Does CO₂ Laser Permanently Remove Acne Scars? Fractional CO₂ Laser offers lasting, noticeable improvement, but results vary from person to person. It is considered the best option for deep scars, but no medical treatment can guarantee complete, permanent removal because skin naturally ages.
- Effectiveness: It noticeably improves the texture of Boxcar and Rolling scars.
- Longevity: Collagen remodeling from the treatment stays stable for years. Treated scars usually don’t come back, but aging can change your skin’s texture over time.
- Sessions Needed: Most people require 4 to 6 sessions for optimal results.
- Safety: The procedures are safe when performed by experienced dermatologists who follow proper preparation steps.
The Battle for Scar-free Skin in Chennai
Living in Chennai brings its own skin challenges. Strong sunlight, high humidity, and city pollution can damage your skin. If you’ve had severe acne, the struggle often continues even after the pimples are gone.
Deep, pitted acne scars can be very frustrating. Even after acne heals, scars may stay and affect your confidence and skin’s appearance. Many people who have tried creams, peels, microneedling, or other treatments still wonder: Can a CO2 laser permanently remove acne scars?
In this guide, our dermatology team focuses on the facts. We explain how Fractional CO2 Laser Resurfacing works for Indian skin and what results you can expect at Welona Chennai clinics.
Understanding Acne Scars and Why They Are Hard to Treat
To understand the treatment, it helps to know the cause. When an acne cyst becomes very inflamed, it can damage the skin beneath it. If the skin doesn’t make enough collagen while healing, a pit or depression forms.
Not all scars are alike, and CO₂ laser doesn’t work for every type:
- Ice Pick Scars: Deep, narrow punctures. (Often requires TCA Cross before laser).
- Boxcar Scars: Broad depressions with sharp edges. (CO₂ Laser is highly effective for these).
- Rolling Scars: Wide depressions with sloping edges. (These often need Subcision first to release the tether, followed by CO₂ Laser).
Expert Insight
Most patients in Chennai have a mix of different scar types. That’s why a single method alone usually isn’t enough; a personalized treatment plan is important.
How does the Fractional CO2 Laser Work?
CO2 laser resurfacing is a modern treatment that helps improve acne scars by boosting deep collagen remodeling. It can permanently improve the appearance of scars, but it doesn’t remove them completely. The fractional CO2 laser creates tiny injuries in the skin, which start the body’s healing process and collagen production, gradually smoothing scarred areas.
Old vs. New Technology
Traditional CO₂ lasers removed the entire top layer of skin. This worked but was risky, leading to prolonged recovery times and pigment issues, especially in Indian skin.
At Welona Clinic, we use Fractional CO₂ Technology, an ablative laser resurfacing treatment that uses focused light energy to create controlled micro-injuries in the skin. These micro-injuries trigger the body’s natural healing response, leading to the formation of new collagen.
Modern fractional CO₂ lasers do not treat the entire skin surface at once. Instead, they:
- Create microscopic treatment zones.
- Leave the surrounding skin intact for faster healing.
- Stimulate collagen remodelling over time.
This approach is more effective and safer than older, fully ablative lasers.
The Big Question: Are the Results Permanent?
This section is especially important. While CO₂ laser treatment is powerful, it cannot guarantee results.
Here is the truth from our dermatologists:
- The Results are Long-Lasting: After the laser helps your skin produce new collagen and fill the scar, the improvement usually lasts. The treated scar tissue doesn’t return. For most people, the smoother skin lasts a long time.
- The Aging Factor: Your skin keeps aging even after scars are treated. We lose about 1% of collagen each year. Over time, as your skin loses elasticity, some texture changes may recur due to aging, not because the treatment didn’t work.
- New Acne = New Scars: If you get new acne breakouts, you can develop new scars. That’s why, at Welona, we ensure your active acne is under control with medication before starting laser treatment.
Realistic Expectations of CO2 Laser Treatment
We focus on making significant improvements, not on achieving perfection. For deep scars, you can expect a 60% to 80% reduction in how visible they are. For most people, this change boosts confidence and means you won’t need heavy makeup.

Safety, Downtime, and Recovery
Fractional CO₂ laser is safe for Indian skin when used carefully and with the right approach. If the technique is wrong or too aggressive, there’s a higher risk of pigmentation, so expertise is very important.
CO₂ laser does involve downtime. Typical recovery includes:
- Redness and swelling for a few days
- Crusting or peeling for about a week
- Gradual skin normalisation over 2–3 weeks
While downtime is longer than that of non-ablative treatments, the depth of improvement is also greater, making it worthwhile for suitable candidates.
Get CO2 Laser At Welona Chennai: Step-by-Step
At Welona, lasers are handled by qualified doctors, not technicians. Our dermatologists understand the specific physics required for Indian skin to ensure safety. If you book a consultation at our branches, here is exactly what happens:
Step 1: Consultation & Mapping Our MD Dermatologist examines your scars. We map out which scars require Subcision, which require TCA Cross, and which require CO₂ Laser.
Step 2: Numbing (The Comfort Phase) We apply a medical-grade topical anesthetic cream for 45–60 minutes. This makes the procedure very tolerable. Most patients describe the sensation as “warm prickles.”
Step 3: The Laser Treatment. The doctor performs the procedure, which takes about 20–30 minutes for a full face. A specialized cooling device blows cold air on your face simultaneously to minimize heat sensation.
Step 4: Immediate Post-Care. Your face will feel hot, like a strong sunburn. We apply soothing antibiotic creams and ice packs immediately to bring the temperature down.

FAQ: CO2 Laser
Can a CO₂ laser remove chickenpox scars?
Yes, it is very effective for chickenpox scars, as they are similar to atrophic acne scars. It helps smooth the crater’s edges.
Will I need to take leave from work?
We recommend taking 3 to 4 days off. If you work from home, you can work, but your face will be red, and you will have ointment on it.
Can I wear makeup after the laser?
Not immediately. You must wait until the scabs have completely fallen off (usually Day 7). Applying makeup too early can cause an infection.
What happens if I go out in the sun?
This is critical. Exposing healing skin to the Chennai sun without protection can cause hyperpigmentation (darkening). You must use SPF 50+ and physical barriers (hat/scarf) for at least 4 weeks.
