Fractionated CO2 laser resurfacing for acne scars, wrinkles, and sun damage in Juno Beach, FL
Fractionated CO2 laser resurfacing uses a carbon dioxide laser to make thousands of tiny channels in your skin. Healthy skin is left between each channel, so you heal faster than with older full-surface lasers. Your body then rebuilds collagen in the treated areas. Skin usually looks healed within 7 to 10 days, and results continue to improve for about 6 months. Most people need one to three sessions.

How Fractionated CO2 Laser Resurfacing Works
A CO2 laser gives off infrared light at 10,600 nanometers. Water strongly absorbs this light, and your skin is mostly water, so the energy stays exactly where it is aimed.
Older CO2 lasers removed the entire skin surface at once. That worked, but it left a large open wound and carried real risk. Fractional treatment, introduced in 2004, instead splits the beam into thousands of microscopic columns. The untouched skin in between acts as a healing reservoir, so recovery is much faster.
Underneath, two things happen in order. First, your body clears out old, sun-damaged collagen. Then it builds new collagen to replace it. In one study of photodamaged skin, new collagen production peaked at about 21 days after treatment and stayed elevated for at least six months. That is why your skin keeps looking better for months rather than changing all at once.
What Fractionated CO2 Laser Resurfacing Treats
- Acne scars. The strongest evidence. In a study of 103 patients, scar severity scores dropped about 43 percent after an average of two sessions. Wide, shallow boxcar scars respond better than narrow icepick scars.
- Fine lines and wrinkles. Good improvement, especially around the mouth and eyes.
- Sun damage and uneven tone. Pigment tends to respond the best of any concern.
- Rough or crepey texture and enlarged pores.
- Surgical scars. Timing matters. Research suggests treating within about a month of surgery works significantly better than waiting several months.
If acne scarring is your main concern, our acne and acne scar page covers all the options. You can see real results in the CO2 before-and-after gallery.

What Recovery from Fractionated CO2 Laser Resurfacing Looks Like
| When | What to expect |
|---|---|
| Days 1 to 3 | Redness, swelling, and warmth. Swelling usually peaks around day 2 or 3. |
| Days 3 to 7 | Skin turns bronze and feels like sandpaper, then peels. Swelling goes down. |
| Days 7 to 10 | New skin, still pink. Most people return to normal activities and can wear makeup. |
| Weeks 2 to 6 | Pink tone fades. Collagen rebuilding is at its most active, even though you cannot see it yet. |
| Months 2 to 6 | Steady improvement in texture, tone, scars, and fine lines. |
Sun protection is part of the treatment, not optional aftercare. Sun exposure while you heal is the most common cause of dark spots afterward, and it interferes with collagen rebuilding. That matters more here in Palm Beach County than almost anywhere. Do not schedule this right before a beach week in Jupiter.
Fractionated CO2 Laser Resurfacing Risks
This procedure removes tissue, so it carries real risk.
- Expected: redness, swelling, bronzing, peeling, and itching. Redness after deeper treatments can last several weeks.
- Uncommon: dark spots after healing, redness lasting longer than expected, small bumps or breakouts.
- Rare but serious: infection, permanent light patches, or scarring.
Skin tone is the biggest factor in the risk of dark spots. Older full-surface CO2 lasers caused hyperpigmentation in more than 37 percent of patients with darker skin. Fractional treatment lowers that risk substantially, but does not remove it. If you have a deeper skin tone, the settings must be adjusted for you, which is exactly why an in-person exam comes first.
You may not be a candidate if you have an active skin infection, recent isotretinoin use, a history of keloid scarring, or cannot avoid the sun while healing.
Who performs your treatment?
Ask this before you book anywhere. In a 2024 study comparing laser practices, the physician personally performed the laser treatment 60 percent of the time at dermatology practices, 33 percent at plastic surgery practices, and only 9 percent at medical spas.
At Perfect Skin MD, Dr. Susan Schroeder personally performs every CO2 treatment, from choosing your settings through every pass. She has used CO2 lasers since 2000. You can check any Florida doctor’s license through the Florida Department of Health and board certification through the American Board of Dermatology.
We use the Lumenis AcuPulse system with DeepFX and ActiveFX. DeepFX goes deeper for wrinkles and acne scars. ActiveFX works closer to the surface for tone and fine lines. Both are FDA-cleared for skin resurfacing. Full procedure details are on our CO2 laser service page.
Common Questions about Fractionated CO2 Laser Resurfacing
How many sessions will I need?
Usually one to three. Sun damage and texture often improve with a single deeper session. Acne scars typically need more; in one study of 103 patients, the average was two sessions to reduce scar severity by about 43 percent. Sessions are spaced several weeks to several months apart.
How much downtime is there?
Your skin usually heals in about 7 to 10 days, and most people return to normal activities and makeup at that point. Some pink tone can linger for a few weeks. Deeper treatments mean longer recovery, so ask specifically about your plan.
When will I see my final result?
Not right away. Collagen production peaks around 21 days and stays elevated for at least six months, so your skin keeps improving well after it looks healed. We usually judge results at three to six months. Scar cases can keep refining for a year or more.
Is it safe for darker skin tones?
It can be, with adjusted settings, but the risk of dark spots is significantly higher and must be managed. Older full-surface CO2 lasers caused hyperpigmentation in more than 37 percent of patients with darker skin, while fractional treatment lowers that risk considerably. Your skin type changes the depth, density, and preparation we use.
Does it hurt?
Numbing cream is applied before treatment, and most patients describe the sensation as a hot, prickling sensation rather than sharp pain. A full-face session usually takes 20 to 60 minutes, depending on what is being treated.
How is this different from microneedling?
A CO2 laser produces stronger results for acne scars but requires more downtime and carries a higher risk of dark spots. Radiofrequency microneedling is gentler with faster recovery but less dramatic improvement. Which one fits you depends on your scars, your skin tone, and how much recovery time you can take.
