CO2 resurfacing buys real change with a real week of healing — decide with that week in front of you.
CO2 resurfacing is not a lunchtime treatment and it is not a facelift. It improves the surface of the skin, and it asks for five to seven raw days and weeks of pinkness in return. This site is about that trade: whether you are a candidate, what the week costs you, what the pigment risk really means in your skin, and when the honest answer is to do something else.
Medically reviewed by Ke He, MD, head of skin and laser aesthetics at Chongqing West District Hospital. Healing and pigment response vary between individuals, and no result is guaranteed.
What you are actually agreeing to
Resurfacing removes the surface of the skin in a controlled way so that new skin grows back in its place. That is a real change and a real injury. First, it is a surface treatment: texture, fine lines, sun damage and the surface of some scars improve, while sagging, lost volume and deep pigment do not. Second, the surface usually closes in five to seven days, and that week is raw, weeping and socially impossible; pinkness can persist for weeks afterwards. Third, skin that produces pigment easily can over-produce it as it heals, which is more common and more stubborn in darker skin and can take months to settle. Fourth, burns, blistering and scarring occur, and pigment that is lost may not return. Fifth, the improvement is long-lasting but not permanent, and it is not a facelift. If the week and the risk are acceptable to you, this can be a good treatment. If they are not, a lighter plan is a better answer.
What resurfacing changes, and what it leaves exactly as it was
The useful boundary is not between good and bad results. It is between problems the surface of the skin causes and problems it cannot reach at all.
Surface texture, replaced
The damaged surface is removed and new skin grows in its place, with collagen rebuilt underneath. Roughness, crêpey fine lines and unevenness that makes light sit badly improve, usually noticeably. This is the one thing the treatment does, and in the right skin it does it well.
Sun damage and surface pigment
Removing the surface removes the pigment sitting in it, so freckling and sun spots on the treated area usually lighten considerably. Pigment that lies deeper, and melasma-type pigment in particular, responds far less predictably and can darken instead of clearing.
The surface of some scars
Shallow rolling and boxcar acne scars soften, because their main problem is the edge between scar and normal skin. Deep, tethered scars change much less: the problem sits underneath, and resurfacing the surface does not release it. The aim is improvement, not removal.
Not laxity, and not a facelift
Resurfacing does not lift tissue that has descended, does not restore volume that has been lost, and does not change the shape of a face. A resurfacing course is not a facelift and is not a substitute for one, however good the skin looks afterwards.
Who this suits, and who should be offered something else
The good candidate can point at the problem: a specific area of texture, sun damage, fine creasing or the surface of scarring, rather than a general feeling of looking tired. They have skin that heals predictably, no active infection or inflammatory flare in the area, and no keloid tendency. They can take seven to ten days away from being seen, and they can keep the sun off the skin for months afterwards — which is part of the treatment rather than advice about it. They understand that the result is improvement and not erasure. A poor candidate is not an unhealthy person. It is someone whose real complaint is sagging, volume loss or deep pigment, someone whose skin darkens easily and who cannot commit to the protection that reduces that risk, someone whose healing is slowed by illness or medicine, and someone who needs the change to be invisible to other people. Each of those has an answer, and for several of them the answer is a lighter treatment or none.
How much skin is removed, and in what pattern
These are the two decisions that shape your week. Neither is a brand question, and both should be written into the plan in plain words before treatment day.
Ablative: the surface is removed
The stronger option, and the one that produces the more obvious change in texture, fine lines and the surface of scars. It is also the one that leaves skin open for five to seven days, with weeks of pinkness afterwards and a higher pigment risk. It is chosen when the problem genuinely needs the surface removed.
Non-ablative: the surface is left intact
Treatment works beneath an intact surface, so there is no open skin and recovery is measured in days of redness rather than a week. The change is subtler and usually arrives over a series of sessions. It is often the first plan tried in darker skin, and often the wiser one.
Fractional: columns with bridges between
A fractional pattern treats fine columns of skin and leaves untouched bridges between them, which speeds healing and lowers risk compared with treating an area continuously. The pattern decides far more about your week than the area does, and it is the question patients are least often told to ask.
How much of the face is treated
Whole-face treatment gives an even result and avoids a visible boundary; treating one region shortens recovery but can leave a hard edge where treated meets untreated skin. A common middle path treats the whole face lightly and the problem areas more deeply, in one plan rather than one setting.
The healing week, priced honestly
Treatment day itself is the easy part, because the face is treated under anaesthesia. You go home with skin that is raw, warm and weeping, and the surface usually closes within five to seven days. Swelling peaks around the second or third day, which surprises people who expected day one to be worst. Crusting, tightness and itching follow, and nothing should be picked at. That week has to be given up: it is not negotiable, and a plan promising a much shorter one is either removing less skin or treating less of the face. After the surface closes, the skin is red, sensitive and easily irritated, and make-up waits until then. Most people are presentable in public somewhere in the second week with cover, and the redness settles over weeks to months rather than days. Judging the result in the first fortnight is impossible and pointless, because what is visible then is a healing face and not the outcome.
What can go wrong, and how it should shape the decision
Redness, swelling, oozing, crusting and itching are expected rather than complications. Beyond those: infection, which is why antiviral cover is ordinarily prescribed and why increasing pain after the third day, spreading redness or a fever should be reported the same day; healing that lags in one area, which raises the risk of a scar; scarring itself, uncommon but real and more likely after infection, after treatment that was too deep for the skin, in people with a keloid tendency and on thin skin such as the neck; and pigment change in both directions. Darkening after treatment is common and usually settles with time and protection. Lightening is uncommon and can be permanent, and it is the complication with no good correction. Nothing here is a reason to refuse resurfacing for everyone. It is a reason to have the consent conversation properly, and to treat a plan that mentions no risk at all as information about the clinic rather than about the treatment.
The other answers, and which complaint each one treats
Resurfacing is the most demanding option, and it is not the right one for every problem. Non-ablative resurfacing, fractional radiofrequency microneedling and mechanical microneedling all work on texture and collagen with far less disruption, as a course of sessions rather than one appointment, and it is worth understanding what a lighter plan would achieve before agreeing to the harder one. Prescribed topical programmes and a series of chemical peels address pigment and mild surface change with no open skin at all. Where the problem is sagging tissue, lost volume or heavy eyelids, none of these is the answer and an operation is, which is a referral rather than a sales conversation. And where the change is mild, ordinary and noticed mainly by you, the honest alternative is to wait — ageing is gradual, nothing about the calendar imposes a deadline, and no treatment carries risk small enough to be worth taking for a change nobody else would see.
The physician responsible for these guides
This site is medically reviewed by Ke He, MD, Deputy Director of the Plastic Surgery & Aesthetics Medical Center and head of its skin and laser aesthetic service at Chongqing West District Hospital. Her practice is built on assessment before device: confirming what the pigment, the scarring or the texture actually is before choosing how to treat it, staging plans rather than treating everything at once, and judging progress against standardised photographs taken in the same light rather than against memory. Resurfacing decisions genuinely involve the rest of the team — the surgical view on whether an operation is the honest answer, and the dermatological view on pigment and on skin that has been irritated by treatment — and the hospital setting means a rare complication can be managed inside the same building rather than referred elsewhere. Read the full team profiles.
The comparisons that decide most resurfacing cases
Resurfacing is rarely chosen in isolation, and three comparisons do most of the work. Patients weighing pigment problems often need to choose between intense pulsed light and a picosecond laser, which are gentler routes with their own limits. Where the question is whether skin laxity can be improved without an operation, radiofrequency or ultrasound tightening sets out what energy devices can and cannot do about looseness. Where acne scarring is the reason for treatment, the acne scarring guides explain why scar type decides the technique rather than the other way round. And where the concern is sagging rather than surface, skin laxity starts from the problem rather than from the device.
The healing week, then the year
This timeline begins as a wound-healing schedule and continues as a treatment course: what closes and when, what appears later, when the result can honestly be judged, and how long it holds. Individual healing varies, and your own team's instructions take precedence over any general timeline.
The decision, in twelve parts
Each guide takes one decision a patient actually faces — candidacy, the healing week, pigment risk, how much skin to remove, scarring, complications, durability, preparation and refusal. Read the two or three that match where you are.

Frequently asked questions
Is CO2 resurfacing the same as a facelift?
No, and the confusion does real harm. A facelift repositions tissue that has descended; resurfacing replaces the surface of the skin and rebuilds collagen beneath it. Resurfacing will not lift a jawline, restore volume or change the shape of a face, and a resurfacing course is not a facelift in stages. If sagging is what bothers you, an assessment should say so rather than sell you a longer course.
How long will I be red after CO2 resurfacing?
The surface usually closes in five to seven days, and the redness that follows is measured in weeks rather than days. It fades gradually toward normal over the following months, and most people are presentable in public with cover somewhere in the second week. Fair and sensitive skin often stays pink longer, and on its own that is not a complication.
Is fractional treatment safer than treating the whole face continuously?
Fractional treatment leaves bridges of untouched skin between the treated columns, which speeds healing and lowers the risk compared with treating an area continuously. It is usually the safer pattern, and it is also the gentler result. Which pattern you are being offered should be stated plainly in the plan, because it changes your week more than the size of the treated area does.
Can CO2 resurfacing be done on skin that tans easily?
Often, with a different plan. Skin that produces pigment easily reacts more strongly to controlled injury, so treatment is usually lighter, primed for longer beforehand and staged over more sessions, with strict sun protection through the months afterwards. Some patients are advised against deeper treatment altogether. A clinic that treats every skin type identically is not assessing skin type at all.
How many CO2 resurfacing sessions will I need?
It depends on what is being treated and how deeply. Some plans are a single treatment; others are two to four lighter sessions spaced several months apart, which spreads the recovery and lowers the cumulative pigment risk. A plan that quotes a number of sessions before examining your skin is quoting a package rather than a treatment.
What happens at a resurfacing consultation at Chongqing West District Hospital?
The assessment comes first: what the problem actually is, whether it is a surface problem at all, how your skin heals and how it has behaved after previous treatment, and what your calendar can absorb. You should leave knowing what would be treated, in what pattern, what the healing week involves, what the pigment risk is in your skin, and what the alternatives are — including the option of doing nothing.
