Can CO2 laser resurfacing treat stretch marks?

Yes, fractional CO₂ laser resurfacing can improve the appearance of stretch marks, but it does not reliably erase them. Research supports some improvement in texture and appearance, with limits: studies are small, results vary between individuals, and treatment can cause discomfort, redness and changes in skin colour.[1,2]

Can CO2 laser resurfacing treat stretch marks?

Fractional CO₂ treatment has clinical evidence behind it, but the useful question is how much improvement justifies the recovery for you. A randomised trial reported improvements in stretch marks after fractional CO₂ treatment; a wider review found that treatment evidence remained limited and varied between studies.[1,2]

Here is what that means before booking:

• Improvement is possible. Research reports changes in appearance, not dependable removal.[1,2]
• Recovery matters. Redness, discomfort and pigment changes belong in the decision, not just the consent form.[1,2]
• Individual assessment comes first. Your skin and the marks themselves affect the treatment discussion.[2]

For help understanding that assessment, read the Skin Journal guide to the consultation and clinician-reviewed treatment plan.

Why this matters before you book

Stretch marks are changes within the skin, not simply lines sitting on its surface. Their structure helps explain why treatment aims to make them less noticeable rather than restore completely unmarked skin.[2]

Choose treatment around an improvement you would value, not a promise of removal. If only complete clearance would feel worthwhile, the evidence does not support that expectation.[2]

How does fractional CO₂ treatment work?

Fractional means the laser treats small, separated areas rather than the entire skin surface. Think of a pattern of tiny treatment spots, with untreated skin between them. Treatment creates controlled injury intended to encourage skin remodelling, including changes in collagen, the skin's supporting protein.[1,2]

That process can improve texture, but it is not a skin eraser. A change in appearance does not mean the underlying stretch mark has disappeared.[1,2]

Why do stretch-mark results vary?

The research does not provide a reliable personal forecast. These are useful points to discuss during assessment:[1,2]

• Mark maturity: newer reddish marks and older pale marks have different features.
• Skin tone: pigment changes after treatment need particular attention in darker skin.
• Treatment settings: the approach used affects both the treatment response and recovery.
• Treatment course: studies use different schedules, making simple comparisons difficult.
• Assessment method: photographs, clinician ratings and patient opinions do not measure exactly the same thing.

These differences explain why a result from a study cannot become a promise for your skin.[2]

Who might not suit CO₂ resurfacing?

Someone who needs no downtime or expects complete removal is not a good match for the treatment's limitations. Fractional CO₂ treatment causes a healing response and can involve redness, swelling, crusting and discomfort.[1,2]

Darker skin is not an automatic exclusion. However, post-inflammatory hyperpigmentation—darker patches after inflammation—is an important risk to discuss.[1,2]

A personal assessment should also address your medical history, current skin condition and healing concerns. General research cannot establish your suitability remotely. Ask what would make the clinician recommend postponing or declining treatment.

What should you understand about recovery?

Common reported effects include redness, swelling, discomfort and crusting. Pigment changes can also occur, and laser resurfacing carries risks including infection and scarring.[1,2]

Ask for written aftercare instructions and a clear explanation of how to get help if healing concerns arise. Do not organise treatment around an assumed recovery deadline: the studies do not establish one universal timetable.[1,2]

What should you ask at a consultation?

Bring a short list rather than trying to remember everything on the spot:

• What improvement is realistic for these particular marks?
• Why does this approach suit my skin tone?
• What are the main reasons not to treat?
• What recovery should I plan around?
• What does the proposed treatment plan include?

You do not need to decide during the appointment. A useful consultation makes the trade-offs clearer, including the option of doing nothing.

FAQ

One last thing

Before agreeing to treatment, ask: What would count as a worthwhile improvement for me? That answer helps separate a realistic goal from an outcome the evidence cannot promise.
