Understanding Acne Scars
Acne scars can linger long after breakouts have faded. These marks are often not just discolouration, but changes in skin texture and structure. Deep “ice pick,” “boxcar,” or “rolling” scars form when inflammation from acne disrupts the skin’s natural healing process, leading to collagen loss and uneven texture.
Topical creams can help with pigmentation, but they can’t rebuild the lost structure beneath the skin. That’s where CO₂ laser resurfacing offers something different—it helps remodel the skin from within.
How CO₂ Laser Resurfacing Works
CO₂ laser resurfacing uses a precise beam of light energy to gently remove damaged skin layers while stimulating new collagen growth underneath. The science behind it is simple yet powerful:
Targeting water in the skin:
The CO₂ laser emits light that’s absorbed by water molecules in the skin. Since skin is largely made of water, this energy is converted into heat, which carefully vaporizes microscopic layers of damaged tissue.Creating micro-channels of renewal:
Modern fractional CO₂ systems don’t treat the entire surface at once. Instead, they create tiny, evenly spaced micro-injuries surrounded by healthy tissue. This design allows faster healing while still triggering significant collagen production.Stimulating deep collagen repair:
As the skin repairs these micro-channels, new collagen fibers form and tighten. Over time, this rebuilding process can smooth indented scars and refine overall texture.Revealing renewed skin:
As healing progresses, the outer layer of skin naturally exfoliates, revealing fresher, smoother, more evenly toned skin beneath.
Benefits for Acne Scarring
CO₂ laser resurfacing offers a multi-layered approach that makes it especially effective for acne scars:
Texture Refinement: Helps fill and smooth depressed scars.
Skin Tone Correction: Can improve post-inflammatory pigment irregularities.
Collagen Renewal: Supports long-term skin health and resilience.
Clients often describe their skin as feeling firmer and more even, with makeup sitting better and light reflecting more evenly off the surface.
What to Expect Before, During, and After
1. Consultation and Preparation
Your journey starts with a personalized consultation. At Infinite Medical Spa, we assess your scar type, skin tone, and medical history to ensure CO₂ resurfacing is the right approach. You may be advised to pause certain products (like retinoids) and focus on gentle hydration before treatment.
2. During Treatment
The procedure typically takes about an hour for a full face. A topical numbing cream—and sometimes a local anesthetic—helps keep you comfortable. You’ll feel warmth or mild tingling as the laser passes across the skin.
3. Immediately After
Expect redness and a sensation similar to a sunburn. Swelling may appear for a day or two, followed by light peeling or flaking as your skin renews itself. Keeping the skin hydrated and protected is essential during this stage.
4. Recovery and Results
Most people take about a week before resuming makeup or public activities. Full collagen remodeling unfolds over several months, and results continue to improve with time. The smoother texture and clearer tone can last for years with proper skincare and sun protection.
Who Makes a Good Candidate
CO₂ laser resurfacing may be right for you if:
Your acne has been inactive for several months.
You have visible textural scarring that hasn’t improved with milder treatments.
You can commit to downtime and follow aftercare closely.
For darker skin tones, additional care and customized laser settings help reduce risks of pigmentation changes. That’s why professional evaluation is so important.
Safety, Realism, and Results
CO₂ resurfacing is one of the most effective modalities for improving acne scars, but it’s not instant or magic. The goal is meaningful, visible improvement—not necessarily perfection.
When performed by qualified professionals using medical-grade equipment, this treatment is considered safe. Temporary side effects like redness or sensitivity are normal and typically resolve within a week or two. Your provider will guide you on aftercare, including gentle cleansing, hydration, and diligent sun protection.

Frequently Asked Questions
How many CO₂ laser treatments will I need?
This depends on your skin and the type of scars. Some see noticeable improvement after one treatment, while others benefit from two or more sessions spaced several weeks apart.
When will I see results?
Early results appear within a few weeks, with optimal improvement over three to six months as collagen continues to rebuild.
Is it painful?
With numbing and local anesthetic, most people tolerate it well. Expect a warm or prickly sensation during treatment and mild tenderness afterward.
Can I wear makeup afterward?
Usually after about a week—once peeling has finished and the skin barrier has healed.
Can darker skin tones be treated?
Yes, though extra care is needed. With proper assessment and adjusted laser settings, many clients with medium to darker complexions can achieve beautiful results safely.
