The fractional CO2 laser (10,600nm) is the most powerful skin-resurfacing technology available. It vaporizes microscopic columns of tissue while leaving healthy skin between them to drive rapid healing. The result is dramatic improvement in deep wrinkles, scars and severe sun damage—at the cost of real downtime and careful patient selection.
The Science
The CO2 laser emits a 10,600nm beam that is intensely absorbed by water—the main component of skin. That energy instantly vaporizes (ablates) tissue. Older fully-ablative resurfacing treated the entire surface, giving spectacular results but weeks of raw healing.
Fractional delivery changed the equation: the beam is split into a grid of microscopic columns (microthermal zones) that ablate only a fraction of the skin, leaving healthy tissue between them as a reservoir for rapid re-epithelialization. Each column triggers intense collagen remodeling in the dermis. Over weeks the skin rebuilds smoother, tighter and more even—softening deep wrinkles, resurfacing scars and erasing sun damage—while downtime drops to days rather than weeks.
Fractional CO2 is the heavyweight of resurfacing: nothing matches its power on deep wrinkles and scars—but its ablative nature demands strict screening, especially on darker skin.
The Process
Assess skin type and indication; CO2 is best on Fitzpatrick I–III.
Topical (and sometimes nerve-block) anesthesia for comfort.
The fractional grid is delivered at chosen density and depth.
Skin oozes then crusts and peels over 5–10 days as it heals.
Indications
Smooths perioral and periocular lines other devices cannot.
Resurfaces and remodels pitted and raised scars.
Erases dyschromia, roughness and pre-cancerous change.
Tightens and smooths the eye area.
Why CO2
Unmatched on deep wrinkles, scars and severe damage.
Significant collagen contraction and remodeling.
Results endure for years with sun protection.
Density and depth tuned from light to aggressive.
Clinical Evidence
Dermatologic Surgery · 2009
Marked improvement in wrinkles and texture with a single or few treatments.
Lasers in Surgery and Medicine · 2010
Significant scar depth reduction across treatment courses.
Skin Safety
| I | II | III | IV | V | VI | |
|---|---|---|---|---|---|---|
| Light Density | Safe | Safe | Safe | Caution | Caution | Not recommended |
| Aggressive Density | Safe | Safe | Caution | Caution | Not recommended | Not recommended |
CO2 carries the highest post-inflammatory hyperpigmentation risk of any device covered here. It is best on Fitzpatrick I–III; types IV–V require very conservative settings and pre/post pigment management; type VI is generally not recommended—use RF microneedling instead.
Safety
Class IV laser with a smoke plume—use eyewear and a surgical smoke evacuator. Strict aseptic aftercare prevents infection of the ablated surface. Pre-treat darker skin to reduce PIH risk and never treat over active infection. This is a physician-level procedure in most jurisdictions.

For Operators
| Area | Energy | Pulse | Spot | Freq | Cooling | Passes |
|---|---|---|---|---|---|---|
| Full Face (light) | Low energy | µs | Fractional grid | — | None | 1–2 |
| Scars (deep) | High energy | µs | Fractional grid | — | None | 1 |
| Periocular | Low–mid | µs | Fractional grid | — | None | 1 |
When to choose ablative power over gentler options.
Sub-surface RF via needles.
✓ Pros
Far safer on dark skin; less downtime.
✕ Cons
Less dramatic on severe wrinkles than CO2.
Non-ablative photoacoustic.
✓ Pros
Minimal downtime.
✕ Cons
Gentler—less effective on deep wrinkles/scars.
CO2 is the choice for severe damage on light skin; for darker skin or shorter downtime, RF microneedling delivers strong remodeling more safely.
Operator Training
Advanced, physician-level training covering depth/density selection, PIH prevention on darker skin, infection control, smoke-plume safety and post-ablative wound care.
FAQ
Expect 5–10 days of redness, crusting and peeling depending on aggressiveness. Plan treatments around social/work schedules.
