CO₂ Laser Resurfacing: Benefits, Downtime, Recovery and Aftercare
CO₂ laser resurfacing is one of the most effective advanced skin treatments for improving skin texture, fine lines, acne scarring, pigmentation irregularities and overall skin quality. It works by using controlled laser energy to resurface the upper layers of the skin while stimulating collagen production deeper within the skin.
At M.E. Aesthetics, CO₂ laser is used carefully and clinically, with treatment intensity tailored to your skin, concerns, healing ability and desired downtime. Some clients may be suitable for a lighter fractional treatment with a shorter recovery, while others may benefit from a deeper, more intensive resurfacing treatment with longer downtime but potentially more visible improvement.
What is CO₂ laser?
CO₂ laser is an ablative resurfacing treatment. This means it creates controlled injury to the skin to encourage healing, renewal and collagen remodelling. The treatment removes damaged surface skin while encouraging the body to form fresher, smoother and healthier-looking skin.
CO₂ laser can be used in different strengths. This is important because not every client needs or wants the same level of treatment. A lighter treatment may focus on glow, mild texture and early lines, while a deeper treatment may be chosen for more significant wrinkles, acne scarring, sun damage or skin resurfacing.
Because this is a clinical resurfacing treatment, some visible healing is expected. This may include redness, swelling, heat, dryness, crusting, peeling and temporary sensitivity.
What can CO₂ laser improve?
CO₂ laser may help to improve:
• Skin texture
• Fine lines and wrinkles
• Acne scarring
• Enlarged pores and roughness
• Pigmentation irregularities
• Sun damage
• Crepey skin
• Uneven skin tone
• Overall skin quality
• Collagen production
The aim is improvement, not perfection. Some skin concerns, especially deeper acne scarring, severe sun damage or deeper wrinkles, may improve significantly but may not fully disappear.
Less intensive vs more intensive CO₂ laser
One of the most important things to understand is that CO₂ laser can be performed at different depths and strengths.
Less intensive fractional CO₂ laser
This option is usually best for clients wanting improvement in mild texture, early fine lines, mild pigmentation, enlarged pores or general skin quality.
It usually has a shorter downtime and a more manageable healing process. The skin may feel hot, tight and rough, with a fine dotted or grid-like pattern. Peeling usually starts after a few days and most visible shedding is often complete within around 5 to 7 days.
This option may be more suitable if you want improvement but cannot commit to longer downtime.
More intensive deeper CO₂ laser
This option may be used for deeper wrinkles, more significant acne scarring, more advanced texture concerns, heavier sun damage or more intensive resurfacing.
The recovery is more involved. You may experience more heat, swelling, oozing, bronzing, crusting, sheet-like peeling and longer-lasting redness. Social downtime is usually longer, commonly around 10 to 14 days, although redness or pinkness can continue for several weeks.
Deeper treatment can offer more significant resurfacing, but it also carries a higher level of downtime and requires stricter aftercare.
Who is CO₂ laser most suitable for?
CO₂ laser may be suitable if you:
• Have uneven texture or rough skin
• Have acne scarring or post-acne texture changes
• Have fine lines or wrinkles
• Have sun damage or pigmentation irregularities
• Want stronger skin resurfacing than a facial, peel or microneedling
• Understand the downtime and healing process
• Are able to follow aftercare carefully
• Are realistic that results are gradual and vary between clients
CO₂ laser is best suited to clients who are prepared for a visible recovery period and who can avoid sun exposure, picking and active skincare during healing.
Who may not be suitable for CO₂ laser?
CO₂ laser may not be suitable, or treatment may need to be delayed, if you:
• Are pregnant or breastfeeding
• Have an active cold sore or feel one starting
• Have an active skin infection
• Have open wounds, broken skin or unhealed skin
• Have recent sunburn or significant recent tanning
• Have a history of poor wound healing
• Have a history of keloid or hypertrophic scarring
• Have uncontrolled diabetes or a condition affecting healing
• Are immunosuppressed or undergoing cancer treatment
• Have used oral isotretinoin or Roaccutane recently
• Have had recent facial surgery, trauma, burns or radiotherapy to the area
• Cannot follow the aftercare or avoid sun exposure
• Have unrealistic expectations about results
Clients with darker skin tones, melasma or pigmentation-prone skin may require extra caution because post-inflammatory pigmentation changes can occur after laser resurfacing.
What to expect during treatment
Before treatment, your practitioner will assess your skin, medical history, concerns, previous treatments, pigmentation risk and healing suitability. Clinical photographs may be taken as part of your medical record.
The skin is cleansed and prepared. Depending on the treatment area and intensity, topical numbing cream or other comfort measures may be used. During treatment, you may feel heat, prickling, stinging or a warm snapping sensation.
After treatment, the skin will feel hot and sensitive, similar to sunburn. The recovery process then begins.
Recovery timeline for less intensive CO₂ laser
Days 1 to 2
The skin may feel hot, tight, swollen and sensitive. It may look red or flushed, similar to sunburn. A fine grid pattern or tiny dark dots may appear.
Days 3 to 5
The skin may feel dry, rough and sandpaper-like. Flaking and peeling often begin around the mouth and nose before spreading. Do not pick or pull the skin.
Days 6 to 7
Most peeling is usually complete. The skin may look fresh, pink and slightly flushed. Makeup may usually be worn once the skin is fully closed and your practitioner confirms it is suitable.
Week 2 onwards
Pinkness continues to settle. The skin may look brighter and smoother, but results continue developing over the following weeks.
Recovery timeline for more intensive CO₂ laser
Days 1 to 3
The skin may feel very hot, swollen and tender. Oozing or weeping of clear or amber fluid can occur. Swelling may be more noticeable around the eyes if the upper face has been treated.
Days 4 to 7
The skin may look bronzed, brown, crusted or tight. Peeling can be heavier and may come away in larger sheets. Itching is common, but the skin must not be scratched or picked.
Days 8 to 10+
Peeling usually finishes and fresh pink or red skin appears underneath. The skin barrier is stronger but still sensitive.
Weeks 2 to 6+
Redness or pinkness can persist for several weeks, especially after deeper treatment. This is a normal part of healing and collagen stimulation.
How long is the downtime?
Downtime depends on the treatment strength.
As a general guide:
• Less intensive fractional CO₂: around 5 to 7 days social downtime
• More intensive deeper CO₂: around 10 to 14 days social downtime
• Pinkness may continue for days to weeks
• Deeper treatments may have redness for several weeks or longer
• Collagen remodelling continues for months
CO₂ laser healing is not just about when peeling stops. The skin may look healed on the surface before it is fully settled underneath.
When will I see results?
Some improvement may be visible once peeling has finished, but the main results develop gradually.
You may notice improvement in skin texture and brightness first. Collagen remodelling continues over time, so results usually continue improving over 4 to 12 weeks and may continue developing for up to 6 months.
More than one treatment may be required, especially for acne scarring, deeper lines, significant pigmentation or more advanced texture concerns.
Beforecare advice
Before CO₂ laser, please follow your personalised practitioner advice. General guidance may include:
• Avoid sun exposure, sunbeds and tanning before treatment
• Do not attend with sunburn or active tan
• Avoid fake tan on the treatment area
• Stop retinoids, exfoliating acids and strong active skincare as advised
• Inform the clinic of any cold sore history
• Tell us if you develop illness, infection, broken skin or a rash
• Avoid alcohol for 24 to 48 hours before treatment where possible
• Avoid non-essential blood-thinning supplements if advised
• Do not stop prescribed medication without medical advice
• Arrive with clean skin and no heavy makeup
• Avoid booking treatment too close to holidays, weddings or important events
If you have a history of cold sores, antiviral medication may be recommended before and after treatment to reduce the risk of a flare-up.
Aftercare advice
Aftercare is one of the most important parts of CO₂ laser treatment. Poor aftercare can increase the risk of infection, pigmentation changes, delayed healing and scarring.
Core recovery rules
• Keep the skin moist
• Do not let the treated area dry out or form a hard crust
• Do not pick, scratch or peel the skin
• Avoid direct sun exposure
• Wash your hands before touching your face
• Use only the products advised by your practitioner
• Avoid active skincare until you are told it is safe
• Avoid heat, sweating, saunas, steam rooms and intense exercise during early healing
Your clinic aftercare may include vinegar soaks and Aqueous Cream or a specific recovery balm. The aim is to keep the skin clean, calm, moist and protected while it heals.
Skincare after CO₂ laser
Healing stage
Until peeling is fully complete, keep skincare very simple. Use only the products advised by your practitioner. Avoid cleansers, makeup, acids, retinoids, vitamin C, exfoliants, scrubs, fragranced products and strong active ingredients unless specifically instructed.
Once peeling has finished
Once the skin is closed and shedding has finished, you may usually introduce a very gentle non-foaming cleanser, a bland moisturiser and mineral SPF.
Mineral sunscreen is often preferred at this stage because fresh skin may sting with chemical sunscreens. Sun protection is essential because new skin is more vulnerable to pigmentation.
Two weeks onwards
If the skin is calm, comfortable and no longer stinging, gentle ingredients such as niacinamide or mild vitamin C derivatives may be introduced slowly if advised.
Four to six weeks onwards
Stronger actives such as retinoids, tretinoin, glycolic acid, salicylic acid, exfoliating acids, scrubs or cleansing brushes should usually wait until the skin has fully recovered and your practitioner confirms it is safe.
What is normal after CO₂ laser?
It is normal to experience:
• Heat
• Redness
• Swelling
• Tightness
• Dryness
• Itching
• Rough texture
• Bronzing
• Grid marks
• Peeling
• Temporary sensitivity
• Pink fresh skin after shedding
Small breakouts or tiny white bumps can occur after laser resurfacing, particularly when thicker healing creams are used.
When should I contact the clinic?
Please contact the clinic if you experience:
• Severe or worsening pain
• Increasing redness, heat or swelling
• Yellow or green discharge
• Fever or feeling unwell
• Cold sore blisters
• Skin that remains raw, bleeding or open longer than expected
• Blistering, scabbing or dark discolouration
• Any symptom that feels unusual or concerning
We would always rather you contact us early so we can advise you properly.
Is CO₂ laser safe?
CO₂ laser can be very effective when performed by an appropriately trained practitioner with careful patient selection, appropriate settings and good aftercare. However, because it is an ablative resurfacing treatment, it does carry risks.
Common side effects include redness, swelling, heat, peeling, tightness, itching and temporary sensitivity. Less common risks include infection, cold sore flare-up, prolonged redness and pigmentation changes. Rare risks include scarring, burns, permanent pigment change or texture change.
This is why consultation, medical screening and aftercare are so important.
Final thoughts
CO₂ laser is a powerful skin resurfacing treatment for clients wanting improvement in texture, fine lines, acne scarring, pigmentation and overall skin quality.
The key is choosing the right intensity for your skin and goals. A lighter fractional CO₂ treatment may offer a shorter recovery with more subtle improvement, while deeper CO₂ resurfacing may give more significant change but requires longer downtime and stricter aftercare.
At M.E. Aesthetics, we will guide you through the most suitable option for your skin, explain the recovery honestly, and support you with clear aftercare so you know exactly what to expect.
CO₂ laser is not a quick facial. It is a clinical resurfacing treatment. But for the right client, with realistic expectations and careful aftercare, it can be an excellent option for smoother, fresher and healthier-looking skin.
