When it comes to skin resurfacing, two treatments stand out: Fraxel and the CO₂ laser. Both can smooth wrinkles, fade sun damage, and improve texture — but they sit at opposite ends of the intensity spectrum.
If you’re wondering whether to go for the gentler, buildable Fraxel or the powerhouse CO₂ laser, here’s how they compare 👇
🔬 What They Are
🌟 Fraxel (Non-Ablative Fractional Laser)
- Uses 1550nm and/or 1927nm wavelengths
- Creates microscopic thermal injuries without removing the top layer of skin
- Fractional = treats small columns of skin while leaving surrounding tissue intact
- Requires a series of sessions for results
🔥 CO₂ Laser (Traditional Ablative)
- Fully ablative = removes the entire epidermis in treated zones
- Heats the dermis deeply to remodel collagen
- Considered the gold standard for dramatic resurfacing
- Usually requires only 1 session
💡 What Each Treats Best
Fraxel
✔ Fine lines & early wrinkles
✔ Pigmentation (sun spots, melasma, brown patches)
✔ Mild acne scars
✔ Uneven tone
✔ Preventative anti-aging
CO₂ Laser
✔ Deep wrinkles (smoker’s lines, crow’s feet, forehead creases)
✔ Severe sun damage
✔ Thickened or leathery skin
✔ Acne scars (moderate–severe)
✔ Advanced texture changes
📊 Side-by-Side Comparison
| Feature | Fraxel | CO₂ Laser |
|---|---|---|
| Type | Fractional, non-ablative | Fully ablative |
| Depth | Thermal micro-columns (no removal) | Removes top layer + heats dermis |
| Best For | Pigmentation, fine lines, mild scars | Deep wrinkles, severe sun damage, advanced aging |
| Sessions | 3–5 | 1 (sometimes 2) |
| Downtime | 2–5 days (redness, bronzing, flaking) | 7–14 days (oozing, crusting, peeling) |
| Results Timeline | Gradual improvement over weeks–months | Dramatic results in weeks; full healing may take months |
| Strength | 🔥🔥 (gentle–moderate) | 🔥🔥🔥🔥🔥 (aggressive) |
| Risk Level | Low (safe for most skin types) | Higher (PIH, infection, longer redness) |
✅ Who Should Choose Which?
- Choose Fraxel if:
- Your main concern is pigmentation, sun spots, or melasma
- You want gentler resurfacing with less downtime
- You’re younger or earlier in your anti-aging journey
- You don’t mind doing multiple sessions
- Choose CO₂ if:
- You have deep wrinkles, advanced sun damage, or severe scarring
- You want dramatic, one-and-done results
- You’re prepared for 1–2 weeks of recovery
- You’re okay with higher risks for maximum change
🧴 Post-Treatment Care
Whether you go for Fraxel or CO₂, aftercare is crucial:
Do:
- Use gentle cleansers & rich moisturizers
- Apply SPF 30–50 mineral sunscreen daily
- Stay hydrated & avoid direct sun
Don’t:
- Pick at flaking or peeling skin
- Use retinoids, acids, or scrubs until cleared by provider
- Expose your skin to excess heat or sweating
💬 Final Thoughts
✨ Fraxel = gradual improvement, pigment correction, and collagen boost with manageable downtime.
🔥 CO₂ = aggressive resurfacing, deep wrinkle reduction, and dramatic results — but with longer recovery.
Think of it like this:
- Fraxel = “build-your-results” plan (multiple sessions, lower risk, pigment-focused)
- CO₂ = “reset button” (one treatment, major change, big downtime)
Both can transform your skin — the right choice depends on whether you want a gentle series or a bold reset.
