CO₂ vs Fraxel vs Erbium: Untangling the Laser Names

Fraxel did to fractional lasers what Google did to search engines: the brand became the verb. Fraxel (by Solta Medical) was the pioneering fractional laser brand, and its name stuck so hard that many people — and plenty of clinic menus — now use 'Fraxel' to mean any fractional laser treatment. So when someone searches 'CO₂ Fraxel laser treatment', they are usually mixing a laser type (CO₂) with a brand (Fraxel) to describe one real thing: fractional CO₂ resurfacing.

The distinction matters because the actual Fraxel devices and CO₂ lasers behave very differently. The most widely used Fraxel modes — 1,550nm erbium-glass and 1,927nm thulium — are non-ablative: they heat columns of tissue without vaporising the surface, giving lighter results per session with minimal downtime. Fractional CO₂ at 10,600nm is ablative: it removes tissue, resurfaces powerfully, and asks for roughly a week of visible recovery in return.

Put the marketing aside and there are three technologies to compare. CO₂ (10,600nm) vaporises tissue with significant residual heat — the heat drives strong collagen remodelling and also creates the downtime. Erbium YAG (2,940nm) is absorbed by water even more strongly, so it removes tissue very precisely and superficially with much less heat spread — a lighter ablative with faster recovery and gentler per-pass collagen stimulus. Fraxel-type non-ablative lasers heat dermal columns without removing any surface at all.

As a rule of thumb: the deeper and more structural the problem, the more the ablative end of the spectrum earns its downtime. Established acne scars and deeply etched lines favour fractional CO₂. Finer lines, lighter texture work and thin-skinned areas can suit erbium's precise, low-heat ablation. Mild texture, tone and 'my skin looks tired' concerns — or patients who cannot show any downtime — fit the non-ablative series approach.

Skin tone bends the rule: in Asian and darker skin tones, every step up the ablative spectrum raises post-inflammatory hyperpigmentation risk, so a doctor may deliberately choose a gentler technology, or a conservative CO₂ protocol, over the theoretically stronger option. The best laser on paper is not the best laser for every face — which is why this decision belongs in a consultation, not a search bar.

One tail note for a question we see often: 'Fraxel laser for stretch marks' is a real search, and fractional resurfacing genuinely is used on stretch marks — at DrPlus this sits within the dedicated stretch-mark programme, where fractional CO₂ is one tool among several and honest expectations (improvement, not disappearance) are set at assessment.

Clinic menus are full of names — Fraxel, eCO2, AcuPulse, UltraPulse, 'Fraxis', 'fractional laser rejuvenation' — and no patient should need to memorise device catalogues. You only need three questions, and any credible clinic will answer them without hesitation.

First: is the treatment ablative or non-ablative — does it remove tissue or not? That single answer predicts the downtime and the per-session power. Second: what wavelength or laser type is the device — CO₂, erbium, thulium, something else? That tells you where it sits on the spectrum above. Third: who assesses my skin and sets the parameters — a doctor, or whoever is free that day? Because in resurfacing, the settings chosen for your skin matter more than the badge on the machine.

DrPlus offers fractional CO₂ resurfacing — the ablative end of the spectrum — at our doctor-led clinic in Iskandar Puteri, about 30 minutes from the Singapore checkpoint. It is used for acne scars, texture, pores and fine lines, with adjusted settings for delicate areas and conservative parameters for PIH-prone skin tones. For pigment-led concerns we use pico laser, and for surface-sparing collagen work, RF microneedling — so the technology is matched to the problem rather than the other way round.

If you arrived here searching for 'CO₂ Fraxel', the practical translation is: the treatment you are researching is fractional CO₂, and the useful next step is a consultation where a doctor examines your skin and tells you whether the ablative end of the spectrum is what your concern actually needs. Consultations are private, and there is never an obligation to proceed.
