Will CoolPeel Take My Acne Scars Off? #

If you have acne scars, you may be wondering:

Will CoolPeel take my acne scars off?

The short answer is:

CoolPeel can improve the appearance of certain acne scars, but it usually will not completely erase them.

CoolPeel is a fractional CO2 laser treatment that can improve skin texture and stimulate remodeling. But acne scars aren’t all the same.

Some are shallow.

Some are deep.

Some are narrow.

And some are physically tethered underneath the skin.

That means one laser treatment isn’t automatically the answer for every acne scar.

The first question shouldn’t be:

“Which laser should I use?”

It should be:

“What type of acne scars do I have?”

How Does CoolPeel Help Acne Scars? #

Acne scars develop when inflammation from acne damages the skin and interferes with normal collagen formation.

With atrophic acne scars, the result is a depression or indentation in the skin.

CoolPeel uses fractional CO2 energy to create microscopic treatment zones in the skin.

This controlled injury initiates a wound-healing response and collagen remodeling.

Over time, this may help:

• Smooth uneven texture
• Soften the edges of shallow scars
• Improve overall skin quality
• Reduce the contrast between scars and surrounding skin
• Make pores appear more refined
• Improve some superficial textural irregularities

The goal isn’t necessarily to make every scar disappear.

It’s to make the overall skin surface smoother and the scars less noticeable.

Can CO2 Laser Improve Acne Scars? #

Yes.

Fractional CO2 laser has substantial clinical evidence supporting its use for atrophic acne scars.

A 2026 systematic review and meta-analysis involving 17 studies and more than 1,000 patients found that fractional CO2 laser and needling-based treatments both produced meaningful improvement in atrophic acne scars. The researchers emphasized that outcomes depend on factors including scar type, skin type, and complication risk.

However, most research evaluates fractional CO2 resurfacing broadly.

That is important because CoolPeel represents a generally lighter, more superficial approach to fractional CO2 treatment.

You shouldn’t assume that research involving deeper fractional CO2 resurfacing will produce identical results with a light CoolPeel treatment.

Will CoolPeel Completely Remove Acne Scars? #

Probably not.

“Remove” creates an unrealistic expectation.

Acne scars represent structural changes in the skin.

Once that structure has changed, treatment generally aims to improve the scar rather than return the skin to a completely scar-free state.

A realistic goal may be:

Smoother texture.

Softer scar edges.

Less visible indentations.

Better collagen support.

More even-looking skin.

How much improvement you can achieve depends heavily on your scar pattern.

What Type of Acne Scars Do You Have? #

Atrophic acne scars are generally divided into three major categories:

Rolling Scars #

Rolling scars create broad, shallow depressions that give the skin a wavy appearance.

Some rolling scars are caused by fibrous attachments underneath the skin that pull the surface downward.

These are often called tethered scars.

Boxcar Scars #

Boxcar scars are wider depressions with more defined edges.

They may be:

• Shallow
• Moderate
• Deep

The depth of the boxcar scar can significantly influence treatment selection.

Ice-Pick Scars #

Ice-pick scars are:

• Narrow
• Deep
• V-shaped

They can extend deeply into the dermis.

Because of their narrow and deep structure, they may be more difficult to improve with resurfacing alone.

Research reviews confirm that these scar types differ structurally, which is one reason acne-scar treatment needs to be individualized.

Which Acne Scars Respond Best to CO2 Laser? #

Historically, fractional CO2 studies have shown particularly useful improvement in rolling and superficial boxcar scars, while deep ice-pick scars tend to be more challenging.

A systematic review of energy-based acne-scar treatments found that rolling and superficial boxcar scars generally responded better to fractional CO2 resurfacing than ice-pick scars.

But this does not mean every rolling scar should automatically be treated with laser.

If a rolling scar is significantly tethered underneath the skin, resurfacing the top of the scar may not address the underlying attachment.

That’s where treatments such as subcision may become important.

Is CoolPeel Good for Shallow Acne Scars? #

This is where CoolPeel may make more sense.

If you have:

• Mild textural irregularities
• Shallow scars
• Enlarged-looking pores
• Uneven texture
• Early acne scarring

CoolPeel may help improve the overall surface of the skin.

Because CoolPeel is generally a lighter fractional CO2 approach, the improvement may also be more gradual and subtle than with deeper resurfacing.

For someone who wants manageable downtime, that trade-off may be worthwhile.

Is CoolPeel Enough for Deep Acne Scars? #

Sometimes it isn’t.

This is one of the most important things to understand before spending money on repeated laser treatments.

If you have significant:

• Deep boxcar scars
• Ice-pick scars
• Tethered rolling scars
• Mixed severe acne scars

a superficial CoolPeel alone may not create the improvement you’re hoping for.

That doesn’t mean CO2 laser isn’t useful.

It may mean you need:

• A deeper fractional CO2 treatment
• Subcision
• Microneedling
• RF microneedling
• Another scar-specific treatment
• A carefully staged combination approach

The treatment has to match the scar.

What Are Tethered Acne Scars? #

Some depressed scars are held down by fibrous bands underneath the skin.

Think about pulling the underside of a sheet downward with your finger.

You can smooth the top of the sheet repeatedly, but as long as you’re still pulling from underneath, the depression remains.

A tethered acne scar can behave similarly.

This is why resurfacing alone may have limitations.

Can CoolPeel Release Tethered Acne Scars? #

CoolPeel resurfaces and remodels the skin.

It does not mechanically release a deeply tethered scar in the same way that subcision is designed to address underlying fibrous attachments.

Subcision involves treating the structural tether beneath selected depressed scars.

Research reviews recognize subcision as an established treatment option for atrophic acne scars, particularly where tethering contributes to the depression.

For the right patient, releasing the tether first and then improving the skin surface may make more sense than repeatedly resurfacing a scar that remains anchored underneath.

What About Boxcar Acne Scars? #

Boxcar scars can respond well to resurfacing, but their depth matters.

A shallow boxcar scar may respond much differently than a deep, sharply defined scar.

For superficial boxcar scars, fractional resurfacing may help soften the edges and make the transition between the scar and surrounding skin less noticeable.

For deeper boxcar scars, a stronger or combined approach may be needed.

What About Ice-Pick Scars? #

Ice-pick scars are particularly challenging because they are narrow but extend relatively deeply.

Research has historically found them less responsive to fractional CO2 resurfacing than rolling and superficial boxcar scars.

That doesn’t mean CO2 has no role.

It means resurfacing alone may not be the most efficient strategy.

A patient with predominantly ice-pick scars may require a different treatment plan than someone with broad, shallow rolling scars.

CoolPeel vs Deeper CO2 for Acne Scars #

This distinction is very important.

CoolPeel is CO2 laser.

But not every CO2 treatment is performed at the same intensity.

CoolPeel #

Generally emphasizes:

• Lighter fractional resurfacing
• More manageable downtime
• Surface texture
• Fine lines
• Pores
• Mild photoaging
• Shallow textural irregularities

Deeper Fractional CO2 #

May be more appropriate when treating:

• More established acne scars
• Deeper boxcar scars
• More significant texture changes
• Greater collagen-remodeling needs

The trade-off is generally more recovery and potentially greater risk.

So if acne scars are your primary concern, simply asking whether a clinic has a CO2 laser isn’t enough.

You need to know whether the treatment plan is appropriate for your scars.

Is More Aggressive CO2 Always Better for Acne Scars? #

No.

Going deeper creates more tissue injury.

That may be useful for certain scars, but it can also increase:

• Downtime
• Redness
• Swelling
• Post-inflammatory hyperpigmentation
• Infection risk
• Delayed healing
• Other complications

A 2026 meta-analysis found fractional CO2 effective for atrophic acne scars but also found a higher risk of post-inflammatory hyperpigmentation compared with standard microneedling.

That risk is particularly important when treating patients prone to pigmentation changes.

The goal isn’t to use the strongest treatment possible.

The goal is enough treatment to create improvement without creating unnecessary risk.

CoolPeel vs Microneedling for Acne Scars #

Both can improve acne scars, but they work differently.

Microneedling #

Uses controlled mechanical microinjury to stimulate collagen remodeling.

It may be useful for:

• Mild-to-moderate atrophic scars
• Texture
• Pores
• Collagen induction

CoolPeel #

Uses fractional CO2 energy to combine resurfacing with a wound-healing response.

It may be useful for:

• Texture
• Shallow scars
• Fine lines
• Pores
• Photoaging
• Surface irregularities

Recent evidence suggests both fractional CO2 and needling-based treatments can improve atrophic acne scars, without one modality being universally superior for every patient.

What About RF Microneedling? #

RF microneedling delivers radiofrequency energy into the skin through needles.

This creates a different type and depth of collagen-remodeling response.

It may be particularly useful when we’re trying to address:

• Acne scars
• Texture
• Pores
• Deeper collagen remodeling
• Mild skin laxity

Recent systematic reviews comparing fractional CO2 with RF microneedling show that both can improve atrophic acne scars, while their risk profiles and responses may differ according to scar type and skin characteristics.

This is another reason we don’t believe everyone with acne scars needs the same procedure.

Can You Combine Subcision With CO2 Laser? #

For appropriately selected scars, a staged combination approach may make sense.

For example, if a scar is tethered:

First problem ? the scar is attached underneath

Second problem ? the surface texture is irregular

One treatment may address the tether.

Another may address the surface and collagen remodeling.

That is a much more logical approach than expecting one treatment to solve two different structural problems.

Combination treatment should be planned carefully rather than simply stacking procedures because “more is better.”

How Many CoolPeel Treatments Will I Need for Acne Scars? #

There isn’t one number.

Some patients may notice improvement after one treatment.

Others may benefit from a series.

But if you’re repeatedly performing superficial CoolPeel and your deeper scars aren’t changing, the answer isn’t automatically to keep doing more CoolPeel.

The treatment plan may need to change.

You may need:

• Greater resurfacing intensity
• A different technology
• Subcision
• Scar-specific treatment
• A combination approach

More sessions don’t automatically mean better results.

When Will I See Improvement in My Acne Scars? #

Surface texture may begin looking smoother after the initial healing period.

Collagen remodeling takes longer.

You may continue seeing changes over the following weeks and months as the skin remodels.

This is why acne-scar treatments shouldn’t be judged seven days after the procedure.

Your skin may be finished peeling long before it is finished remodeling.

Will My Acne Scars Ever Completely Disappear? #

Complete removal shouldn’t be promised.

Even with an excellent treatment plan, some scars may remain visible.

A more realistic goal is to make scars:

• Shallower
• Softer
• Smoother
• Less shadowed
• Less noticeable in different lighting

For someone with significant scarring, even partial improvement can create a meaningful change in overall skin texture.

But realistic expectations matter.

Why Do Acne Scars Look Worse in Certain Lighting? #

Indented acne scars create shadows.

That’s why they may look relatively mild in soft frontal lighting but suddenly appear much deeper under:

• Overhead lighting
• Side lighting
• Bright sunlight

When treatment softens the depth or edges of a scar, it may reduce those shadows.

This is why standardized before-and-after photography is valuable when evaluating acne-scar improvement.

What If I Still Have Active Acne? #

Active acne should also be addressed.

Treating scars while someone continues developing inflammatory acne can become a cycle:

Treat old scars ? develop new acne ? create new scars.

Sometimes controlling the acne first is the most important part of the scar treatment plan.

Then we can focus on repairing what remains.

Is CoolPeel Safe for Darker Skin With Acne Scars? #

Fractional CO2 requires careful consideration in more melanin-rich skin because of the risk of post-inflammatory hyperpigmentation (PIH).

A recent meta-analysis found a higher PIH risk with fractional CO2 compared with standard microneedling.

That doesn’t automatically mean someone with darker skin cannot receive CO2 resurfacing.

It means treatment selection should consider:

• Skin type
• History of PIH
• Scar type
• Treatment intensity
• Recent sun exposure
• Aftercare
• Other available treatment options

Sometimes microneedling or RF microneedling may be a more appropriate starting point.

What Is the Best Treatment for Acne Scars? #

There isn’t one.

The best acne-scar treatment depends on the scar.

A simplified way to think about it is:

Shallow texture and superficial scars ? resurfacing may help

Tethered rolling scars ? consider whether the tether needs to be released

Deeper boxcar scars ? may need stronger resurfacing or combination treatment

Deep ice-pick scars ? may need a scar-specific approach

Mixed scars ? often require a combination strategy

This is why acne-scar treatment should begin with an assessment rather than simply purchasing a package of laser sessions.

So, Will CoolPeel Take Your Acne Scars Off? #

CoolPeel can improve certain acne scars, but it usually won’t completely remove them.

It may be particularly useful for:

• Mild acne scarring
• Shallow textural irregularities
• Superficial scars
• Enlarged-looking pores
• Overall uneven texture

But deeper, tethered, or more complex acne scars may require a different approach.

Fractional CO2 has good evidence for improving atrophic acne scars, but research also shows that outcomes vary according to scar type and treatment method.

The most important question isn’t:

“Will CoolPeel erase my scars?”

It’s:

“What kind of scars do I have, and what treatment actually addresses them?”

A Skin-Forward Approach to Acne Scars at AIVI Aesthetics #

At AIVI Aesthetics, we don’t believe every acne scar should be treated with the same laser.

Before recommending treatment, we look at:

• Scar type
• Scar depth
• Tethering
• Overall skin texture
• Pore appearance
• Pigmentation
• Skin type
• History of post-inflammatory hyperpigmentation
• Active acne
• Desired downtime

Then we build the treatment around what we actually see.

Depending on your scars, that may include CoolPeel, deeper Tetra Pro CO2 resurfacing, SkinPen microneedling, Vivace RF microneedling, subcision, PRF, or a carefully planned combination approach.

If the scar is tethered, we don’t want to keep resurfacing the top without addressing what’s pulling it down.

If the scar is superficial, we don’t necessarily need the most aggressive treatment available.

The treatment has to match the scar.

The goal isn’t perfect, poreless, filter-like skin.

It’s healthier, smoother, more even-looking skin with scars that are less noticeable—while keeping your results natural.
