In short. Ablative resurfacing removes the damaged surface layer of skin in a controlled pattern, and the skin that heals back is the result. It changes fine lines, pores, surface texture and irregular pigmentation, but it does not reach loose skin, lost volume or lines produced by movement.
Key points
- The treatment removes a layer of skin; what heals back is the result.
- It changes fine lines, pores, roughness and irregular pigmentation in that layer.
- It does not reposition sagged tissue or restore lost volume.
- Lines that appear only on movement are produced by muscle and remain.
- The raw healing phase is the treatment working, not a complication.
What does resurfacing remove?
The word resurfacing describes the treatment accurately, and it is worth taking literally. A layer of skin is removed, deliberately and in a controlled pattern, and the surface that appears afterwards is new skin produced by healing. Everything the treatment achieves comes from that, and everything it cannot achieve comes from it too. Understanding the removal explains both lists.
What the removal changes
Removing the damaged surface layer takes with it the fine creases, the roughness and much of the irregular pigmentation that sit in it. What heals back is smoother, and this is why ablative treatment changes fine lines, pores and surface texture more than anything non-ablative does. Old scarring also softens, partly because the surface around it is smoothed and partly because the healing response beneath it continues after the wound closes. These are real changes and they are among the more substantial available from a skin treatment.
What it does not reach
The layer removed is the surface. Nothing beneath it is repositioned, so skin that has sagged or dropped is unchanged. Nothing is added, so volume that has been lost is not restored. Muscle activity is untouched, so lines that appear only when you move your face are still there afterwards, because they are produced by the muscle and not by the skin. A plan that includes any of those three as something resurfacing will fix is describing a different treatment.
What happens between the laser and the result?
This is the part patients underestimate. Between the laser and the result there is a wound: raw skin, oozing, careful cleaning, and a period measured in days before the surface closes. How that wound heals decides how good the result is, which is why the aftercare instructions matter as much as the settings, and why sun exposure during healing is the commonest way a good treatment produces a disappointing outcome. Two patients treated identically can heal differently, and that variation is not a failure of the treatment.
Statements that misdescribe the treatment
- Resurfacing described as stimulating the skin, when what it does is remove a layer of it and let the skin rebuild.
- No mention of the raw phase, the oozing or the weeks of redness before you agree to anything.
- A promise that a particular wrinkle will be gone, when how the skin heals back is part of the outcome and cannot be predicted.
| What is being changed | Does resurfacing reach it? | What the treatment does | What it leaves |
|---|---|---|---|
| Fine lines, pores and surface texture | Yes | Removes the surface so smoother skin heals back | A raw phase and weeks of redness |
| Irregular pigmentation in the surface layer | Yes | Removes the layer holding it | Healing decides the final evenness |
| Old scarring | Partly | Softens it by smoothing around it and provoking healing beneath | A depressed scar remains depressed |
| Sagged or dropped skin | No | Nothing beneath the surface is repositioned | The looseness is unchanged |
| Lost volume | No | Nothing is added | The hollow remains |
| Lines that appear only on movement | No | Muscle activity is untouched | The line returns when you move |
| A deep static wrinkle | Partly | The surface is removed and heals smoother | It may improve without disappearing |
What that means for the decision
If what you want changed is the surface, this family of treatments is the one that changes it, and the question becomes how deep the removal needs to go. If what you want changed is position, volume or movement, the removal does not address it at any depth, and the honest answer is a different treatment rather than a deeper setting.

Frequently asked questions
Does resurfacing remove wrinkles or fill them in?
Neither, exactly. It removes the surface layer those fine wrinkles sit in, and the skin that heals back is smoother, so the wrinkle is much less visible. It does not fill anything, which is why a deep wrinkle that involves tissue beneath the surface may improve without disappearing, and why volume loss is not addressed at all.
Why does the skin have to be raw afterwards?
Because the treatment removes the surface, and a surface that has been removed has to be replaced by the skin healing. That raw phase is the treatment working rather than a complication of it. It is also why the healing period, and the sun protection during it, are as important to the result as the laser settings.
Will resurfacing help with acne scarring?
It usually softens scarring and makes it less noticeable, by smoothing the skin around the scar and provoking a healing response beneath it. It does not rebuild tissue that has been lost, so a depressed scar remains depressed even when it is far less obvious. Scars of certain types need a different approach entirely.
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.
