CO₂ Fractional Laser Treatment Aftercare Guide
What to Expect After Treatment
Following your fractional CO₂ laser treatment, your skin has undergone controlled micro-injuries to stimulate collagen production and skin renewal. The treated area will appear red and may feel warm, similar to sunburn. Small grid-like marks from the laser pattern will be visible initially but will fade during the healing process.
Timeline of Healing
Understanding your daily recovery roadmap.
Days 0-2
Redness, warmth, mild swelling, and sensitivity.
Days 3-5
Skin may develop a bronze appearance and feel rough or gritty; mild peeling may begin.
Days 5-7
Peeling continues; new pink skin emerges underneath.
Days 7-14
Redness gradually subsides; skin texture continues to improve.
Weeks 2-12
Continued collagen remodelling; progressive improvement in skin quality.
Phase 1: Immediate Care (First 24-48 Hours)
Cooling and Comfort
- Apply cold compresses or ice packs wrapped in clean gauze for 15-20 minutes every 1-2 hours while awake to reduce swelling and discomfort.
- Keep your head elevated when sleeping to minimise swelling.
- Take paracetamol or ibuprofen as directed for discomfort if needed.
Skin Protection
- Keep the treated area constantly moist with a thin layer of healing ointment (Aquaphor or as provided by the clinic).
- Do not allow the skin to dry out—reapply ointment every 2-3 hours.
- Avoid touching your face except when applying products with freshly washed hands.
Phase 2: Days 1-7 (Active Healing Phase)
Cleansing Guidelines
Begin gentle cleansing twice daily from Day 1 using lukewarm water and a mild, fragrance-free cleanser (Cetaphil or as recommended).
- Pat skin gently with fingertips only—do not scrub or use washcloths.
- Rinse thoroughly and pat dry with a clean towel.
- Men should not shave the treated area for 7-10 days.
Optional Vinegar Soaks (Days 1-5)
Mix 1 teaspoon white vinegar with 1 cup of cool water. Soak clean gauze in the solution and apply to treated areas for 10-15 minutes.
- Provides gentle antimicrobial action.
- Helps dissolve crusting and soothes discomfort.
- May be performed 3-4 times daily after cleansing.
Moisturising & Protection
Continue applying healing ointment generously after each cleanse and soak.
- Do not pick at any crusts or peeling skin—allow them to shed naturally.
- Picking can lead to scarring, permanent pigment issues, and infection.
Phase 3: Days 7-14 (Transition Phase)
When New Skin Appears
Once areas have re-epithelialised (smooth and pink, no longer raw), you may transition from heavy ointment to a gentle, fragrance-free moisturiser.
- Continue moisturising frequently (every 2-3 hours) as new skin can be very dry.
- Some areas may heal faster than others—continue ointment on any areas that remain raw or weeping.
Critical Sun Protection
Once skin has re-epithelialised, apply a broad-spectrum mineral sunscreen daily.
- Use SPF 30 minimum (SPF 50 preferred) every morning.
- Reapply every 2 hours if outdoors.
- Wear a wide-brimmed hat and avoid direct sun exposure entirely.
Phase 4: Weeks 2-12 (Recovery & Results)
Skincare Rules
- You may resume makeup application once skin is fully healed (typically 7-10 days) and with your practitioner's approval.
- Avoid active ingredients (retinoids, vitamin C, AHAs, BHAs, exfoliants) until cleared (typically 4-6 weeks).
- Continue daily gentle cleansing, moisturizing, and sunscreen use.
Activity Restrictions
- Avoid strenuous exercise for 7-10 days to prevent excessive sweating and heat.
- Avoid swimming pools, hot tubs, saunas, and steam rooms for 2 weeks.
- Avoid excessive heat exposure (hot showers, hair dryers on high heat).
Important Restrictions
Failing to adhere to these restrictions can severely compromise your clinical results.
Strictly Avoid for 2-4 Weeks:
- Direct sun exposure: Essential to prevent post-inflammatory hyperpigmentation (PIH).
- Smoking and alcohol consumption: Nicotine and alcohol dramatically delay optimal tissue recovery.
- Harsh skincare products or treatments: Avoid clinical peels, scrubs, or microdermabrasion.
- Facial hair removal: Avoid facial waxing, threading, or chemical depilatories.
- Dusty or dirty environments: Minimise infection risks from micro-particles.
🚨 Signs Requiring Medical Attention
Contact Dr Brad's clinic immediately if you experience:
- Severe or worsening pain not controlled by over-the-counter pain relief.
- Increased redness, warmth, swelling, or tenderness after the first 3 days.
- Yellow or green discharge, or pus.
- Fever or flu-like symptoms.
- Blistering or crusting that appears infected.
- Development of cold sores or an unusual rash.
Clinical Prophylaxis & Medications
Antiviral Prophylaxis
If prescribed: Start acyclovir 2 days before treatment and continue for 7 days total to prevent viral skin infections, especially in patients with a history of cold sores.
Antibiotic Prophylaxis
If prescribed: Begin taking the morning of your procedure and continue as directed (typically 5-7 days) to reduce risk of bacterial infection.
Optimising Your Results
Long-term Care
- Maintain a consistent skincare routine with medical-grade products.
- Use sunscreen daily, even when not in direct sunlight.
- Stay well hydrated and maintain a healthy diet rich in vitamins and antioxidants.
- Avoid smoking, which damages collagen and impairs healing.
- Consider maintenance treatments as recommended by Dr Brad.
Expected Results
Most patients notice improvement within 2-4 weeks, with continued enhancement over 3-6 months as collagen remodelling continues.
Final results typically become apparent at 3-6 months post-treatment.
General Advice for All CO₂ Laser Treatments
Lifestyle Factors That Support Healing
Nutrition & Hydration
- Eat a balanced diet rich in protein, vitamins A, C, and E, and zinc.
- Stay well hydrated (minimum 2 litres of water daily).
- Avoid alcohol for at least 7-14 days post-treatment (impairs healing).
Smoking & Oxygenation
- Do not smoke during the healing period.
- Smoking dramatically impairs wound healing and collagen formation.
- Significantly increases risk of infection and poor scarring.
Sleep Hygiene
- Aim for 7-9 hours of quality sleep nightly.
- Sleep with your head elevated if recovering from a facial treatment.
- Use clean pillowcases daily during the healing phase.
- Minimise stress—stress hormones can actively impair recovery. Rest and relax during your recovery period.
☀️ Sun Protection Cannot Be Overstated
Why Sun Protection is Critical:
UV exposure on healing or recently healed skin can cause permanent hyperpigmentation (dark marks). This is especially important for patients with darker skin types (Fitzpatrick III-VI). Post-inflammatory hyperpigmentation can take months to years to fade if it occurs.
How to Protect Your Skin:
- Use SPF 50 broad-spectrum mineral sunscreen daily.
- Reapply every 2 hours when outdoors.
- Wear protective clothing, wide-brimmed hats, and sunglasses.
- Seek shade and avoid sun exposure between 10am-4pm.
- Use sun protection even on cloudy days and indoors near windows.

- Do not pick, scratch, or interfere with scabs or peeling skin.
- Protect from sun exposure rigorously.
- Watch for signs of infection and seek help promptly.
