In short. Redness after carbon dioxide resurfacing is the pink flush of healing skin rebuilt with a new blood supply. It normally fades over weeks into months, in step with the depth treated; redness that worsens, breaks the surface, or comes with pain, warmth or discharge needs review rather than waiting.
Key points
- Redness is a direct consequence of the depth treated, not a sign of failure.
- Expected: gradual fading, dryness and itch, tightness easing, sun and heat sensitivity.
- Make-up can cover most colour once the surface has closed.
- Sun, heat, saunas and flushing exercise slow the settling.
- Worsening redness, broken or blistered skin, discharge, or fever with spreading redness need review.
Why does the skin stay pink?
Healing skin is rebuilt with a new blood supply, and new vessels close to the surface are what give it a pink or flushed appearance. The more heat was delivered into the tissue, the more inflammation there was, and the longer that rebuilding takes. Redness is therefore a direct consequence of the depth treated, not a sign that something has gone wrong, and it fades from weeks into months rather than overnight. Prolonged redness is not on its own a sign that the treatment was too strong; it is the expected consequence of the heat the deeper option delivers, and that heat is what allows it to reach deeper changes.
What is normal inside the pink phase?
Redness that is gradually fading. A surface that is dry, and sometimes itchy, as it renews. Tightness that eases. Sensitivity to sun and to heat. Make-up that covers most of the colour once the surface has closed. And a face that looks better in the morning than in the evening, because activity and warmth increase the flush. All of these are expected, and they do not mean the treatment has failed or that the plan was wrong.
What slows the redness down?
Sun exposure, heat, saunas, exercise that makes you flush, and picking or scrubbing the surface while it renews. Strict sun protection during and after healing is not a general recommendation; it is the single measure most likely to affect both how fast the redness settles and how the skin ends up pigmented. A patient who cannot keep out of the sun for the weeks after treatment should not have the treatment.
Expected healing and findings that need review
| Expected healing | Needs review | |
|---|---|---|
| Colour | Pink, fading gradually | Worsening rather than fading |
| Surface | Dry, sometimes itchy, renewing | Broken, blistering or discharging |
| Sensation | Tightness that eases; sun and heat sensitivity | Increasing pain or warmth; fever with spreading redness |
| Timing | Weeks into months | Persistent well beyond the expected weeks |
| Texture | Settling towards even | Remaining uneven or marked where it should have settled |
| Pigmentation | — | Appearing and then deepening rather than fading |
| Cold sores | — | A first outbreak during healing |
Most of the pink phase is healing, but the items in the right-hand column are reasons to be seen rather than to wait. Redness that is worsening rather than fading, a surface that has become broken, blistered or discharging, and increasing pain or warmth with fever and spreading redness all belong in that column.
When should redness be reviewed?
Persistent redness well beyond the expected weeks, and a surface that remains uneven or marked where it should have settled, are the findings that need an assessment rather than reassurance. Two further signals matter: a cold sore appearing for the first time during healing, and any change in pigmentation that appears and then deepens rather than fading. Increasing pain, increasing warmth, or fever with a spreading redness also warrants review.
Covering the redness while it settles
Once the surface has closed, cover make-up is usually possible and most people use it. During the raw phase it is not, because there is an open wound. The practical arrangement is to plan for a period when the face is visibly healing and a longer period afterwards when it can be covered but is still pink underneath.
Planning the weeks before treatment
The most useful preparation is to know, before the treatment, roughly how many weeks of pink the plan implies and to arrange your calendar and your expectations around that number. A patient told it will be a few days who then spends a month flushed will worry. A patient told it will be weeks who then spends a month flushed has simply had the treatment.

Frequently asked questions
How long is the pink phase after the deeper option?
Weeks, and the honest answer is that it varies with the depth treated and with how the individual skin heals. Redness commonly persists for several weeks and fades gradually over months. A plan that describes the recovery in days, when it uses a depth that heals in weeks, has given you a number that will not match your experience.
Can I cover the redness with make-up?
Once the surface has closed, cover make-up is usually possible and most people use it. During the raw phase it is not, because there is an open wound. The practical arrangement is to plan for a period when the face is visibly healing and a longer period afterwards when it can be covered but is still pink underneath.
Is redness a sign that the treatment was too strong?
Not on its own. Prolonged redness is the expected consequence of the heat that the deeper option delivers, and that heat is what allows it to reach deeper changes. What would suggest a problem is redness that worsens rather than fades, or that comes with pain, blistering or discharge.
Risks & Limitations
- Both options are ablative: each removes a layer of skin deliberately and leaves a wound that must heal.
- Treated skin can heal darker or lighter than it was. The risk is higher in darker skin, with more heat, and with sun exposure during healing.
- Redness after the deeper option lasts weeks, and the raw phase can last a week or more.
- Infection and delayed healing are uncommon and are why the depth and the aftercare matter; a cold sore flare during healing can leave a scar.
- Choosing too shallow a depth spends the healing without changing the wrinkle, which is a real risk of the shallower option.
When to Seek Care
- Redness that is worsening rather than fading, or skin that has become broken, blistered or discharging.
- Increasing pain, increasing warmth, or fever with a spreading redness.
- A cold sore outbreak during healing, or pigmentation that is deepening rather than settling.
- Difficulty breathing or chest pain — seek emergency care immediately.
