Fractional CO₂ laser in Barcelona
Fractional CO₂ is the most powerful ablative technique in aesthetic medicine. Well indicated, it transforms skin quality. Poorly indicated, it is a source of avoidable complications.
What it is and when it makes sense
Fractional CO₂ generates microcolumns of heat that penetrate the dermis, triggering a repair response — new collagen, elastin, tissue reorganisation. "Fractional" means it treats skin in a pattern of columns separated by healthy tissue, accelerating recovery.
It makes sense in acne scars, perioral and periocular wrinkles, sun spots, dilated pores, mild laxity and in patients with accumulated sun damage seeking structural rejuvenation. It does not make sense in very dark skin without adapted protocol, or in patients who cannot afford a week of recovery.
My approach
CO₂ laser is not a button pressed the same for everyone. Parameters — density, depth, number of passes — adapt to each patient by phototype, indication and expected tolerance.
I work with reference medical equipment and safety-first protocols: always pre-treatment with depigmentants when there is hyperpigmentation risk, and always strict photoprotection plan for the following weeks. I prefer two gentler sessions to one aggressive one.
What the process looks like
In consultation I assess your skin, phototype, history and we decide strategy. It may require topical pre-treatment for 2–4 weeks before the session.
Session is done with strong topical anaesthetic and lasts 45 minutes to 1 hour. First 5–7 days are recovery: intense redness, sunburn sensation, fine peeling. New skin is visible by day 7–10.
What to expect
First result at 1 month: more uniform skin, finer pores, softened superficial wrinkles. Full result — new collagen formation — reaches at 3 months and continues improving up to 6.
For acne scars 2–3 sessions spaced every 2–3 months are typical. For global rejuvenation, one annual maintenance session usually suffices. The result is permanent in that new collagen persists for years, but skin continues to age.
When I DO NOT recommend CO₂ laser
In summer or with recent sun exposure. Tanned skin has higher risk of post-inflammatory hyperpigmentation. I prefer to schedule in autumn-winter.
In patients on isotretinoin (Roaccutane) in the past 6 months, with active herpes labialis without prophylaxis, or in pregnancy/breastfeeding. When the patient cannot accept 5–7 days of "marked" appearance, I offer less invasive alternatives.
Frequently asked questions
How many recovery days does CO₂ laser need?
5 to 7 days of social recovery: redness, sunburn sensation and fine peeling. New skin is fully visible by day 10.
Can CO₂ laser be done in summer?
I do not recommend it. Sun-exposed skin has higher risk of post-inflammatory hyperpigmentation. I schedule these sessions preferentially in autumn-winter.
Does CO₂ laser work on acne scars?
Yes, it is one of the best indications. 2–3 sessions spaced every 2–3 months are typical, with cumulative improvements in texture, depth and colour.
How many sessions do I need?
Depends on the goal: 1 session for general rejuvenation with annual retouch; 2–3 sessions for acne scars or advanced sun damage. We define it in the assessment.
