Essential After-Care for CO₂ Laser Resurfacing in London, Ontario: Your Step-by-Step Guide

CO₂ Laser Aftercare: Why It Matters

Choosing CO₂ laser resurfacing is an exciting step toward smoother, healthier-looking skin. Whether your goal was to soften fine lines, refine texture, or improve sun damage, the real transformation happens after your appointment — during the healing phase.

At Infinite Medical Spa London, we always remind clients that post-treatment care is half the treatment’s success. How you treat your skin in the days and weeks following can make the difference between a comfortable recovery and prolonged irritation.

What to Expect After CO₂ Laser Resurfacing

It’s completely normal for your skin to feel warm, tight, and slightly swollen after your procedure — similar to a strong sunburn. You may notice:

• Redness and mild swelling for several days

• A feeling of heat or sensitivity

• Oozing or crusting as the outer layer renews itself

• Peeling or flaking around days 3–7

• Pink or rosy skin for several weeks as new collagen develops

These reactions show that your skin is healing and regenerating. The process takes time, and patience is key. Most people find their skin looks refreshed and more even once the redness fades — typically within a few weeks, with continued improvement over several months.

Step-by-Step Aftercare Guide

Day 0: Treatment Day

• Your provider will apply a protective ointment before you leave. Keep this on as directed.

• Use cool compresses to ease warmth or swelling.

• Avoid touching or rubbing the skin.

• Sleep with your head slightly elevated to minimize swelling, especially if the treatment included the eyes or cheeks.

Days 1–3: Protect and Soothe

• Cleanse gently using cool or lukewarm water and a soft cloth — no scrubbing.

• Apply a healing ointment or barrier cream frequently to prevent dryness and support skin regeneration.

• Avoid makeup, direct sunlight, hot showers, saunas, or any activity that causes sweating.

• Continue using cold compresses as needed.

Days 4–7: The Peeling Phase

• As peeling begins, resist the urge to pick or pull at the skin. Let the exfoliation happen naturally.

• Continue moisturizing regularly — skin that stays hydrated heals more smoothly.

• You may switch to a lighter, fragrance-free moisturizer once the raw phase subsides (your provider will guide you).

• Continue strict sun protection whenever you’re outdoors.

Week 2 and Beyond: Repair and Protect

• Mild redness may persist. This is a normal sign of new, healthy skin forming.

• Begin reintroducing your usual skincare products gradually — avoid exfoliants, acids, or retinol until your provider confirms it’s safe.

• Use a broad-spectrum, mineral-based SPF 30 or higher every day, even on cloudy days.

• Avoid direct sun exposure, tanning, and hot environments for several weeks.

Why Aftercare Is So Important

CO₂ laser resurfacing works by creating controlled micro-injuries in the skin to stimulate regeneration. That means your skin is temporarily more vulnerable to bacteria, UV exposure, and dehydration.

Proper aftercare:

• Reduces infection risk

• Minimizes redness and post-inflammatory hyperpigmentation

• Encourages even collagen production

• Protects your investment in the treatment

Think of it as partnering with your skin to help it do what it does best — heal beautifully.

London, Ontario-Specific Tips

Our climate can influence your recovery:

• Fall and winter: Indoor heating can dry your skin. Use a humidifier and apply moisturizer more frequently.

• Spring and summer: Be extra cautious with UV exposure — even on cloudy days, sunlight can affect healing skin.

• General tip: Plan some quiet downtime for 5–7 days after your treatment. You’ll want to minimize makeup, social events, and sun exposure during early healing.

When to Contact Your Provider

Reach out to your medical spa or practitioner if you notice any of the following:

• Increasing redness or swelling beyond expected levels

• New or worsening pain, discharge, or an unusual odour

• Blisters or thick crusts forming after initial healing

• Dark spots or uneven pigmentation developing suddenly

Prompt communication ensures you stay on track for a smooth recovery.

Frequently Asked Questions

1. When can I wear makeup after CO₂ laser resurfacing?
Typically, you can wear makeup once the skin has fully re-epithelialized — usually around 7–10 days post-treatment. Always use clean, mineral-based products and remove them gently at night.

2. How long should I avoid the sun after my CO₂ laser treatment?
It’s essential to avoid direct sunlight for at least 4–6 weeks. Once you resume outdoor activity, apply a mineral sunscreen daily and reapply every 2–3 hours if exposed to sunlight.

3. Can I exercise after CO₂ laser resurfacing?
Avoid exercise, hot yoga, and saunas for the first 5–7 days. Sweat and heat can irritate freshly treated skin and delay healing.

4. How long will redness last?
Mild redness can persist for several weeks as your skin remodels. Using gentle skincare, keeping skin moisturized, and protecting from UV light will help it fade faster.

5. When will I see my final results?
While early improvements are visible within weeks, collagen continues to remodel for 3–6 months after treatment. The final result is smoother, more even-toned skin with improved texture and luminosity.
