Is CO2 Laser Good for Stretch Marks? A Complete Treatment Guide
Stretch marks are notoriously difficult to treat with creams alone — especially once they turn white, textured, or indented. Fractional CO2 laser is one of the few clinical treatments that can genuinely improve their appearance by stimulating collagen renewal deep within the skin.
So, is CO2 laser good for stretch marks? Yes — for the right candidate, it can meaningfully reduce texture, depth, and visibility. But it’s important to go in with clear expectations: CO2 laser improves stretch marks rather than erasing them completely.
This guide covers everything you need to know — how it works, realistic results, sessions needed, recovery, cost, and whether it’s right for your skin type.
What Are Stretch Marks?
Stretch marks form when skin stretches rapidly, disrupting the collagen and elastin fibres beneath the surface. The result is a visible scar — initially red, pink, or purple, and later fading to silver or white.
They most commonly appear on the:
- Stomach
- Thighs and hips
- Buttocks
- Breasts
- Upper arms
- Lower back
Their age, colour, and depth all influence how well they respond to treatment.
How Does CO2 Laser Work for Stretch Marks?
Fractional CO2 laser skin resurfacing delivers controlled micro-injuries to targeted zones of skin. This triggers the body’s natural healing response, stimulating new collagen and elastin production as the skin repairs itself.
Over time, treated skin becomes smoother, firmer, and more even in texture. For stretch marks specifically, this process can:
- Resurface uneven or raised texture
- Reduce the depth and width of stretch mark lines
- Improve skin firmness in the treated area
- Help blend stretch marks with the surrounding skin
The same collagen-stimulating process also makes CO2 laser effective for scar reduction treatment, as both stretch marks and scars share a similar skin structure.
What Results Can You Expect?
Treated stretch marks may appear:
- Smoother and softer to the touch
- Less deep or indented
- Less textured on the surface
- More blended with the surrounding skin
Results develop gradually over weeks to months as new collagen matures. Most people see continued improvement between sessions and for up to six months after their final treatment.
It’s important to set realistic expectations. CO2 laser is a significant improvement tool, not a complete removal method. The goal is for stretch marks to become far less noticeable — not invisible.
Is CO2 Laser Good for Old White Stretch Marks?
Older white stretch marks are more challenging to treat than newer red or purple marks, but the CO2 laser can still make a meaningful difference. Because the collagen in mature stretch marks has already settled, the laser works to remodel that tissue and improve surface texture.
For old white stretch marks, a course of treatments is usually recommended rather than a single session. Results take longer to develop but can still be significant.
CO2 Laser for Stomach Stretch Marks
The stomach is one of the most common treatment areas — particularly after pregnancy, significant weight changes, or body transformation. Stretch marks here often appear creased, loose, or uneven in texture, making them ideal candidates for CO2 resurfacing.
A practitioner will assess the depth of the stretch marks and the overall condition of the skin before recommending stretch mark treatment.
CO2 Laser for Stretch Marks After Pregnancy
Many people seek treatment for stretch marks after pregnancy, once they have finished breastfeeding and their skin has had time to stabilise. CO2 laser may help improve marks on the stomach, hips, thighs, or breasts.
Treatment is not suitable during pregnancy or while breastfeeding. A consultation will help determine the right time to start and the most appropriate treatment plan for your skin.
CO2 Laser vs Other Stretch Mark Treatments
| Treatment | Best For | Downtime | Key Consideration |
| CO2 Laser | Deeper texture, resurfacing, older marks | Higher | Strongest resurfacing option |
| Microneedling | Mild texture, collagen support | Lower | May require more sessions |
| RF Microneedling | Texture combined with skin tightening | Moderate | Good when laxity is also a concern |
| PRP | Skin repair and healing support | Minimal–moderate | Often combined with other treatments |

How Many Sessions Are Needed?
There is no universal number — it depends on the size of the treatment area, the severity of the stretch marks, and how your skin responds.
Some patients see noticeable improvement after one session. However, most benefit from a course of two to four treatments, spaced several weeks apart. Older, deeper, or more extensive stretch marks typically require more sessions.
Your practitioner will recommend a plan during your initial consultation.
What Happens During Treatment?
A typical CO2 laser appointment includes:
- Consultation and skin assessment — reviewing your medical history, goals, and suitability
- Patch test (if required for your skin type)
- Numbing cream applied 30–60 minutes before treatment
- Laser treatment on the selected area
- Aftercare instructions are provided before you leave
- Follow-up plan to monitor results and schedule further sessions if needed
Is CO2 Laser Painful?
Most patients describe the CO2 laser as feeling hot, prickly, or mildly uncomfortable. Numbing cream significantly reduces discomfort during the procedure. Afterwards, the treated skin typically feels warm and sensitive — similar to mild sunburn — for a short period.
Recovery Time After CO2 Laser for Stretch Marks
Recovery varies depending on treatment intensity and the area treated. Common after-effects include:
- Redness and warmth
- Swelling in the first 24–48 hours
- Dryness, tightness, and peeling
- Sensitivity to touch
- Temporary changes in pigmentation (more common in darker skin tones)
Most patients are presentable within five to seven days, though skin continues to heal beneath the surface for several weeks. Sun protection is essential during recovery and beyond.
Who Is Suitable for CO2 Laser Stretch Mark Treatment?
CO2 laser may be suitable if you:
- Have visible stretch marks you want to improve
- Are not currently pregnant or breastfeeding
- Are able to follow aftercare instructions carefully
- Have realistic expectations about results
- Are assessed as suitable following a professional consultation
It may not be appropriate if you have active skin infections, recent sun tanning, certain skin conditions, or are taking medications that affect healing or sensitivity.
Is CO2 Laser Safe for Darker Skin Tones?
CO2 laser carries a higher risk of post-inflammatory hyperpigmentation (PIH) in darker skin tones. This does not mean treatment is always unsuitable — but settings must be carefully adjusted, and a patch test is often essential.
A thorough consultation — including a CO2 laser patch test — is particularly important for Fitzpatrick skin types IV–VI.
How Much Does a CO2 Laser for Stretch Marks Cost?
Pricing depends on several factors:
- The size and number of areas treated
- The severity and extent of the stretch marks
- The number of sessions in your treatment plan
- Whether combination treatments are recommended
The most accurate way to get pricing is through a consultation, where a practitioner can assess your skin and provide a tailored quote.
