Acne Scars That Peels and Creams Haven’t Touched. CO2 Laser Treatment Goes Deeper.
Acne scars sit in the dermis, the deeper structural layer of the skin. Topical products work above it. Even most light-to-medium peels reach only the upper portion of it. CO2 laser treatment is one of the few clinical options that actually penetrates to the depth where acne scarring lives and triggers the kind of collagen remodelling that makes a visible, lasting difference.
At Beauish Studio in DHA Karachi, CO2 laser treatment is performed using fractional technology with settings calibrated to your skin type, scar depth, and tone. Every session is assessed individually because not all acne scars or all skin types respond to the same protocol.
What Is CO2 Laser Treatment?
CO2 laser treatment is an ablative laser resurfacing procedure. The laser emits an infrared beam at a specific wavelength that is absorbed by the water molecules in the skin cells. When those cells absorb the laser energy, they are precisely vaporised, removing damaged tissue and triggering an immediate healing response in the skin beneath.
As the skin heals, it builds new collagen and elastin. The surface renews with fresher, smoother skin. Scar tissue that was previously raised, indented, or textured gradually remodels into a more even surface. This is not a surface-level treatment. It works in the actual structural layer where acne scars are formed.
The version most commonly used today is fractional CO2 laser, which delivers the laser energy in a grid of microscopic columns rather than treating the entire skin surface at once. Columns of treated tissue are surrounded by untreated healthy skin, which accelerates healing, reduces downtime significantly compared to older fully-ablative methods, and makes the treatment safer for a broader range of skin tones.
What Skin Concerns Does CO2 Laser Treatment Address?
CO2 laser treatment is primarily known for acne scars but its reach goes further. It effectively addresses:
- Acne scars including rolling scars, boxcar scars, and shallow ice-pick scars
- Uneven skin texture and rough surface irregularities
- Fine lines and wrinkles particularly around the eyes and mouth
- Skin laxity through deep collagen stimulation that firms the overall texture
- Sun damage and hyperpigmentation where the damaged surface layer is removed and renewed
- Enlarged pores where collagen remodelling tightens the pore structure
- Surgical or trauma scars that have settled and are being addressed for cosmetic improvement
- Stretch marks in some cases, particularly newer ones with more active tissue
The depth and intensity of the CO2 laser protocol is adjusted based on what is being treated. Acne scar resurfacing is among the most intensive applications. Pigmentation and texture concerns are treated at a lighter setting with shorter downtime.
Who Is CO2 Laser Treatment Right For?
CO2 laser treatment suits people with established acne scarring who have tried lighter treatments and want more significant improvement. Specifically:
- Adults with moderate to severe acne scarring across the cheeks, temples, or forehead
- People dealing with uneven, bumpy skin texture that remains after acne has cleared
- Those who have completed a course of chemical peels and want to take results further
- People in their mid-20s and above dealing with post-acne changes that have been present for more than a year
- Anyone with sun damage, fine lines, and texture concerns looking for more advanced resurfacing
Important considerations for Pakistani skin tones: CO2 laser carries a meaningful risk of post-inflammatory hyperpigmentation on medium to deep skin tones if not performed with proper settings and preparation. This does not mean it cannot be done on darker skin. It means it requires a provider who genuinely understands how to calibrate the laser for South Asian skin and who takes pre-treatment and post-treatment protocols seriously.
At Beauish Studio, skin tone is assessed in detail before CO2 laser treatment is recommended or scheduled. Pre-treatment preparation to reduce PIH risk is part of the standard process.
People who are not currently suitable candidates include those with active acne, recent sun exposure, open skin conditions in the treatment area, those on certain medications like isotretinoin within the past six months, pregnant women, and those with a history of keloid scarring.
What Are the Benefits of CO2 Laser Treatment for Acne Scars?
- Deep collagen remodelling reaches the dermal layer where acne scarring structurally lives
- Visible scar reduction across rolling, boxcar, and surface-level ice-pick scars
- Skin texture improvement produces a smoother, more even surface that reflects light evenly
- Simultaneous concerns addressed including pores, fine lines, and pigmentation in one treatment
- Long-lasting results as the collagen rebuilt during healing continues to improve skin for up to twelve months after treatment
- Fewer sessions needed compared to non-ablative alternatives. One to two sessions often achieve what takes five or more with lighter treatments.
- Fractional technology reduces risk and downtime compared to older fully-ablative CO2 methods
Fractional CO2 vs Fully Ablative CO2: What Is the Difference?
Understanding this distinction matters before booking.
| Fractional CO2 Laser | Fully Ablative CO2 Laser | |
| How it works | Treats a fraction of the skin surface in micro-columns | Removes the entire surface layer uniformly |
| Downtime | Five to ten days typically | Ten to fourteen days or longer |
| Recovery | Faster due to untreated bridges of healthy skin | More intensive wound care required |
| Risk on darker skin | Lower with proper settings | Higher PIH risk |
| Results | Significant improvement, builds over months | Very dramatic, higher risk profile |
| Sessions needed | One to three typically | Often one session but more intensive |
| Most common today | Yes, preferred approach | Reserved for very specific cases |
Fractional CO2 is the standard and preferred approach at most reputable aesthetic clinics in Karachi today including Beauish Studio. It delivers meaningful results with a more manageable recovery window and a safer risk profile for South Asian skin tones.
Step-by-Step: What Happens During a CO2 Laser Treatment Session?
Consultation and skin preparation Before the session, a detailed skin assessment takes place. Skin tone, scar type, scar depth, and any relevant medical history are reviewed. A pre-treatment protocol is often prescribed in the weeks before the session to prepare the skin and reduce PIH risk. This typically includes a topical retinoid and sometimes a mild lightening agent.
On the day of treatment The skin is thoroughly cleaned and a topical numbing cream is applied and left for 30 to 45 minutes. For more intensive sessions, local anaesthesia injections may be used to ensure full comfort during the procedure.
Laser application The fractional CO2 laser device is passed across the treatment area in controlled passes. Each pass delivers precise columns of laser energy to the skin. You will feel warmth and a mild prickling sensation. The device includes a cooling mechanism that helps manage the heat sensation during treatment.
Immediate post-treatment The skin will appear red and feel like a moderate to severe sunburn immediately after. A soothing ointment is applied before you leave. Full aftercare instructions, including a detailed day-by-day recovery guide, are provided.
Session duration: Typically 30 to 60 minutes depending on the areas being treated and the intensity of the protocol.
CO2 Laser Treatment Downtime: What to Expect Day by Day
Downtime is the part most people want clarity on before committing, and it deserves a straight answer.
Day one to two: Skin is red, swollen, and feels tight and warm, similar to significant sunburn. Some pinpoint bleeding or weeping at treatment points is normal with more intensive protocols. A protective ointment is kept on the skin continuously.
Day three to five: The outer layer begins to peel and form small brown crusts. This is the normal and expected healing process. Do not pick or pull at any peeling skin. The skin beneath is still forming.
Day five to seven: Most of the visible peeling completes by this point. Skin underneath feels noticeably smoother. Redness is still present but the intense phase is largely over.
Day seven to fourteen: Redness gradually fades. Skin may still appear pink or slightly flushed. Makeup is generally permitted from around day seven depending on how the skin has healed.
Month one to three: Collagen remodelling continues beneath the surface. The skin continues to improve in texture, firmness, and scar appearance progressively across this window.
Month three to twelve: The most significant visible improvement in acne scar depth and skin quality is typically appreciated in this period as deep collagen continues to reorganise and build.
Recovery timeline varies based on the intensity of the session, individual healing response, and how carefully aftercare is followed.
How Many CO2 Laser Sessions Are Needed for Acne Scars?
Most people achieve meaningful improvement with one to two sessions of fractional CO2. This is one of the treatment’s key advantages over non-ablative alternatives that require five to eight sessions for comparable results.
The number of sessions depends on scar depth, skin type, and the intensity of the protocol used. Shallower, more surface-level scarring responds faster. Deep, long-standing atrophic scars may benefit from a second session scheduled six to twelve months after the first.
A consultation at Beauish Studio maps out a realistic session plan based on a proper assessment of the scar type and depth before anything is booked.
When Do CO2 Laser Results Appear?
Weeks one to two: Initial healing phase. Skin feels smoother once peeling settles, but scar improvement is not yet fully visible.
Month one to three: Texture noticeably smoother. Scar edges begin to soften as new collagen fills and supports the previously indented areas.
Month three to six: Visible reduction in scar depth and improved skin tone. The surface reflects light more evenly and makeup sits better.
Month six to twelve: The most significant phase of improvement as deep collagen remodelling progresses. Results continue building without additional sessions.
Improvement ranges vary. Surface-level and rolling scars tend to respond faster and more completely. Deep ice-pick and boxcar scars improve meaningfully but may retain some texture variation. Results are individual and consultation sets realistic expectations based on your specific scar pattern.
CO2 Laser Aftercare: What to Do and What to Avoid
Aftercare directly affects both how well the skin heals and the quality of the final result.
Do:
- Keep the skin moisturised with the prescribed ointment continuously in the first few days
- Wash the face gently with a mild cleanser as directed, starting from day two or three
- Apply SPF 50 every morning once the skin has healed sufficiently. Sun protection during and after the healing phase is critical
- Attend follow-up appointments as scheduled so healing can be assessed
- Use any prescribed topical products for post-treatment skin support
Don’t:
- Pick, scratch, or forcibly remove any peeling or crusting skin. This is the single most common cause of scarring or pigmentation issues post-laser
- Expose healing skin to direct sunlight without SPF. UV exposure during healing significantly increases PIH risk
- Apply makeup until the provider confirms the skin is ready, usually from around day seven
- Enter saunas, steam rooms, or do intense exercise for the first week
- Use retinol, acids, or any active skincare products until the skin is fully healed and the provider has cleared them
Possible Side Effects of CO2 Laser Treatment
Side effects are expected during the healing phase and are a normal part of the process.
- Redness, swelling, and warmth in the first few days. Normal and expected.
- Peeling and crusting from day two through seven. Do not interfere with this process.
- Prolonged pinkness or redness after the initial healing, which fades gradually over two to four weeks.
- Temporary dryness and sensitivity once the peeling phase completes.
Risks to be aware of:
- Post-inflammatory hyperpigmentation is the most clinically significant risk on medium to dark skin tones. It is reduced substantially with proper pre-treatment preparation, correct laser settings, and strict SPF adherence post-treatment. Choosing a clinic with genuine experience treating South Asian skin tones is essential.
- Infection risk exists if the healing skin is not kept clean and properly protected. Sterile technique and correct wound care minimise this.
- Scarring from CO2 laser is rare when performed correctly but is a risk if settings are too aggressive for the individual’s skin or if aftercare is not followed.
CO2 Laser Treatment Cost in Karachi
Session intensity and protocol. A full-face fractional CO2 session at moderate intensity is priced differently from a more intensive deep resurfacing session targeting severe scarring. The protocol is customised per patient.
Treatment area size. Full face treatment costs more than targeting only the cheeks or a specific scarred zone.
Number of sessions. One session achieves meaningful improvement for many people. A two-session plan for more significant scarring carries a different total investment.
Pre-treatment preparation. Some patients require a preparation protocol in the weeks before the session that includes prescribed topicals. This is factored into the overall plan.
Clinic technology and provider expertise. Medical-grade fractional CO2 equipment and an experienced operator who understands South Asian skin tone calibration are reflected in the cost. These are not interchangeable with lower-grade equipment or less experienced providers when it comes to both safety and results.
Pricing at Beauish Studio is discussed after a skin and scar assessment at consultation. Book your session for a transparent and personalised cost breakdown.
CO2 Laser vs Microneedling vs Chemical Peel for Acne Scars
Three of the most searched acne scar treatments in Karachi. Here is how they compare directly.
| CO2 Laser Treatment | Microneedling | Chemical Peel | |
| Depth reached | Deep dermis | Mid dermis | Upper to mid dermis |
| Best scar type | Moderate to severe rolling, boxcar scars | Mild to moderate scarring and texture | Shallow scarring, post-acne marks |
| Sessions needed | One to two | Three to five | Four to six |
| Downtime | Five to ten days | One to two days | Three to seven days depending on peel depth |
| Results timeline | Three to twelve months building | Two to six months building | Visible from session two or three |
| PIH risk on dark skin | Higher, requires careful calibration | Low to moderate | Moderate, depends on peel depth |
| Best combined with | Microneedling for maintenance after | CO2 for deeper scars, peels for marks | PRP or skin boosters for recovery |
For moderate to severe acne scarring in Karachi, CO2 laser delivers the most significant structural improvement. Microneedling and chemical peels serve different depths and are appropriate for either lighter concerns or ongoing maintenance after CO2.
Many clients at Beauish Studio follow an initial CO2 laser session with periodic microneedling or chemical peel maintenance to sustain and build on the results.

Frequently Asked Questions (FAQs)
Is CO2 laser treatment painful? A numbing cream is applied 30 to 45 minutes before the session. Most people experience warmth and a mild prickling sensation during treatment rather than significant pain. Discomfort is managed throughout the session.
How long is the downtime after CO2 laser treatment? Fractional CO2 typically involves five to ten days of visible recovery. The first few days are the most intensive. Most people return to normal activity and light makeup around day seven, with redness continuing to fade over the following two to three weeks.
How many CO2 laser sessions do I need for acne scars? One to two sessions achieves meaningful improvement for most people. Session count depends on scar depth and severity. Your provider confirms the plan after a proper scar assessment at consultation.
Is CO2 laser safe for darker skin tones? Fractional CO2 can be performed on medium to darker skin tones with proper calibration, pre-treatment preparation, and strict post-treatment SPF adherence. The risk of PIH is real and manageable with the right protocol. At Beauish Studio, skin tone is assessed in detail before CO2 laser is recommended.
When will I see final results from CO2 laser treatment? Initial texture improvement is visible once healing completes, around weeks two to three. Significant scar reduction and skin quality improvement builds progressively from month three through twelve as deep collagen remodelling continues.
