CO2 laser treatment is one of the most effective laser skin resurfacing procedures available today. People choose it to reduce wrinkles, acne scars, sun damage, enlarged pores, and uneven skin tone. However, one of the most common questions patients ask before committing to the procedure is: how long does CO2 laser last? How long will I see results for?
In this article, we’ll explore how CO2 laser treatment works, how long the results typically last, what factors affect longevity, and how you can maintain your results for years.
What Is CO2 Laser Treatment?
CO2 laser resurfacing uses carbon dioxide laser energy to remove damaged outer layers of skin while stimulating collagen production in deeper layers. This controlled injury triggers the body’s natural healing response, leading to smoother, firmer, and more youthful-looking skin.

There are two main types of CO2 laser treatments:
- Full field Ablative CO2 laser – Removes layers of skin for more dramatic results.
- Fractional CO2 laser – Targets microscopic areas, allowing faster healing with fewer side effects. Only a portion of the skin is resurfaced.
Both types are known for delivering long-lasting improvements compared to non-laser treatments.
How Long Does CO2 Laser Last?
When people ask how long does CO2 laser last, they may be referring to two things:
- How long the procedure itself takes
- How long the effects of the treatment last
Duration of the Procedure
A CO2 laser session usually lasts between 15 – 30 minutes, depending on:
- The size of the area treated
- The type of CO2 laser used
- The severity of skin concerns
- Whether fractional or full field
While the treatment itself is relatively short, the real value lies in the long-term results.
How Long Does CO2 Laser Results Last?
The most important question for most patients is how long do CO2 laser results last. The answer depends on several factors, but in general:
- Results can last 3 to 5 years
- In some cases, results may last even longer with proper skincare and maintenance
Because CO2 laser resurfacing stimulates collagen production, the skin continues to improve for several months after treatment. Many patients notice peak results around 3 to 6 months post-treatment, with benefits lasting for years.
Factors That Affect How Long CO2 Laser Results Last
While CO2 laser results are long-lasting, they are not permanent. Aging continues, and lifestyle habits play a major role in how long the results remain visible.
1. Age and Skin Condition
Younger patients or those with mild to moderate skin damage tend to enjoy longer-lasting results. Older skin may still benefit significantly, but natural aging can reduce longevity.
2. Sun Exposure
Excessive sun exposure is the number one reason CO2 laser results fade faster. UV damage breaks down collagen and accelerates aging.
3. Skincare Routine
Using medical-grade skincare products, especially retinoids, alpha hydroxy acids, antioxidants, and sunscreen, can significantly extend results.
4. Lifestyle Habits
Smoking, poor diet and dehydration all contribute to faster collagen breakdown.
5. Type of CO2 Laser Used
- Ablative CO2 lasers generally provide longer-lasting results
- Fractional CO2 lasers may require more sessions initially and maintenance sessions but they offer shorter recovery time
CO2 Laser vs Other Skin Treatments: Longevity Comparison
When considering how long CO2 laser results last, it helps to compare it with other popular treatments:
- Chemical peels: 1-2 weeks for light peels
- Microneedling: 1–3 months
- RF skin tightening: 3-6 months
- CO2 laser resurfacing: 3–5 years or more
This comparison highlights why CO2 laser is considered a gold standard for skin resurfacing.
Is CO2 Laser Permanent?
A common misconception is that CO2 laser results are permanent. While the improvement in skin quality is long-lasting, the aging process does not stop.
CO2 laser:
- Permanently removes damaged skin cells such as age spots
- Dramatically improves existing scars and wrinkles
- Does not prevent future aging or sun damage
That’s why maintenance and protection are essential to preserve results.
How to Make CO2 Laser Results Last Longer
If you’re investing in CO2 laser resurfacing, you’ll want to maximize the benefits. Here’s how:
1. Use Sunscreen Daily
Apply a broad-spectrum SPF 50 or higher every day, even indoors.
2. Follow Post-Treatment Instructions
Proper aftercare during healing plays a crucial role in final results.
3. Maintain a Healthy Skincare Routine
Incorporate:
- Retinol or prescription tretinoin, glycolic & salicylic acids
- Vitamin C serum
- Other exfoliating options
4. Consider Maintenance Treatments
Some patients benefit from:
- Light chemical peels
- Microneedling
- Non-ablative laser maintenance treatments (we offer laser toning)
5. Avoid Smoking
Smoking drastically reduces collagen and shortens the lifespan of CO2 laser results.
How Often Can You Get CO2 Laser?
Most patients only need one CO2 laser treatment every 1-5 years. In some cases:
- Fractional CO2 laser may be repeated every year
- Full ablative CO2 laser is usually done once every 2-5 years
A dermatologist or experienced laser practitioner (registered nurse) can recommend the best schedule based on your skin type and goals.
Final Thoughts: How Long Does CO2 Laser Really Last?
CO2 laser resurfacing is one of the most powerful treatments available for skin rejuvenation. While it’s not permanent, its long-lasting results make it a worthwhile investment for those seeking dramatic and lasting improvement in skin texture, tone, and firmness.
If you protect your skin, follow a good skincare routine, and maintain healthy lifestyle habits, you can enjoy the benefits of CO2 laser treatment for many years to come.
