CO2 laser resurfacing recovery timeline UK: what to expect
CO2 laser resurfacing is a powerful treatment that improves skin texture by creating controlled thermal injury in the skin, stimulating remodelling during healing. Because it is a resurfacing procedure, downtime is expected and varies by settings, skin type, treatment area and your individual healing response.
This guide explains typical recovery milestones, what “micro-crusting” looks like, how long redness or “pinkness” can last, and when it is usually safe to return to work, exercise and makeup. Your clinic’s instructions should always take priority, especially if you have medical conditions or a history of complications.
Who CO2 resurfacing can be suitable for
CO2 laser resurfacing is often considered for:
– Fine lines and wrinkles, especially around the mouth and eyes
– Sun damage and rough texture
– Enlarged pores and uneven tone
– Acne scarring (particularly rolling and boxcar scars, results vary)
– Certain benign lesions or textural irregularities, as advised by a clinician
Fractional CO2 treats a “fraction” of skin in a grid-like pattern, leaving bridges of untreated skin to speed healing. Fully ablative CO2 (less commonly used now) generally involves longer downtime and higher risk of side effects.
Who should avoid or postpone treatment
CO2 resurfacing may be unsuitable or delayed if you:
– Are pregnant or breastfeeding (typically postponed)
– Have an active skin infection, including cold sores in the area, impetigo or inflamed acne
– Have taken oral isotretinoin (Roaccutane) recently, your clinician will advise a safe interval
– Have a history of keloid scarring or poor wound healing
– Have uncontrolled diabetes, immune suppression, or take certain medications that affect healing
– Have very recent sun exposure, tanning, or cannot avoid UV during recovery
– Have darker skin tones where the risk of post-inflammatory hyperpigmentation is higher, assessment and settings matter
If you have a history of cold sores, prophylactic antiviral medication is commonly prescribed for peri-oral or full-face treatments.
Day-by-day recovery: Day 0 to Day 14
Recovery is commonly described in phases. The timings below are typical for fractional CO2 on the face, with moderate settings. Deeper settings and larger areas can extend recovery.
Day 0 (treatment day)
You may feel:
– Heat or a sunburn-like sensation for several hours
– Stinging or tightness as anaesthetic wears off
– Redness and swelling starting to build
What often helps:
– Frequent cooling as advised (not ice directly on skin unless directed)
– Keeping the skin well moisturised with an occlusive barrier ointment recommended by your clinic
– Sleeping with your head elevated to reduce swelling
Days 1 to 2
Common:
– Swelling peaks, especially around the eyes
– Redness deepens, skin feels tight
– Oozing or weeping can occur with deeper settings, more common after non-fractional or aggressive passes
Micro-crusting begins:
– “Micro-crusting” can look like tiny brown specks or a sandpaper texture. It is a normal part of resurfacing as microscopic columns of treated skin rise to the surface.
Do:
– Cleanse gently as instructed, often with sterile saline or a very gentle cleanser
– Pat dry, do not rub
– Reapply barrier ointment frequently to prevent cracking
Avoid:
– Picking or scraping crusts
– Hot showers directly on the face, steam rooms and saunas
Days 3 to 5
Common:
– Swelling starts to settle
– Skin darkens or bronzes in patches
– Peeling begins, often around the mouth and nose first
– Micro-crusting is more noticeable before it sheds
Do:
– Continue gentle cleansing, then barrier repair moisturiser or ointment
– Use clean pillowcases and avoid letting pets touch your face
Avoid:
– Active skincare (retinoids, acids, scrubs)
– Makeup, unless your clinician has specifically cleared mineral products for your stage of healing
Days 6 to 7
Common:
– Peeling and shedding accelerates
– Fresh new skin appears pink and sensitive
– Itchiness can occur as skin heals
This is a high-risk time for irritation:
– Rubbing, picking and “helping” flakes off can lead to prolonged redness, infection or scarring.
Days 8 to 10
Common:
– Most visible peeling has finished for many people
– Pinkness persists, often more obvious after a shower or exercise
– Skin may feel dry, tight or more reactive than usual
Often possible:
– Returning to work for many patients, depending on your job and how comfortable you feel with lingering redness
Days 11 to 14
Common:
– Skin texture feels smoother but remains pink
– Residual micro-crusting may still be present in smaller areas
– Mild sensitivity to skincare and sunlight continues
Often possible:
– Gradual return to normal skincare, but actives are usually still paused
– Some patients can wear makeup if the skin is fully healed, see the makeup section below
Redness and “pinkness” timeline: what is normal
Redness after CO2 resurfacing is expected because the skin is regenerating and new blood vessels are active in the healing process.
Typical redness milestones
- At 2 weeks: often pink, occasionally bright pink, with mild sensitivity. This can be normal, especially after deeper settings.
- At 4 to 6 weeks: pinkness usually fades gradually but may still be noticeable, particularly in fair skin.
- At 6 to 12 weeks: many people see continuing improvement in redness and texture. Some residual pinkness can persist, particularly after aggressive treatments or in more reactive skin.
Redness can be longer lasting in:
– Very fair skin types
– Deeper laser settings, multiple passes, or full-face treatment
– If the skin is irritated by early use of actives, heat, friction, or sun exposure
When to contact the clinic urgently
Seek clinical advice if you notice:
– Increasing pain after initial improvement
– Spreading redness with heat, swelling or tenderness
– Yellow crusting, pus, or a foul odour
– Fever or feeling unwell
– New blisters, rapidly worsening swelling, or eye symptoms
– A cold sore outbreak or clustered blisters
– Darkening patches that are increasing rather than settling, especially if you are prone to pigmentation
Early assessment can prevent small issues becoming prolonged recovery.
Aftercare essentials: what to use and what to avoid
Your clinician will provide a specific plan based on your settings and skin. The general principles are: gentle cleansing, moisture and barrier repair, infection prevention, and strict UV protection.
Cleansing
- Use tepid water
- Cleanse with sterile saline or a very gentle, fragrance-free cleanser as advised
- Pat dry with a clean, soft towel or gauze
Occlusive and barrier repair
Commonly recommended options include:
– Petrolatum-based ointments or clinic-provided healing balms in the early phase
– Simple, fragrance-free moisturisers once re-epithelialisation has occurred
Your goal is to keep skin comfortable and prevent cracks. Too-dry skin can split and prolong redness.
Sun protection (essential)
UV exposure after resurfacing increases the risk of post-inflammatory hyperpigmentation and prolonged redness.
– Avoid direct sun, especially in the first 2 to 4 weeks
– Wear a wide-brimmed hat outdoors
– Use a broad-spectrum SPF 50 when your clinician confirms it is safe to apply, often once the skin surface has healed
What to avoid, and for how long
Your clinician will personalise timing, but commonly avoided in early recovery:
– Retinoids and retinol: often paused for at least 2 to 4 weeks
– AHA/BHA acids and vitamin C acids: often paused for at least 2 to 4 weeks
– Scrubs, cleansing brushes and exfoliating cloths: avoid until fully healed
– Saunas, steam rooms and hot yoga: typically avoid for 2 weeks or more due to heat-induced redness
– Swimming pools and hot tubs: often avoid for at least 2 weeks due to infection and irritation risk
– High-intensity gym workouts: usually paused for several days to 2 weeks, see planning below
A simple aftercare checklist
- Clean hands before touching your face
- Do not pick peeling skin or micro-crusts
- Keep products minimal and fragrance-free
- Avoid heat, friction and sun
- Follow medication instructions exactly (antivirals, antibiotics or pain relief if prescribed)
When is it safe to wear makeup after CO2 resurfacing?
Makeup should only be applied once the skin surface has fully healed, meaning there are no open areas, weeping, or active peeling, and cleansing feels comfortable.
Typical guidance:
– Many patients: makeup may be possible around day 7 to 10 after fractional CO2, sometimes later with deeper settings.
– If still peeling or micro-crusting: wait. Applying makeup too early can irritate healing skin and increase the risk of infection.
Practical tips:
– Choose non-comedogenic, fragrance-free products
– Use clean brushes or sponges, avoid reusing old makeup applicators
– Remove makeup gently, do not double-cleanse aggressively
If you are unsure, bring your planned products to your review appointment for personalised advice.
Planning your treatment around work, exercise and events
Downtime is a key part of planning CO2 resurfacing.
Time off work
A realistic guide for many patients:
– Minimum social downtime: about 7 to 10 days for fractional CO2 on the face
– More cautious planning: 10 to 14 days, especially if your work is public-facing
Even after peeling stops, pinkness can remain and may be noticeable under certain lighting.
Exercise
Heat and sweating can worsen redness and irritation in early healing.
– Light walking is often fine within a few days, if comfortable
– Higher-intensity exercise is commonly delayed until the skin has healed on the surface, often 7 to 14 days
Weddings, photos and big events
For important events, consider:
– Planning treatment at least 6 to 12 weeks beforehand, as pinkness may persist and skin tone continues to settle
– If you are prone to pigmentation, a longer buffer can be wise
How settings affect downtime
Downtime varies widely:
– Lighter fractional settings: usually shorter peeling phase and faster return to makeup
– Deeper fractional settings or multiple passes: more swelling, longer peeling, longer pinkness
– Larger areas (full face) or adding neck: often extends recovery, neck can heal more slowly
Your clinician can balance settings with your goals and available downtime, but stronger treatments generally come with longer recovery and a higher risk of side effects.
At-a-glance recovery timeline
| Timepoint | Common skin changes | What patients often ask |
|---|---|---|
| Day 0 | Heat, redness begins | How to reduce discomfort |
| Days 1 to 2 | Swelling peaks, tightness, early micro-crusting | Is this normal swelling? |
| Days 3 to 5 | Bronzing, peeling starts, micro-crusting noticeable | Can I speed up peeling? |
| Days 6 to 7 | Peeling reduces, pink new skin | When can I go back to work? |
| Days 8 to 10 | Mostly healed surface, ongoing pinkness | When can I wear makeup? |
| Days 11 to 14 | Pinkness, sensitivity, dryness | When can I restart actives? |
| 6 to 12 weeks | Redness continues to fade | When will colour look normal? |
