CO2 laser treatments are popular for improving skin texture, reducing wrinkles, and treating scars. However, proper aftercare is crucial to achieve the best results and minimize potential side effects. Below is a comprehensive guide for CO2 laser aftercare.
1. Immediately After Treatment (First 24–48 Hours)
Sensation: Expect mild to moderate heat, redness, and swelling — similar to a sunburn.
Cooling: Apply a clean, cool compress or gel pack (wrapped in a soft cloth) for 10–15 minutes each hour as needed.
Cleansing: Gently cleanse the area 2–3 times daily using a mild, non-foaming water based cleanser.
Moisturising: Keep the skin continuously hydrated with a thin layer of Aloe Vera, or Cream Provided. Do not allow the skin to dry out or form crusts.
No touching or picking: Avoid scratching, rubbing, or peeling any flaking skin — this can lead to scarring or pigmentation.
2. Expected Reactions
Timeframe | What You May Notice |
Day 1–2 | Redness, mild swelling, and warmth. Possible pinpoint oozing or tightness. |
Day 3–5 | Skin feels dry or “sandpaper-like,” with light flaking or bronzing. |
Day 5–7 | Peeling reveals pink, fresh skin. Redness may persist for up to 1–2 weeks. |
Week 2–4 | Gradual fading of redness; smoother, brighter skin texture. |
3. Care Routine (Days 3–7)
Continue gentle cleansing and moisturizing 2–3 times per day.
If the skin feels tight, apply your healing ointment more often.
Avoid using makeup until the skin surface has completely healed (no open areas or peeling).
Sleep on your back with your head slightly elevated to reduce swelling.
4. Sun Protection (Absolutely Essential)
Once the skin has healed (no crusting or oozing), apply broad-spectrum SPF 50+ daily — even indoors.
Reapply every 2–3 hours if outdoors.
Avoid direct sunlight for at least 4 weeks post-treatment.
Wear a wide-brimmed hat and seek shade whenever possible.
Sun exposure during healing is the most common cause of pigmentation changes.
5. Avoid Until Fully Healed
Hot showers, saunas, swimming pools, or spas
Strenuous exercise for 3–5 days
Alcohol-based or exfoliating products
Retinoids, AHA/BHA acids, or vitamin C serums for 2–4 weeks
Makeup until new skin has fully formed
6. Medications
You may take paracetamol for discomfort.
Avoid ibuprofen or aspirin for 48 hours (they can increase bleeding).
Avoid Antihistamines they can reduce your collagen production.
7. When to Contact Your Clinic
Seek advice promptly if you notice:
Increasing pain, redness, or swelling after 3 days
Pus, yellow crusts, or unusual discharge
Fever or general unwell feeling
Dark or uneven pigmentation that worsens
8. Maintenance & Long-Term Care
Continue using gentle cleansers and bland moisturisers for several weeks.
Introduce active skincare (e.g., retinoids, acids) only when advised by your clinician. These should not be used through the course of your treatments.
Use SPF daily to preserve your results and protect collagen renewal.
By following these CO2 laser aftercare guidelines diligently, you can maximize the benefits of your treatment and enjoy healthier, rejuvenated skin. Always consult with your practitioner for personalised advice tailored to your skin type and treatment specifics.
