Fractional Laser vs CO2 Laser: Which Skin Resurfacing Treatment Is Right for You?

If you’re researching advanced skin resurfacing treatments, you’ve probably come across both CO₂ laser and fractional laser — and you may be wondering which one delivers better results.

Both treatments are respected within aesthetic medicine. CO₂ laser is widely used in hospitals and specialist medical settings and is known for producing dramatic, transformative outcomes. Fractional laser systems, including the Lynton 2940 Resurface handpiece, offer a different but equally legitimate approach to skin renewal.

The key difference isn’t whether one works and the other doesn’t. It’s how they work – and how much recovery they require.

Let’s look at them objectively.

What Is CO2 Laser?

CO₂ laser resurfacing (10,600nm wavelength) is considered one of the most intensive forms of skin resurfacing available.

It works by targeting water within the skin and vaporising tissue. In traditional fully ablative treatments, the surface layer of the skin is removed while deeper layers are heated to stimulate collagen production.

Because of this depth and intensity, CO₂ laser can create significant improvements in:

• Deep wrinkles

• Advanced sun damage

• Severe acne scarring

• More mature, heavily damaged skin

CO₂ laser is commonly used in hospital environments and specialist medical settings due to the level of precision required and the post-treatment care involved.

Recovery typically includes redness, swelling and peeling for one to two weeks — sometimes longer depending on treatment depth. That downtime reflects the intensity of the resurfacing.

For the right candidate, CO₂ laser can deliver very impressive results — often after a single treatment.

What Is Fractional Laser (Lynton 2940 Resurface)?

Fractional laser technology works differently.

Rather than removing the entire surface of the skin, it creates thousands of microscopic treatment zones within the skin while leaving surrounding tissue intact. This “fractional” approach stimulates collagen production and skin remodelling in a controlled way, allowing faster healing.

The Lynton 2940 Resurface laser uses erbium (Er:YAG) technology (2940nm wavelength) to deliver precise micro-ablative columns into the skin.

Clinically, this means:

• Genuine resurfacing of treated areas

• Stimulation of new collagen production

• Improvement in texture, tone, fine lines and wrinkles

• Refinement of acne scarring and pigmentation

Because only a fraction of the skin is treated at one time, healing tends to be more predictable. Most clients experience redness similar to sunburn for several days, followed by light flaking or dryness.

While results may not appear as dramatic as deep CO₂ resurfacing after a single session, fractional 2940 laser produces meaningful improvement — often building progressively over a course of treatments as collagen develops over several months.

It is a true resurfacing treatment — simply delivered in a more controlled way.

What About “Fractional CO₂” Laser?

You may also see clinics advertising fractional CO₂ laser, which understandably adds confusion.

“Fractional” refers to how the energy is delivered — not the type of laser itself.

A fractional CO₂ laser still uses the CO₂ wavelength (10,600nm). It remains an ablative treatment, meaning it removes microscopic columns of tissue within the skin.

Compared to traditional fully ablative CO₂ resurfacing, fractional CO₂ can allow for somewhat faster healing because untreated skin remains between treatment columns. However, it is still considered a higher-intensity resurfacing procedure and typically involves more downtime than many non-CO₂ fractional systems.

In simple terms:

• Traditional CO₂: Fully ablative — entire surface treated

• Fractional CO₂: Ablative columns — higher-intensity resurfacing

• Fractional 2940 Er:YAG: Controlled micro-ablative resurfacing using a different wavelength

The terminology overlaps, but the intensity, depth, and recovery profile can differ significantly.

Fractional Laser vs CO2 Laser: Key Differences

Treatment Approach

Traditional CO₂: Fully ablative — removes surface layers
Fractional CO₂: Ablative columns — deeper intensity
2940 Fractional Er:YAG: Controlled micro-ablative columns

Intensity

CO₂ (traditional and fractional): High-intensity resurfacing
2940 Fractional: Precision-controlled resurfacing

Downtime

CO₂: 1–2 weeks or longer depending on depth
2940 Fractional: Several days of redness and light peeling

Results Pattern

CO₂: Often significant change after one treatment
2940 Fractional: Gradual improvement over multiple sessions

Price (UK Examples)

CO₂: Typically £800–£1,500+ per session
2940 Fractional: Typically £250–£700 per session

Is One Better Than the Other?

Not inherently.

CO2 laser remains a gold-standard treatment for deep resurfacing and can be the most appropriate option for advanced skin ageing or severe scarring – particularly where a patient is prepared for longer recovery.

Fractional 2940 laser is often chosen by clients who want genuine resurfacing and collagen stimulation but prefer a more staged approach with shorter downtime.

The difference is not about superiority.

It is about intensity, recovery, and suitability.

Why We Introduced the Lynton 2940 Fractional Laser

At Radiant Living Medispa near Wigan, our focus is selecting treatments that offer clinically meaningful results while aligning with the needs and lifestyles of our client base.

The Lynton 2940 fractional handpiece allows us to:

• Deliver real resurfacing results

• Improve texture and acne scarring

• Stimulate collagen effectively

• Offer controlled healing with predictable recovery

For many clients, that balance between results and downtime is important.

Where more severe scarring or advanced ageing is present, a more intensive resurfacing approach — such as CO₂ laser — may be appropriate. The key is assessing this properly at consultation.

The Bottom Line

If you’re deciding between fractional laser and CO₂ laser, the real question isn’t:

“Which is stronger?”

It’s:

“Which is appropriate for my skin, my concerns, and my lifestyle?”

Both treatments have an established place in aesthetic medicine.

The right choice depends on:

• The severity of your skin concerns

• Your tolerance for downtime

• Your expectations

• Your overall skin health

A thorough consultation is the only way to determine that properly.

If you’d like personalised advice on whether fractional laser resurfacing is suitable for you, book a laser consultation at Radiant Living Medispa near Wigan and we’ll guide you honestly through your options.

Frequently Asked Questions

1. Is fractional laser safer than CO₂ laser?

Both treatments are safe when performed by trained, experienced practitioners. The main difference lies in intensity and downtime. CO₂ laser (including fractional CO₂) is typically more aggressive and requires longer recovery. Fractional 2940 laser offers a more controlled resurfacing approach with shorter downtime, which may suit clients who prefer a staged treatment plan.

Safety always depends on correct patient selection, medical history, and appropriate aftercare.

2. How many treatments will I need?

CO₂ laser resurfacing is often performed as a single, deeper treatment.

Fractional 2940 laser treatments are usually carried out as a course of 2–4 sessions, spaced several weeks apart, allowing collagen to build gradually and results to develop progressively.

The right approach depends on the severity of the concern and how much downtime you are prepared for.

3. Which laser is better for acne scarring?

Both CO₂ laser and fractional 2940 laser can improve acne scarring.

CO₂ laser may be recommended for deeper, more severe scarring where intensive resurfacing is appropriate. Fractional 2940 laser is often suitable for mild to moderate acne scarring, particularly for clients who prefer less downtime and a more gradual improvement process.

A consultation is essential to assess scar type, skin type, and overall suitability.
