CO₂ Laser Acne Scars: How Effective is CO₂ Laser?

By Alyssa Martinez @ItsMariaAlyssa

Acne scars can feel like a lingering reminder of past skin issues. If you’re like many people, the scars can affect your self-confidence long after acne has cleared up.

If you’ve been exploring options to treat acne scars, you must have come across CO₂ laser therapy as a potential treatment. The procedure targets damaged skin layers to stimulate collagen production to renew skin’s texture.

But how effective is CO₂ laser treatment at reducing acne scars? And, how does it compare to alternatives? Stay on this page for answers to those questions and more.

How Does CO₂ Laser Work?

CO₂ laser therapy is a form of skin resurfacing treatment that uses a high-energy laser to target and remove the top layer of skin cells. Unlike traditional laser treatments, CO₂ laser technology penetrates deeper layers of the skin which makes it more effective for treating deep acne scars. Here’s how the process works:

  • The CO₂ laser targets microscopic layers of skin cells to create tiny, controlled wounds in the skin. This way, it encourages your body’s natural healing process. This controlled damage stimulates collagen and elastin production, which helps reduce the appearance of scars over time.
  • CO₂ laser treatment uses a technique called “fractional technology,” which creates tiny treatment zones in the skin rather than affecting the entire surface. This allows for faster healing and less downtime. Untreated areas will remain intact to support the skin’s recovery.
  • The heat from the CO₂ laser not only resurfaces the skin but also boosts collagen levels deep in the dermis. Collagen is crucial for smooth, healthy skin, helping to “fill in” and improve the texture of acne scars.

How effective is CO₂ Laser for Acne Scars?

The effectiveness of CO₂ laser treatment for acne scars depends on factors like skin type, scar severity, and individual skin responses. Research has shown that CO₂ laser can significantly improve the appearance of acne scars, with many people experiencing smoother skin and reduced scarring. Here’s what you can expect in terms of results:

  • Visible Improvement in Texture: Most people see smoother, more even skin texture. Studies suggest that a single CO₂ laser treatment can lead to a noticeable improvement. However, full results typically visible over several months as collagen builds up in the skin.
  • Reduction in Scar Depth: CO₂ laser is particularly effective for reducing the depth of scars. Many people report a 50-70% improvement in the appearance of deep scars after 1-3 sessions, though results can vary.
  • Long-Term Results: Unlike topical treatments, CO₂ laser has lasting benefits. Since it promotes collagen production, the skin continues to improve over several months post-treatment. For many, these effects can last years, especially with a good skincare routine.

Potential Side Effects and Risks of CO₂ Laser

As with any intensive skin treatment, CO₂ laser therapy comes with potential risks and side effects. The most notable and most likely side effects is redness and swelling.

Most people experience redness and mild swelling after CO₂ laser treatment, which can last for several days to weeks. This is a normal part of the healing process as the skin recovers. So, it really shouldn’t even bother you.

CO₂ laser can sometimes cause temporary hyperpigmentation, especially in those with darker skin tones. Your provider might recommend pre-treatment skin care to reduce this risk.

It is also worth noting that the treated skin is often sensitive and prone to irritation post-procedure. You will want to avoid sun exposure and use only the recommended skin care products to protect the new skin.

Importantly, since CO₂ laser treatment involves creating small wounds, there is a slight risk of infection. It is important to follow post-care instructions which typically include avoiding unclean surfaces and applying prescribed ointments to prevent infection.

Most side effects are temporary and diminish as the skin heals. However, it is best to discuss these with your provider to ensure you’re a suitable candidate for CO₂ laser.

What is the Recovery Time for CO₂ Laser?

The recovery period for CO₂ laser treatment is generally 1-2 weeks. However, full recovery can take longer depending on your skin type and the intensity of the treatment.

On the first week, your skin will feel red, swollen, and possibly scabby. You’ll need to follow a strict skincare routine which involves gentle cleansing and application of healing ointments to speed up recovery.

On the second week, redness typically subsides, and skin starts to look smoother. You may notice some peeling as new skin emerges.

For some, redness may persist for several weeks. You can generally resume normal activities after two weeks, but sun exposure should be minimized as much as possible during the healing period.

The initial downtime can be challenging, but once healed, most people are pleased with the results. Religiously follow the aftercare instructions from your provider to speed up recovery and ensure optimal results.

How does CO₂ Laser Compare against Other Acne Scar Treatments

CO₂ laser isn’t the only option for acne scar treatment. Comparing it to other popular treatments can help you decide which option best suits your needs. Real quick, here is how it stacks up against other popular treatments;

  • Microneedling: This treatment uses tiny needles to create micro-injuries, and trigger collagen production similar to CO₂ laser but at a shallower depth. Microneedling is generally less invasive with minimal downtime but may not be as effective for deep scars.
  • Chemical Peels: Chemical peels can exfoliate and refresh the skin’s surface but don’t penetrate as deeply as CO₂ laser. They’re effective for minor acne scars and pigmentation but typically offer less improvement for deep scars.
  • Dermal Fillers: Fillers can temporarily “fill in” deep scars and make them less visible. While effective, this solution is temporary, lasting only a few months to a year, unlike CO₂ laser, which offers more permanent results.
  • Fractional Laser (Non-CO₂): Fractional lasers, like Fraxel, also use fractional technology but don’t go as deep as CO₂ laser. They can be beneficial for milder scars and require less downtime, though they may need multiple sessions for comparable results.

The Bottom Line

CO₂ laser offers an effective, long-lasting solution for those looking to reduce the appearance of acne scars. It’s one of the few treatments capable of targeting deep scarring by promoting collagen growth and resurfacing the skin. While the downtime and initial recovery can be challenging, the results can make it a worthwhile investment for many.

If you’re considering CO₂ laser treatment for acne scars, consult a board-certified skin or aesthetic doctor to assess your skin and discuss options. You will need a personalized plan to achieve the best results. So, reach out today to schedule your appointment;
