“What’s the difference between CO₂ laser and Er:YAG laser resurfacing?”
“Which is better for my skin concerns like scars, wrinkles, and texture?”

CO₂ laser resurfacing is a fractional ablative laser that delivers deep thermal energy to both remove skin layers and stimulate strong collagen remodeling.
It combines vaporization of tissue with heat damage to trigger regeneration from deep within the dermis.
✔ Best For:
- Moderate to severe acne scars
- Deep wrinkles and lines
- Significant texture irregularities
- Thickened or sun-damaged skin
- Patients seeking dramatic resurfacing
✔ Advantages:
- Strong collagen stimulation
- Deep and lasting resurfacing effects
- Excellent for deep scars and folds
- Long-term improvement
✔ Downtime:
- 5–10+ days of redness, swelling
- Peeling, crusting, and flaking
- Possible scab formation
- Strict sun avoidance required
CO₂ is ideal for patients who need powerful skin renewal and are comfortable with extended recovery.
What Is Er:YAG Laser Resurfacing?

Er:YAG laser resurfacing is also an ablative fractional laser but uses a wavelength that is absorbed more efficiently by water in the skin, resulting in less thermal damage and gentler tissue ablation.
It precisely removes superficial layers with minimal heat spread into deeper tissue.
✔ Best For:
- Mild to moderate acne scars
- Fine lines and shallow wrinkles
- Uneven texture
- Patients wanting effective resurfacing with shorter recovery
✔ Advantages:
- More precise superficial ablation
- Less thermal injury than CO₂
- Shorter downtime
- Lower risk of prolonged inflammation
✔ Downtime:
- 3–7 days of redness and peeling
- Light swelling
- Makeup possible sooner than CO₂
Er:YAG is ideal for patients wanting resurfacing benefits with milder recovery.
Which Laser Is Better?
The choice between CO₂ and Er:YAG resurfacing depends on how deep the issue is, desired strength of result, and downtime tolerance.
- CO₂ laser delivers stronger, deeper resurfacing, making it more suitable for severe acne scars, deep wrinkles, and significant texture problems.
- Er:YAG laser provides gentler ablation with shorter downtime, well suited for mild to moderate concerns and patients who want quicker recovery.
In many clinics in Seoul, dermatologists assess individual skin type, scar depth, and goals before recommending the ideal laser.
Can You Combine CO₂ and Er:YAG?
Yes.
In some treatment plans, fractional CO₂ may be used for deep resurfacing, followed by Er:YAG for surface refinement once initial healing has occurred.
This staged strategy maximizes overall improvement while managing downtime and risk.
Who Should Choose CO₂ Laser Resurfacing?
- Moderate to severe acne scars
- Deep wrinkles
- Thickened or photo-damaged skin
- Patients wanting dramatic results
- Those willing to allow longer recovery
Who Should Choose Er:YAG Laser Resurfacing?
- Mild to moderate acne scars
- Fine lines and superficial texture irregularities
- Patients wanting shorter downtime
- Sensitive or pigmentation-prone skin
