Fraxel and CO2 lasers are both popular choices for addressing various skin concerns and achieving a more youthful appearance. However, while they share the goal of skin rejuvenation and resurfacing, they differ significantly in their technology and approach. Understanding the difference between Fraxel lasers and CO2 lasers is essential for making an informed decision about which treatment is right for you.
Is Fraxel a CO2 Laser?
This is a common question and a frequent point of confusion for many people. However, Fraxel is not a CO2 laser. While both fall under the category of lasers used for skin resurfacing, they represent distinct technologies with different mechanisms of action, recovery processes, and overall treatment experiences.
The Differences Between Fraxel and CO2 Laser
Let’s explore the key differences between these two laser treatments:
1. Technology
Fraxel lasers use a fractional approach, creating tiny micro-injuries in the skin while leaving the surrounding tissue intact. Fraxel lasers also utilise different wavelengths (typically 1550 nm and 1927 nm) to target different layers of the skin, addressing a wider range of concerns. This versatility makes Fraxel a popular choice for those seeking comprehensive skin rejuvenation.
Fraxel lasers also promote potentially faster healing and encourage collagen production, leading to skin renewal and improvement in texture and tone. This is why Fraxel lasers are often the treatment of choice for those with busy lifestyles.
When it comes to the technology used for CO2 lasers, there are two main categories:
- Traditional ablative lasers: Remove the entire top layer of skin, leading to more dramatic results but also a longer recovery time.
- Fractional CO2 lasers: Deliver the laser energy in a fractionated pattern, creating microscopic columns of treated skin surrounded by untreated skin.
While both Fraxel and fractional CO2 lasers fall under the category of fractional lasers, they differ in their wavelength and the intensity of their energy delivery. Fraxel lasers typically use erbium or thulium lasers, which are less aggressive and have a shorter downtime than CO2 lasers. Fractional CO2 lasers, on the other hand, utilise a more powerful CO2 laser that penetrates deeper into the skin, potentially resulting in more dramatic results and a longer recovery period.
2. Effectiveness
Fraxel lasers are a popular choice for overall skin resurfacing and improving skin texture as they stimulate collagen production. These lasers may also be used for addressing a range of skin concerns, including:
- Acne scars
- Fine lines and wrinkles
- Uneven or dull skin tone
- Light to moderate sun damage
CO2 lasers are particularly effective for addressing skin concerns, such as:
- Deeper wrinkles
- More serious sun damage
- Age spots
3. Procedure and Recovery
Fraxel laser treatment is generally considered non-invasive, with minimal discomfort and a relatively quick recovery time. Most patients may resume their usual activities within a day or two. During the session, a topical numbing cream may be applied to minimise any discomfort. Afterwards, patients may experience some redness and mild swelling, which usually subsides within a few days.
Ablative CO2 laser treatment, on the other hand, is more in-depth and typically requires some form of anaesthesia. The recovery period is longer compared to Fraxel, and patients may need to take some time off from their usual activities to allow their skin to heal. Following the procedure, patients may expect more redness, swelling, and discomfort, lasting several days to a week.
4. Potential Side Effects and Risks
The potential side effects of Fraxel laser treatment include temporary redness, swelling, and mild discomfort. The risk of complications is generally low, and side effects are usually mild and temporary. In rare cases, patients may experience temporary changes in skin pigmentation.
Meanwhile, CO2 laser treatment carries a higher risk of side effects, including redness, swelling, pain, itching, and changes in skin pigmentation. While these side effects are usually temporary, they may be more pronounced compared to Fraxel.
5. Skin Type Suitability
Fraxel lasers are often recommended for individuals with sensitive skin or lighter skin tones, as they are less likely to cause pigmentation changes, In contrast, CO2 lasers may be more suitable for individuals with oilier or thicker skin, as they can penetrate deeper layers. However, they may not be the best choice for darker skin tones due to the increased risk of pigmentation changes.
Ultimately, the suitability of each skin resurfacing treatment for your specific skin concerns is best determined by a qualified professional like Dr Gerard Ee. They can assess your skin’s condition and recommend the most appropriate course of action.
6. Treatment Sessions and Intervals
Fraxel laser treatment typically requires multiple sessions to achieve optimal results, usually 3-5 sessions spaced 2-4 weeks apart. This allows for gradual skin resurfacing and minimises downtime, which is usually only a few days of redness and swelling.
CO2 laser treatment, on the other hand, may require fewer sessions, typically 1-3 for ablative and 3-8 for fractional CO2, but with a longer recovery period. Downtime for ablative CO2 lasers could be 1-2 weeks, while fractional CO2 lasers have a downtime of around 3-7 days, depending on the intensity of the treatment.
The exact number of sessions and the intervals between them will vary depending on your needs and the laser used. Hence, it’s important to consult with a qualified professional to determine the appropriate treatment schedule and intervals for your specific needs.
7. Longevity and Maintenance
The longevity of results for both Fraxel and CO2 lasers can vary depending on individual factors. Generally, skin resurfacing with both lasers can last several months to years. For instance, when discussing Fraxel vs. CO2 laser for acne scars, the results could last several years, although the improvement may gradually diminish over time due to the natural ageing process. Hence, touch-up treatments might be needed to maintain the initial level of improvement.
Fraxel Laser vs. CO2 Laser: A Summary
| Feature | Fraxel Laser | CO2 Laser |
| Technology | Fractional | Ablative (Traditional) / Fractional |
| Mechanism | Creates micro-injuries, leaving the surrounding tissue intact | Removes top layer of skin (ablative) / Creates microscopic columns of treated skin (fractional) |
| Concerns Addressed |
|
|
| Procedure | Non-invasive, minimal discomfort | More invasive, may require anaesthesia |
| Recovery | Faster (1-2 days) | Longer (1-2 weeks for ablative, 3-7 days for fractional) |
| Side Effects | Redness, swelling, discomfort (typically mild and temporary) | Redness, swelling, pain, itching, pigmentation changes (can be more pronounced) |
| Skin Type Suitability | Sensitive skin, lighter skin tones | Oilier skin, thicker skin (may not be suitable for darker skin tones) |
| Sessions & Intervals | 3-5 sessions, 2-4 weeks apart | 1-3 sessions (ablative), 3-8 sessions (fractional); longer intervals between sessions |
| Longevity | Several months to years | Several months to years |
Is Fraxel Laser Worth It?
