When researching laser skin rejuvenation treatments, many patients ask whether they should choose a CO₂ laser or a Frax laser.
Both treatments can improve skin quality, reduce signs of ageing, and stimulate collagen production. However, they work differently and are suited to different concerns, recovery times, and treatment goals.
What Is a CO₂ Laser?
CO₂ laser resurfacing is considered a more intensive skin rejuvenation treatment.
The laser removes microscopic layers of damaged skin while stimulating new collagen production. This can be particularly effective for:
- Deep wrinkles
- Advanced sun damage
- Significant skin texture concerns
- Acne scars
- Skin resurfacing
Because CO₂ laser treatments are more aggressive, they typically involve longer downtime, redness, peeling, and a more extended recovery period.
What Is Frax Laser?
Frax Laser by Candela is a fractional laser treatment designed to improve skin quality while minimising downtime.
Instead of fully resurfacing the skin, Frax creates controlled microscopic treatment zones that stimulate the skin's natural healing response and collagen production.
Frax is commonly used to improve:
- Pigmentation and sun damage
- Uneven skin tone
- Fine lines
- Enlarged pores
- Mild to moderate acne scars
- Overall skin texture and quality
Many patients choose Frax because it delivers noticeable skin rejuvenation while allowing them to return to normal activities much sooner than with traditional resurfacing treatments.
CO₂ Laser vs Frax: Key Differences
Downtime
CO₂ laser treatments generally require a longer recovery period with more redness and peeling.
Frax treatments typically involve significantly less downtime and a faster return to daily activities.
Comfort
Most patients find Frax treatments more comfortable than traditional CO₂ resurfacing procedures.
Treatment Goals
CO₂ laser may be more suitable for severe skin ageing, deeper wrinkles, and significant scarring.
Frax is often chosen for patients seeking skin rejuvenation, collagen stimulation, pigmentation correction, and overall skin improvement with a less intensive recovery.
Which Laser Treatment Is Right for You?
The best treatment depends on your skin condition, goals, lifestyle, and recovery expectations.
During a consultation, a qualified medical professional can assess your skin and recommend the most appropriate treatment plan based on your individual needs.
