CO₂ Resurfacing Intensity Ladder
CO₂ resurfacing spans an intensity ladder from light fractional (low downtime) to deeper ablative (more downtime). Adjustable depth and density tailor intensity and recovery to the patient.
CO₂ resurfacing is a ladder, not a setting
One of the most useful things to understand about CO₂ resurfacing is that it isn’t a single intensity — it’s a ladder. The same platform can deliver a light refresh or a deep correction, and the art is matching the rung to the patient. The Alexa CO₂ Aesthetic offers adjustable depth and density for exactly this.
The rungs
- Light fractional — subtle skin-quality refresh; lower downtime, usually more sessions. Good for maintenance and early photoaging.
- Moderate fractional — stronger texture and tone correction; moderate downtime.
- Deep / ablative — maximum correction for significant texture, scars, or photoaging; the most downtime and the most careful patient selection.
How intensity is tuned
Two dials drive the ladder: depth (how far the energy reaches) and density (how much of the area is treated). Lighter, lower-density settings reduce downtime; deeper, denser settings correct more per pass. Adjustable pulse control lets a provider place a treatment precisely on the ladder.
Skin type and selection
Ablative CO₂ is generally best suited to lighter Fitzpatrick types due to melanin sensitivity; darker skin needs conservative settings, careful protocols, and post-care. Patient selection and provider judgment decide which rung is appropriate.

FAQs
What is the CO₂ resurfacing intensity ladder?
It's the range of CO₂ treatment intensities — from light fractional refresh with low downtime, through moderate fractional correction, to deep ablative resurfacing with maximum correction and the most downtime. Adjustable depth and density let a provider pick the right rung for the patient and goal.
How is downtime controlled?
By adjusting treatment depth and density. Lighter, lower-density fractional treatments mean less downtime but usually more sessions; deeper, denser treatments correct more in one pass but require longer recovery and more careful patient selection.
Which intensity is right for a patient?
It depends on goals, skin type, downtime tolerance, and provider assessment. Conservative settings suit maintenance and lighter skin-quality goals; deeper settings suit more significant texture, scar, or photoaging correction in appropriate candidates.
Does skin type affect intensity choice?
Yes. Ablative CO₂ is generally best suited to lighter Fitzpatrick types because of melanin sensitivity; darker skin requires more conservative settings, careful protocols, and post-care. Patient selection is essential.
