Crepey texture and fine lines: yes. Bags, hollows, and loose skin: no. Three different problems produce a tired under-eye and only one of them is a resurfacing problem.
CO2 laser under the eyes treats crepey texture, fine lines, and skin quality — it resurfaces the skin. It does not remove under-eye bags, fill hollows, or tighten loose skin, because those are structural and volumetric problems beneath the surface. Expect significant swelling for 48 hours and five to seven days of visible recovery. Two to three sessions, six to eight weeks apart.
Under-eye complaints get lumped together as "tired eyes," but three distinct things produce that appearance and they need entirely different treatments. Getting this wrong is the reason some patients finish a laser course disappointed.
Textural. That's what CO2 treats.
Fat pad prolapse. Structural — resurfacing won't move it.
Laxity. Excess skin isn't removed by laser.
Volume loss. That's filler or midface support.
Most patients have some of more than one. The question isn't which single problem you have — it's what proportion of what bothers you is textural, because that's the part CO2 will change.
If a fat pad is pushing forward against the lower lid, the bulge is what you're seeing. Improving the quality of the skin covering it doesn't reduce it — and by tightening and smoothing that skin, it can define the edge of the bulge more clearly than before.
Patients in this situation finish a course of laser with better skin and a more visible bag, which is not what they were told to expect. That's a candidacy question, and it should be settled before treatment rather than discovered after.
Periorbital skin is the thinnest on the body — substantially thinner than the cheek a few centimetres away. It also has fewer of the structures that skin relies on to heal after ablative treatment.
Settings appropriate for the face are not appropriate here. Energy and density are reduced, and the treatment is deliberately conservative. A practice running the same parameters across the whole face is treating the under-eye at settings calibrated for tissue several times thicker.
The area also swells more than anywhere else, which is the recovery feature patients most consistently underestimate.
Protective corneal shields are placed before treatment and remain in position throughout. This is not optional and it is not a topical shield — internal shields sit directly on the eye under anesthetic drops. Any practice treating this close to the eye without them is doing something wrong.
Allow a full week minimum, and don't book within two weeks of anything that matters. More detail across all devices: laser downtime compared.
Ablative CO2 carries meaningfully higher post-inflammatory hyperpigmentation risk above Fitzpatrick IV, and that applies here as elsewhere.
For deeper skin tones wanting under-eye textural improvement, RF microneedling delivers energy below the epidermis rather than through it, and Erbium produces less residual heat than CO2. Both are frequently better choices. See our guide to treatment selection by skin tone.
With filler. Where hollowing and texture coexist, both need addressing — but generally in separate appointments. Sequencing matters: treating one first often changes how much of the other is actually needed, and patients who fill first sometimes find they need less resurfacing than expected.
With neurotoxin. Crow's feet that appear only on smiling are dynamic and respond to neurotoxin. Lines visible at rest are static and need resurfacing. Most patients with crow's feet have both, and treating only one leaves half the problem.
With Pico. Where pigmentation accompanies texture, Pico and CO2 can be combined in a single session rather than run as two separate courses.
Under-eye is the area where I turn the most people down — not because the treatment is risky, but because a meaningful number of patients asking for it have bags or laxity rather than texture. Resurfacing does nothing for those, and saying so takes five minutes and saves someone a course of treatment plus a week of swelling for no result.
Can CO2 laser be used under the eyes?
Yes. Fractional CO2 is used on the periorbital and infraorbital skin at conservative settings, with protective corneal shields in place. The skin here is the thinnest on the body, so parameters appropriate for the cheek are not appropriate for the under-eye, and treatment requires settings adjusted specifically for the area.
Does CO2 laser get rid of under-eye bags?
No. Under-eye bags are usually prolapsed orbital fat pushing forward against the lower lid, which is a structural problem beneath the skin. CO2 resurfaces the skin surface and does not reposition or remove fat. Improving the skin over a bag can make the bag more apparent rather than less. True fat pad prolapse requires surgical assessment.
Does CO2 laser tighten loose under-eye skin?
It improves skin quality and produces some collagen remodeling, but it does not remove excess skin. Skin you can pinch and lift away from the lower lid is laxity that resurfacing will not correct. Mild laxity may respond to RF microneedling, while significant excess skin is a surgical matter.
What does CO2 laser actually fix under the eyes?
Crepey texture, fine lines including crow's feet, general skin quality, and sun damage in the periorbital area. It works on the surface and the upper dermis. If the concern is texture you can see when the skin is at rest, CO2 addresses it. If the concern is a bulge, a hollow, or loose skin, it does not.
How much downtime is there after CO2 laser under the eyes?
Swelling is the dominant feature and is more pronounced here than elsewhere on the face — periorbital tissue swells readily, and the first 48 hours can involve significant puffiness. Redness and fine flaking resolve over five to seven days, with residual pinkness fading over the following weeks. Allow at least a week before any event.
Is CO2 laser safe around the eyes?
It is performed safely as a routine treatment with appropriate precautions. Protective corneal shields are placed before treatment and remain in position throughout. Settings are reduced relative to facial parameters because the skin is markedly thinner. The main risks are prolonged redness, pigment change in deeper skin tones, and rarely scarring or ectropion with excessive treatment.
Is CO2 laser under the eyes safe for darker skin tones?
Ablative CO2 carries a meaningfully higher risk of post-inflammatory hyperpigmentation above Fitzpatrick IV, and that risk applies in the periorbital area as elsewhere. For deeper skin tones, RF microneedling or Erbium are frequently more appropriate choices for under-eye texture. This is assessed individually rather than by a general rule.
How many sessions are needed for under-eye CO2?
Typically two to three sessions spaced six to eight weeks apart, depending on the extent of textural change. Collagen remodeling continues for three to six months after each session, so the result seen at three months is not the final result.
Can CO2 laser be combined with under-eye filler?
They address different components and are frequently used together, but generally in separate appointments rather than the same session. Where volume loss and textural change coexist, sequencing is decided at consultation — treating one first often changes how much of the other is actually needed.
If the skin lifts away, or there's a bulge you can see in profile, resurfacing isn't the answer — and Dr. Mortazavi will tell you that at consultation rather than after a course of treatment.
