Thinking about CO2 Laser Resurfacing for your acne scars? You’re definitely not alone. This treatment has become popular for folks hoping to smooth out uneven skin and reduce the look of old scars. But it’s not for everyone, and there are a few things you should know before booking that appointment. Here’s what you can expect, how to get ready, and what kind of results people usually see—plus a few things you might not have thought about.
Key Takeaways
CO2 Laser Resurfacing can help improve the texture and appearance of acne scars, but it won’t erase them completely.
The treatment works best for certain types of scars and lighter skin tones; those with darker skin or melasma may need to consider other options.
Most people need to avoid sun exposure and certain medications before the procedure, and some may need antiviral medication to prevent complications.
Recovery can take up to two weeks, with redness, swelling, and peeling being common; following aftercare instructions is key for the best results.
A single session can cost around $2,500, but some people need multiple treatments—financing options are often available.
How CO2 Laser Resurfacing Improves Acne Scars
CO2 laser resurfacing has been transforming the way acne scars are managed by harnessing the power of high-energy light to help skin heal itself. The process stimulates natural repair, encouraging new, healthier skin to take the place of damaged, scarred tissue. Let's break down how it actually works, which scars benefit most, and what you can realistically expect.
Mechanism of Action and Collagen Stimulation
CO2 laser resurfacing uses pulses of focused light to remove precise layers of damaged skin. The most advanced versions of these devices, like fractional CO2 lasers, target the skin in microscopic zones, allowing healthy skin to help with faster healing. When the top layer is vaporized, the body ramps up collagen production as it repairs. This boost in collagen is what helps soften and smooth out scar tissue over time.
Here's what happens in a typical treatment:
Laser energy is applied, creating controlled micro-injuries.
Old, scarred skin is removed in tiny columns, leaving surrounding skin untouched for faster recovery.
Your body starts making fresh collagen and new skin cells.
Most people notice their skin gradually looking and feeling smoother, but it isn't a quick fix. The real improvements keep rolling in over months as collagen builds up.
Types of Scars Best Treated
Not every acne scar will respond the same way. CO2 laser resurfacing excels at improving certain types:
Atrophic scars (boxcar and rolling scars)
Some icepick scars, especially if they're shallow
Scars with a rough texture or raised edges
Discoloration due to old acne spots
Sometimes, deep icepick scars or extensive thick (hypertrophic/keloid) scars need a different approach. If you're unsure what kind you have, a good dermatologist will help you sort it out. For a quick science-based explanation, see how CO2 laser resurfacing targets problem skin.
Expected Improvements and Limitations
While CO2 lasers do an impressive job, there are limits. Most people can expect:
Noticeable softening and smoothing of indented scars
More even skin tone where old marks have faded
Fewer visible signs of past breakouts
But it's not magic. Some scars, especially very deep or complex types, may only partially improve. The texture and appearance look better, but scars rarely vanish entirely.
Give your skin time—results build up slowly, especially as collagen rebuilds. Expect to see initial changes in about 1–2 months after your first session, with best results after a series of treatments where needed.
To sum up: CO2 laser resurfacing can dramatically upgrade the look and feel of acne-scarred skin, but it's not instant or perfect. The biggest improvements happen over time, with realistic expectations and the right aftercare.
Who Is a Candidate for CO2 Laser Resurfacing
CO2 fractional laser resurfacing can do a lot for acne scars, but it's not for everyone. It's important to know if this treatment matches your skin type, current skin conditions, and overall goals.
Assessing Skin Type and Tone
People with lighter skin tones generally see the best and safest results. Darker skin tones can face higher risks of hyperpigmentation and discoloration after treatment.
A careful consultation will help determine if your skin’s tone and texture make you a good fit. CO2 laser resurfacing is particularly well-suited for folks with skin that’s not too oily, not super lax, and doesn’t tend to scar after small injuries—these qualities often predict fewer complications, according to CO2 laser facial resurfacing guidance.
Preexisting Conditions to Consider
If you have certain health or skin issues, you’ll want to talk these over with your provider:
Active acne breakouts or infections (like cold sores or herpes simplex)
History of keloids or bad scarring
Autoimmune conditions or medications that slow healing
Recent use of Accutane (isotretinoin)
Pregnancy or breastfeeding
It’s smart to be upfront about your full health history before booking any laser session—this can save you from uncomfortable side effects and wasted time.
Alternatives for Darker and Melasma-Prone Skin
Because CO2 fractional lasers can sometimes lead to stubborn dark patches—especially in those with naturally deeper skin color or melasma—you might want to ask about:
Picosecond lasers (non-ablative options that specifically target pigment)
Erbium laser resurfacing, which is gentler for darker skin
Chemical peels or microneedling as lower-risk options
A personalized approach may mean skipping CO2 and exploring these alternatives for better safety and lasting results.
If you find yourself unsure, bring up all your skin concerns and history during the consult—no detail is too minor when it comes to your face.
Preparing for Your CO2 Laser Resurfacing Session
Getting the best results from a CO2 fractional laser means having a plan before you even step into the office. Proper preparation will set you up for a smoother experience and recovery. Let’s run through what you should expect and do in the days leading up to your appointment.
Pre-Treatment Skin Care and Sun Protection
It's really important to take care of your skin before your treatment. Here’s how to get your skin ready:
Stop tanning and avoid direct sun for at least two weeks before your session.
If you do go outside, use a broad-spectrum SPF 30+ sunscreen with zinc oxide or titanium dioxide every day.
Use a gentle cleanser—skip anything with strong acids or exfoliants for at least a week before.
Your skin will thank you for being extra cautious. Less sun and irritation before your laser means less risk for problems after.
Medications to Avoid Before Treatment
Certain medications can make your skin more sensitive, so you'll want to keep these points in mind:
Tell your provider about ALL your medicines, including over-the-counter ones.
Avoid antibiotics that cause sun sensitivity (like doxycycline or minocycline) for at least 3 days before laser day.
Cut out blood thinners, fish oil, or anything that could cause bleeding or bruising, unless your doctor says otherwise.
Here’s a quick table to help you keep track:
Antiviral and Allergy Considerations
If you’ve ever had cold sores or herpes around your mouth, don’t forget this step! The laser can wake up old viruses.
Let your provider know if you get cold sores or have had shingles. They might prescribe a preventative antiviral (like valacyclovir or acyclovir), which usually starts two days before your session and runs for several days after.
If you have a history of allergies or skin reactions, share this with your provider as well, so they can recommend ways to prevent a flare-up.
Preparing for your CO2 laser isn't just about marking the date on your calendar. Good habits and honest talks with your provider can make the whole process a lot more comfortable and less stressful. You want to show up feeling ready—not rushing to fix something last-minute.
What Happens During the CO2 Laser Resurfacing Procedure
Alright, so you've decided to go for CO2 laser resurfacing to treat your acne scars. It's natural to have questions about how the whole thing unfolds, from what you'll feel during the actual treatment to what happens once it's done. Here’s what you can really expect on the day of your procedure.
Anesthesia and Comfort Measures
For most people, numbing cream is applied to the treatment area about an hour before the session starts. Sometimes, your provider might also use local injections or, in rare cases, sedation if they're covering a larger area or you feel super anxious. These steps help make the experience pretty manageable—even though some warmth or a tingling sensation is normal. If you're anxious about pain, don't hesitate to bring it up ahead of time so your team can plan with you.
Topical numbing cream is standard for comfort
Local anesthesia may be added for bigger or sensitive zones
Some clinics offer stress-relief options like cooling fans or distraction tools
Most patients describe the feeling like a hot prickly sensation or a strong sunburn, but it usually eases up quickly once the session ends.
Treatment Duration and Areas Treated
The amount of time you’ll be in the chair depends a lot on how much skin is being treated. The entire face typically takes 30 to 60 minutes. If you’re just doing cheeks or the forehead, it’s much quicker—you could be out in under 20 minutes.
The laser works by making tiny, focused columns in the skin, targeting damaged cells without disturbing the skin around them. This approach—called fractional CO₂ resurfacing—lets your skin heal faster, using healthy cells as a base. If you want a bit more info about how fractional CO2 works, you can read about how these treatments penetrate and heal from within while keeping some of the outer skin layer intact on this summary of fractional CO2 laser methods.
Immediate Post-Procedure Care
Right after the session, your skin will usually look—and feel—red, raw, and warm. Some clinics apply a soothing serum or even your own processed plasma to kickstart healing. If your provider recommends it, you'll start a simple skincare routine before you head home:
Apply a gentle, hydrating barrier cream or ointment to protect new skin
Avoid touching or picking at the treated area
Use cold compresses if you feel discomfort
Skip exercise and stay out of direct sun for a few days
Most clinics will review detailed aftercare, but the first 24 hours are mainly about keeping your skin cool and covered. The full healing routine starts right away, with instructions specific to your procedure depth and your provider’s preferences.
The initial few hours and days are important for recovery. The better you stick to these steps, the quicker you’ll see results, and the less likely you are to experience problems.
Recovery and Aftercare for Optimal Results
After a CO₂ fractional laser session, real recovery starts the moment you leave the clinic. Your skin will need some TLC to heal well — and how you treat it in these first weeks truly shapes your results. Clinics like Evercare Wellness & Aesthetics usually give you a detailed recovery plan, but here's what you can expect daily and some must-follows for smoother healing:
Managing Redness and Swelling
Right away, you’ll notice your skin looks red and may feel warm — almost like a strong sunburn. Swelling is common and might hang around for a few days. Here’s what can help:
Cool down with an ice pack for 15 minutes, as suggested by your nurse, to manage swelling and increase comfort (use an ice pack on the treated area).
Sleep with your head slightly elevated for the first couple nights to keep swelling to a minimum.
Avoid hot environments — skip saunas and steamy showers for now.
The first few days after your procedure are when your skin is most sensitive, so gentle care really pays off.
Cleansing and Moisturizing Tips
A clean, hydrated face is your friend. At this point, forget any rough scrubs or strong products. Instead, stick to this routine:
Wash with a mild cleanser (never anything scented or for acne).
Pat your skin dry — do not rub.
Apply a rich ointment or plain moisturizer (like Aquaphor) to prevent scabs.
Repeat this process 3–5 times daily, or as your provider recommends.
A simple table to track your daily skin care during the first week:
Makeup and Sun Protection Post-Treatment
After about 7–10 days, you might feel ready for makeup, but only certain types are safe:
Green-tinted or mineral-based makeup helps camouflage lingering redness.
Oil-free products are less likely to clog pores or cause irritation.
Always use broad-spectrum SPF 30 or higher before any sun exposure.
Remember, your skin will be extra sensitive to sun for weeks. Hats and shade are your best backup plans if you step outside.
The best results come from careful aftercare and patience during recovery. Evercare Wellness & Aesthetics encourages clients to follow every aftercare instruction for smoother healing and better scar outcomes. If you’re ever unsure or your skin isn’t healing as expected, reach out for advice. Protecting your investment in time and comfort will help your new skin look its best.
Potential Risks and Side Effects of CO2 Laser Resurfacing
Fractional CO2 laser resurfacing isn’t just another quick fix for acne scars—it’s a treatment with real risks and side effects that people should know about before booking an appointment. Most side effects are temporary, but some can last longer or even be permanent. Let’s get into what you might face.
Scarring and Infection
Actual scarring isn’t common, but it’s definitely possible, especially if the area is infected or you don’t follow care instructions.
Infections can sneak up, often from bacteria or even cold sores (herpes), especially if you’re already prone.
Phases of healing might look worse before they look better: oozing, yellow crusts, or unexpected pain could be signs something’s off.
Quick prevention checklist:
Keep the treated area clean (but don’t overdo it).
Avoid touching, scratching, or picking at healing skin.
If you have a history of cold sores, ask for an antiviral prescription ahead of time.
While CO2 lasers do a great job resurfacing skin, they rely on your body to finish healing properly—so those aftercare steps are actually a big deal.
Hyperpigmentation and Skin Sensitivity
The risk of dark spots (hyperpigmentation) jumps if you have medium-to-dark skin tones or a history of melasma.
Treated skin will react more to the sun—think raw, new skin—so skipping sunscreen is a bad move.
Temporary redness and sensitivity can last anywhere from a few days to several weeks, depending on how deep the treatment went.
Here’s a look at typical skin responses and timelines:
How to Minimize Complications
Diligent post-laser care cuts your risk of problems a lot.
Use only the gentle cleansers and ointments your provider recommends—no exfoliants or harsh products.
Stay out of the sun; when you can’t, make zinc/titanium-based sunscreen part of your routine.
If redness, swelling, or pain get worse instead of better, it’s worth calling the office sooner rather than later.
While plenty of people see good results from fractional CO2, it’s important to be realistic—not every scar disappears, and some side effects are just part of the process. But knowing about them ahead of time helps you go into treatment prepared and less stressed out.
Expected Results: CO2 Laser Resurfacing Before and After
CO2 fractional laser resurfacing can make a big difference for people with stubborn acne scars, but what exactly can you expect once it’s over? Let’s get real about the results, using examples and some honest perspective.
Visible Improvements in Texture and Tone
One of the main reasons folks choose CO2 laser resurfacing is for changes in skin texture and evenness. Most people notice their indented scars look shallower and their skin feels smoother overall. Bumpy areas can blend in more, while dark spots from scarring often fade after healing. Still, CO2 lasers can’t erase scars completely—they just make them less obvious. Deep scars or widespread roughness will usually need more than one session. Smaller pores and healthier-looking skin are common wins.
Smoother, more unified skin surface
Reduced look of deep or boxcar scars
Pores may seem tighter
Old red or brown marks can fade
People often report feeling more comfortable without makeup after a few weeks, though minor redness or swelling can stick around for a bit.
Examples from Real Patient Cases
Patient stories and before-and-after evidence help set expectations for anyone considering this route. If you peek at some CO2 laser resurfacing before and after photos, there are examples of people who:
Had 3-5 sessions and saw their scars blend into surrounding skin
Noticed a big change in color, with scar pigmentation evening out
Observed overall smoother skin even when scars didn’t disappear completely
Occasionally, saw dramatic results after just one session, but most saw gradual improvements
How Many Sessions Are Needed
It’s pretty common to wonder how many appointments you’ll need before you’re happy with the results. The truth is, it varies a lot based on scar type, severity, and skin’s natural healing. Most folks need more than one session—fewer if scars are mild, more for deeper issues. Some need maintenance sessions every year or two to keep up their results.
Here’s a quick look at what you might expect:
Improvement builds up after each round of healing, so patience is key while your skin does its repair work.
Remember, not everyone gets the same results, but with the right plan, most people see positive changes that help boost their confidence.
Understanding the Cost and Value of CO2 Laser Resurfacing
CO₂ laser resurfacing can be a big step for anyone looking to treat acne scars. Most people want to know whether it's worth it—especially when the costs aren't exactly pocket change.
Typical Pricing and Financing Options
The cost of CO₂ laser resurfacing often lands between $1,000 and $3,000 per treatment session, with an average full-face treatment running about $2,500. A few factors (like geography and provider experience) can shift those numbers up or down. Sometimes just one session delivers good results, but deeper or more severe scarring may mean you’ll need a second round. Many clinics offer financing, so payment installments are possible if you don’t want to pay the whole amount up front. Some places, such as Evercare Wellness & Aesthetics, mention accepting a mix of payment methods and even special credit providers made for medical procedures.
*Estimates – actual charges depend on local rates and provider policies.
Factors Influencing Cost
What’s included in each bill varies. Here are a few things that play into the final price:
Size and number of areas treated (face, neck, chest, etc.)
Number of sessions or passes needed for your specific scars
Experience and credentials of the provider
Practice location (metropolitan clinics often charge more)
Pre- and post-care products or consultations bundled in
It’s a good idea to get a clear written quote for your personalized treatment and ask about all included services, so you don’t run into hidden fees later on.
Comparing to Other Acne Scar Treatments
Is CO₂ resurfacing really worth the investment? Here’s how it stacks up in value against some other options:
Microneedling: Generally $200–$700 per session. Less downtime, milder results, and usually more sessions are needed.
Chemical Peels: Can range from $150–$600 per session. Suitable for light scarring, repeated treatments often required for improvements.
Dermal Fillers: Price varies by filler type, but can range from $600–$1200 per syringe with results lasting 6-18 months.
CO₂ Fractional Laser: Requires more upfront dollars, but one session may outperform several milder treatments and the smoothing effects stick around for years.
Some clinics add extra value—like customized post-treatment care, ongoing support, or free follow-up visits. When weighing the price tag, be sure to factor in both the power of the results and the potential longevity.
You want an effective solution that fits your budget, but also delivers real changes you can see and feel.

Conclusion
So, is CO₂ fractional laser the right move for your acne scars? It really depends on your skin, your goals, and how much downtime you’re willing to handle. Some people see big changes after just one session, while others need a few rounds to get the results they want. The treatment isn’t magic—it can make scars look a lot better, but it probably won’t erase them completely. There’s also the cost to think about, which can add up, especially if you need more than one session. Recovery can be a bit of a process, too, with redness and peeling for a week or two. If you have darker skin, you’ll want to talk with your provider about the risks of hyperpigmentation and whether another type of laser might be safer. At the end of the day, it’s a personal decision. If you’re curious, book a consultation with a pro who can walk you through your options and help you figure out what’s best for your skin. And if you go for it, just remember to follow all the aftercare instructions—they really do make a difference in how you heal and what your results look like.
