behind after inflammation damages the deeper layer, the dermis. When a breakout, especially a deep cystic one, destroys collagen, the skin heals imperfectly. Sometimes it loses tissue and leaves a dent. Sometimes it makes too much collagen and leaves a bump. Either way, the surface is no longer smooth, and that textural change is what separates a scar from a mark.

This is the distinction that trips most people up. A flat brown spot or a lingering red patch where a pimple used to be is not a scar. It is discolouration, and it usually fades. You can confirm this with a simple test at home: run a finger over it, or look at it in raking side light. If the surface is level and only the colour is off, it is a mark. If you can feel or see an indentation or a raised ridge, that is a scar. The treatments for each are completely different, which is why getting this right early saves a lot of frustration.

True scars do not resolve on their own. They can be softened, sometimes dramatically, but the goal of treatment is improvement rather than erasure. I find it helps to set that expectation up front, because the before-and-after photos online tend to show the best possible outcomes under flattering light.

The Types of Acne Scars, and Why Type Decides Treatment

Dermatologists sort indented acne scars into three main shapes, and most faces carry a blend of them. The shape tells you a lot about which treatment has a real chance of working, because each type sits at a different depth and has a different structure.

Ice Pick Scars

These are narrow, deep and steep, like someone pressed a tiny awl into the skin. They are the hardest atrophic scars to treat because the damage goes deep while the opening stays tiny, so resurfacing the surface barely touches them. The techniques that actually reach them are TCA CROSS, which rebuilds the scar from the bottom, and punch excision, where a doctor removes the scar and lets it close as a much finer line. Search interest here is steady, with ice pick scars drawing around 1,000 searches a month in Canada, so plenty of people are trying to figure these out.

Boxcar Scars

Boxcar scars are wider than ice pick scars, with sharper, more defined edges and a flat floor, a bit like a shallow crater. Because they have more surface area, resurfacing treatments can genuinely help. Fractional laser resurfacing, RF microneedling and regular microneedling all work to smooth the edges and lift the floor over a series. Deeper boxcars sometimes need a punch technique first.

Rolling Scars

Rolling scars give the skin a wavy, undulating look rather than sharp pits. They are caused by fibrous bands tethering the surface down to the deeper tissue. The key with these is releasing those bands, which is what subcision does, often paired with microneedling or laser afterward to build collagen in the freed space. Sometimes a filler is used to lift the depression while the collagen catches up.

Hypertrophic and Keloid Scars

These are the raised ones, and they show up more on the jaw, chest and back than on the cheeks. They come from the skin overproducing collagen during healing. The approach flips entirely for raised scars: steroid injections to flatten them, silicone gels or sheets, and certain lasers. This is the group where microneedling and peels can actually make things worse, which is one more reason the right diagnosis matters before anyone touches your skin.

Scar type	What it looks like	Treatments that tend to work
Ice pick	Narrow, deep, steep-sided pits	TCA CROSS, punch excision, sometimes fractional laser
Boxcar	Wider pits with sharp edges and a flat base	Fractional laser, RF microneedling, microneedling, punch techniques for deep ones
Rolling	Wavy, sloping, tethered depressions	Subcision, then microneedling or laser; sometimes filler
Hypertrophic / keloid	Raised, firm bumps	Steroid injections, silicone, specific lasers
PIH / PIE (marks)	Flat brown or red discolouration	Sunscreen, retinoids, acids, peels, pigment or vascular lasers

Are Acne Scars Permanent? Can They Be Fully Removed?

True textural scars are permanent in the sense that they will not disappear on their own, and no honest clinic will promise to erase them completely. What treatment does is remodel the scar so it catches less light and blends more with the surrounding skin. The improvement can be significant, and for many people the scars become hard to notice in normal light, but “gone” and “much better” are not the same claim, and I would be wary of anyone who blurs that line.

The one group that often does clear up on its own is the marks. Post-inflammatory hyperpigmentation and redness are not scars, and they usually fade over a few months to a year. So part of the honest answer to “can acne scars be removed” is that some of what people call scars were going to fade anyway, and some genuinely needs treatment. Sorting which is which is step one.

Best Professional Treatments for Acne Scars, Compared

Here is how the main in-clinic options stack up. Think of this as a map rather than a ranking, since the right choice depends on your scar type, your skin tone and how much downtime you can take.

Microneedling

Microneedling is the gentle, flexible option a lot of people start with. A device studded with fine needles makes thousands of tiny channels in the skin, and the healing response lays down fresh collagen in the weeks that follow. It suits mild to moderate rolling and boxcar scars, and it is forgiving across skin tones, which is part of why it is so widely used. You can read more on our microneedling treatment page, and our guide to microneedling cost and sessions covers what a typical series involves. It is not a one-and-done treatment, though. Three to six sessions is the usual arc, and the results build slowly.

RF Microneedling (Morpheus8)

RF microneedling adds radiofrequency heat to the needling, which lets the energy reach deeper and tightens as it remodels. That makes it a strong pick for deeper rolling and boxcar scars, and for skin that has started to loosen a little alongside the scarring. Our Morpheus8 treatment page explains the device, and if you want to see how results actually progress, the Morpheus8 before and after timeline is a realistic look. One nice feature of RF microneedling is that it tends to be safer for deeper skin tones than aggressive ablative lasers, since much of the action happens below the surface.

Fractional Laser Resurfacing

Fractional lasers deliver energy in tiny columns, treating a fraction of the skin at a time so it heals faster than full resurfacing would. They are effective for generalized boxcar and rolling scars and for evening out tone at the same time. The trade-off is downtime, which runs longer with ablative lasers than with non-ablative ones. Clinics choose the device and settings based on your skin, and deeper skin tones usually call for a more conservative, non-ablative approach to avoid pigment shifts. If laser specifically is on your radar, our guide to laser treatments for acne scars goes deeper into the device options.

Subcision and Punch Techniques

Subcision is the answer for rolling scars that are being pulled down by fibrous bands underneath. A practitioner slides a needle or cannula under the scar and releases those tethers, which lets the surface lift. It is often combined with microneedling or laser afterward so new collagen fills the freed space. Punch excision is a different tool for a different scar: for a deep ice pick or a narrow boxcar, a doctor removes the scar entirely and closes the spot, trading a pit for a much finer, flatter line. Both of these are minor procedures, and they sit on the medical side of the line, so they are typically done or overseen by a physician.

TCA CROSS

TCA CROSS is a focused technique for ice pick scars, the ones nothing else seems to touch. A tiny amount of high-strength trichloroacetic acid is placed precisely into the scar, which prompts it to rebuild from the base over several treatments. It is oddly satisfying in concept, using controlled injury to fill a pit from the bottom up, though it does require patience and usually a few rounds.

Chemical Peels

Peels are more of a supporting player for true scars, but they earn their place for shallow texture, surface irregularity and especially the dark marks that often tag along. A peel removes the outer layers in a controlled way, which smooths the surface and fades pigment. Our chemical peel options are matched to your skin, and the chemical peels in Toronto guide and our breakdown of the best peel by skin type are both worth a look if you are weighing strengths.

Dermal Fillers and Steroid Injections

Filler can lift an individual depressed scar, giving an immediate improvement that lasts until the product breaks down, so it works as a bridge rather than a permanent fix. Steroid injections do the opposite job, flattening raised hypertrophic and keloid scars. Both are targeted tools for specific situations rather than general scar treatments.

Matching the Right Treatment to Your Scar Type

If you take one thing from this, let it be that the scar decides the treatment, not the other way around. Here is the quick logic a clinician runs through, simplified.

If you mainly have…	The usual starting point	Why
Ice pick scars	TCA CROSS or punch excision	They reach the deep, narrow damage that resurfacing misses
Boxcar scars	Fractional laser or RF microneedling	Enough surface area for resurfacing to smooth the edges
Rolling scars	Subcision, then microneedling or laser	Releasing the tethers has to come before rebuilding
Raised scars	Steroid injections, silicone, laser	The problem is too much collagen, so you flatten rather than build
A mix (most people)	A combination plan	Different tools for different scars, sequenced over time
Mostly flat marks	Topicals, sunscreen, maybe a peel	These are pigment or redness, not texture, and often fade

Most faces are a mix, which is why a single treatment often disappoints. A good plan might pair subcision for the rolling scars with TCA CROSS for a couple of ice pick scars and a few microneedling sessions to tie it all together. That kind of layering is normal, and it is also why mapping your scars first is money well spent.

What About the Dark Marks and Redness?

The flat marks left after acne are the part people most often misclassify as scars, so they deserve their own section. Brown marks are post-inflammatory hyperpigmentation, where the breakout triggered extra melanin. Pink or red marks are post-inflammatory erythema, essentially lingering dilated vessels, and they show up more on lighter skin. Both are flat, and both usually fade with time.

You can speed that along. Daily broad-spectrum sunscreen is non-negotiable, because sun exposure deepens brown marks and drags out the fading. Topical retinoids, vitamin C, azelaic acid and gentle exfoliating acids all help nudge pigment along. For stubborn brown marks, a chemical peel or a pigment-targeting treatment can help, and our comparison of hyperpigmentation versus melasma is useful if you are not sure what kind of discolouration you are dealing with. Our pigmentation treatment page covers the clinical options, and if enlarged pores came along for the ride, which happens often with acne-prone skin, our enlarged pores page addresses that too.

At-Home Care: What It Can and Cannot Do

At-home products have a real but limited role, and it is worth being clear-eyed about the ceiling. Topicals can fade flat marks and smooth very shallow texture. They cannot rebuild the collagen lost in a true atrophic scar, so a drugstore “scar” serum is not going to fill an ice pick scar no matter how long you use it.

Within that limit, a few ingredients genuinely earn their spot. Retinoids speed cell turnover and support collagen over months. Vitamin C helps with brightness and pigment. Alpha and beta hydroxy acids exfoliate and smooth. Silicone gel is the one with the most evidence for raised scars specifically. And sunscreen, again, does more than people think, because it protects fragile healing skin and keeps marks from darkening.

	At-home topicals	In-clinic treatments
Best at	Flat marks, mild texture, maintenance	True indented and raised scars
How fast	Weeks to months, subtle	Visible over a series of sessions
Cost	Lower upfront, ongoing	Higher upfront, fewer sessions
Downtime	None	Minimal to a week, depending
Realistic ceiling	Smoother, brighter, more even	Noticeably softened scars

My honest take is that topicals are a great foundation and a poor substitute. Use them, keep expectations sensible, and treat them as the supporting layer under whatever in-clinic plan actually addresses the scars.

Acne Scar Treatment and Skin Tone

Skin tone changes the safety math, and a good provider plans around it. Deeper skin has more active melanin, which means a higher chance of post-inflammatory hyperpigmentation if a treatment is too aggressive or the heat is poorly controlled. That does not put scar treatment out of reach for darker skin. It just means device choice and settings need to be more careful.

In practice, microneedling and RF microneedling tend to be safer starting points for deeper skin tones, because a lot of their action happens below the surface rather than by burning off the top layer. When lasers are used, non-ablative and longer-wavelength devices at conservative settings are generally the safer route, and a test patch is a reasonable ask. If you have deeper skin, the single most useful question to put to a clinic is how often they treat skin tones like yours and with which devices. The answer tells you a lot.

How Many Sessions and How Long Until I See Results?

Patience is genuinely part of the treatment here, because collagen does not rebuild overnight. Most resurfacing and needling treatments run as a series, and the real payoff shows up gradually.

A rough rule of thumb: you will often notice early change within a few weeks, but the collagen keeps remodeling for three to six months after your final session. So the photo that matters is the one taken a few months after you finish, not the day after.

Downtime, Risks and Safety

None of these treatments is risk-free, and a responsible clinic will walk you through the specifics for your skin rather than wave them away. Common, expected reactions include redness, mild swelling, pinpoint scabbing and a sunburned feeling for a day or several, depending on the treatment. These settle on their own.

The reactions worth watching for, and worth calling your provider about, include pigment changes that are not fading, signs of infection, or unusual prolonged swelling. The main risk that scales with skin tone is post-inflammatory hyperpigmentation, which is usually temporary but can be stubborn. Doing a treatment over active, inflamed acne is its own hazard, since it can spread bacteria and irritate already angry skin. The standard sequence is to get active breakouts under control first, often with a physician’s help, and then treat the scars. If you are still fighting breakouts, our guide to adult acne and how clinics treat it and our overview of hormonal acne treatments are good next reads.

The energy devices used for scar treatment, including lasers and RF systems, are regulated as medical devices in Canada. You can read more through Health Canada’s medical devices information. Regulation of the device is not the same as suitability for your skin, which is a separate judgment a trained provider makes.

What Does Acne Scar Treatment Cost?

Cost is hard to pin to a single number, because it depends on your scar types, how many areas are treated, which device is used and how many sessions you need. As a planning guide only, individual in-clinic sessions in the GTA commonly land somewhere in the low hundreds to several hundred dollars each, and a full plan that combines treatments adds up accordingly. Packages often bring the per-session price down compared with paying one at a time.

I would not treat any online number as a quote, including this one. The useful move is an assessment where someone looks at your actual scars, tells you which treatments make sense, and gives you a real plan with real pricing. That also stops you from paying for a treatment that was never going to help your particular scars, which is the most common way money gets wasted here.

How to Choose a Provider and What a Consultation Covers

Acne scar treatment rewards experience, maybe more than almost any other aesthetic treatment, because so much rides on correctly reading the scars and choosing among several tools. When you are weighing a clinic, it is fair to ask how often they treat scars like yours, which devices they use and why, whether they treat your skin tone regularly, and what a realistic outcome looks like for your case. A provider who promises perfectly smooth skin is a red flag. One who talks in terms of meaningful improvement over a series is being straight with you.

At Canada MedLaser, a skin-concerns consultation is complimentary and starts with mapping your scar types, since that is what determines everything after. Our acne scar treatment page outlines the in-clinic options we offer, including microneedling, RF microneedling with Morpheus8, fractional laser resurfacing and chemical peels, and where your situation calls for a procedure or prescription on the medical side, we will point you toward a physician rather than overreach. You can book a skin-concerns consultation at a Toronto or GTA clinic when you are ready, with no obligation to decide anything on the spot. If your interest is broader skin regeneration, our vampire facial with PRP write-up is a related read, since PRP is sometimes paired with microneedling.

Frequently Asked Questions About Acne Scar Treatment

What is the best treatment for acne scars?
There is no single best treatment, because it depends on your scar type. Ice pick scars respond to TCA CROSS or punch excision, boxcar and rolling scars to fractional laser, RF microneedling and subcision, and raised scars to steroid injections. Most people need a combination, which is why an assessment comes first.

Can acne scars be removed 100 percent?
Not completely. True textural scars can be softened a great deal, often to the point of being hard to notice in normal light, but no honest clinic promises total erasure. The flat marks people sometimes call scars do fade, which is a separate matter.

What is the fastest way to treat acne scars?
Fractional laser resurfacing often shows change in the fewest sessions, but it comes with more downtime, and it is not right for every scar type or skin tone. Fast and best are not always the same thing, so the choice still comes back to your scars.

Are acne scars permanent?
Indented and raised scars are permanent in that they will not vanish on their own, though treatment can improve them substantially. Flat brown or red marks are not permanent and usually fade over months.

How do I know what type of acne scars I have?
Look at your skin in side lighting and feel the surface. Deep narrow pits are ice pick, wider sharp-edged pits are boxcar, soft wavy depressions are rolling, and raised firm bumps are hypertrophic or keloid. Flat discolouration is a mark, not a scar. A professional can confirm the mix quickly.

Does microneedling work for acne scars?
Yes, for mild to moderate rolling and boxcar scars and general texture, usually over three to six sessions. It is less effective on deep ice pick scars on its own, and it is generally safe across skin tones.

Is Morpheus8 or microneedling better for acne scars?
RF microneedling like Morpheus8 reaches deeper and adds skin tightening, so it tends to suit deeper scars and mild laxity, while standard microneedling is a gentler option for shallower scars. The right pick depends on scar depth and your skin.

Does laser remove acne scars?
Laser resurfacing improves many boxcar and rolling scars and evens out tone, but it improves rather than removes them, and deeper skin tones need careful device and setting choices to avoid pigment problems.

What treats ice pick scars?
Ice pick scars respond best to TCA CROSS, which rebuilds them from the base, and to punch excision for the deepest ones. Surface resurfacing alone rarely reaches them.

What is subcision and which scars need it?
Subcision is a minor procedure that releases the fibrous bands tethering a rolling scar down, letting the surface lift. It is specifically for rolling scars and is often paired with collagen-building treatments afterward.

Will chemical peels get rid of acne scars?
Peels help with shallow texture and especially with dark marks, but they are a supporting treatment for true indented scars rather than a cure. They work best alongside needling or laser.

How long does it take to see results from acne scar treatment?
You may see early change within a few weeks, but collagen keeps remodeling for three to six months after your last session, so the fairest assessment comes a few months after a full series.

How many sessions will I need?
Most needling treatments run three to six sessions, RF microneedling three to four, and fractional laser one to three, spaced about four to six weeks apart. Your exact number depends on scar severity and type.

Can I treat acne scars while I still have active acne?
Generally no. Treating over active, inflamed acne can spread bacteria and irritate the skin, so the usual approach is to get breakouts under control first, often with a physician, then treat the scars.

Are acne scar treatments safe for darker skin tones?
Yes, with the right choices. Microneedling and RF microneedling are often safer starting points for deeper skin, and when lasers are used, conservative non-ablative settings reduce the risk of post-inflammatory hyperpigmentation. Ask how often a clinic treats your skin tone.

How do I get rid of the dark marks left after acne?
Those marks are usually post-inflammatory hyperpigmentation and fade over months. Daily sunscreen is the biggest lever, with retinoids, vitamin C, azelaic acid and sometimes a chemical peel speeding things along.

What is the difference between an acne scar and a dark mark?
A scar is a change in texture you can see or feel, like a pit or a raised bump. A dark or red mark is flat discolouration. Scars need treatment to improve, while most marks fade on their own.

Can at-home products fix acne scars?
They can fade marks and smooth very shallow texture, but they cannot rebuild the collagen lost in a true atrophic scar. Use them as a foundation, not a replacement for in-clinic treatment of real scars.

Does Canada MedLaser treat acne scars?
Yes. We offer in-clinic treatments including microneedling, RF microneedling with Morpheus8, fractional laser resurfacing and chemical peels, and we start with a complimentary consultation to map your scar types. For procedures or prescriptions on the medical side, we point you toward a physician.

Expert Insight

The people who get the most out of acne scar treatment tend to do two things. They get their scars properly assessed before spending a dollar, because the wrong treatment on the wrong scar type is the single biggest waste of money in this field. And they commit to a series and a timeline rather than expecting one session to do it, since collagen simply does not work that fast.

The ones who end up frustrated usually chased a quick fix, bought a cream expecting it to fill a pit, or picked a treatment based on a friend’s results without checking whether their scars were even the same type.

Match the treatment to the scar, commit to the full series, and judge the result a few months out rather than the next morning. That mindset gets better outcomes than any single device.

Conclusion

Acne scars are treatable, often more than people expect, but the path runs through the right diagnosis rather than the trendiest device. Indented scars need collagen-building and resurfacing treatments matched to their shape, raised scars need the opposite approach, and the flat marks that get mistaken for scars usually fade with time and good basics. For most people the answer is a combination, delivered over a series, with results judged a few months out.

If you are not sure what you are looking at, that is the normal starting point, not a reason to wait. A consultation sorts your scar types, rules out treatments that will not help, and gives you a realistic plan for your skin. Bring your questions, and let a qualified professional build it from there.

This article is general education and not a substitute for personalized medical advice. Acne scar treatments, their risks and their suitability depend on your scar type, skin tone and medical history, and should be assessed by a qualified professional in person. Results vary from person to person and are not guaranteed, and no treatment removes acne scars completely. Anyone who is pregnant, breastfeeding or managing a skin or medical condition should consult a physician before starting treatment.
