How to Take Care of Your Skin After CO2 Laser Resurfacing
CO2 laser resurfacing is a powerful non-invasive procedure used to improve skin texture, reduce fine lines, and treat scars. While the results can be impressive, how you care for your skin afterward plays a big role in how well you heal and how long your results last.
If you’ve just come home from a CO2 laser treatment or are planning to get one, this guide will walk you through what to expect and how to support your skin’s recovery.
What Happens Right After CO2 Laser Resurfacing?
Immediately after the procedure, you can expect redness, swelling, and sometimes pinpoint bleeding. Many people describe the sensation as similar to a sunburn. If you had a fractional CO2 laser, you might see small white or dark dots where the laser touched the skin.
Your provider will usually apply a thin layer of protective cream or ointment before you leave the clinic. Over-the-counter painkillers can help ease discomfort once the local anesthesia wears off. During the first few hours, it’s common to feel heat in the treated area. Using cold compresses for about 10 minutes each hour can help reduce this.
First Few Days: Clean and Protect
During the first two to three days, the swelling may peak, especially around the eyes. Your skin will likely ooze clear or yellowish fluid, which will dry into small crusts. It’s very important not to scratch or pick at these crusts, as doing so can increase the risk of scarring.
Here’s a simple care routine to follow during these early days:
- Gently clean the skin with a mild cleanser or diluted vinegar solution as recommended by your doctor. Avoid scrubbing or rubbing.
- Apply a bland moisturizer like Aquaphor or Cetaphil, or use a thin layer of Vaseline or another petrolatum-based ointment to keep the area moist.
- Use ice packs on and off throughout the day to ease swelling.
- Keep your head elevated when you sleep to reduce puffiness.
Even though you can move around and do light activities, avoid anything that causes heavy sweating, as this can irritate your healing skin.
Days Three to Seven: Peeling and Flaking
By the third or fourth day, swelling usually subsides, but redness remains. You’ll notice your skin starting to flake and peel, sometimes developing a rough or sandpaper-like texture. This is normal.
Most patients start to see the dead skin slough off around days five to seven. On the face, the healing process typically wraps up within a week, though off-face areas like the hands or arms may take up to two weeks.
This is the phase when it’s tempting to speed things up by exfoliating, but it’s crucial to let the skin peel naturally. Continue your gentle cleaning and moisturizing routine, and steer clear of scrubs, glycolic acid, Retin-A, or any harsh products.
If you had a CO2 laser resurfacing treatment done as part of a fractional CO2 laser plan, remember that the skin may stay pink or sensitive for longer, depending on the depth of treatment and your individual skin response.
Week Two and Beyond: Redness and Sun Care
Even after the peeling phase ends, your skin may look pink or red, similar to a mild sunburn. This can last several weeks or even months, depending on your skin type and how aggressively you were treated. Blondes and redheads, in particular, may notice prolonged redness.
During this time, you can apply makeup to cover the pink tones if you like. Choose non-comedogenic (non-clogging) products to avoid breakouts.
Most importantly, sun protection becomes a top priority. You’ll need to:
- Apply a broad-spectrum sunscreen (SPF 30 or higher) every day, even if you’re indoors.
- Reapply sunscreen every two hours if you’re outside.
- Wear a wide-brimmed hat and protective clothing when you’re outdoors.
Neglecting sun protection can increase the risk of hyperpigmentation (dark patches) or hypopigmentation (light spots) after your laser resurfacing.
Common Side Effects and When to Call Your Doctor
While fractional CO2 laser treatments are generally safe, some side effects can show up during healing. Here’s what you might notice:
- Mild acne flares due to heavy ointments or clogged pores.
- Cold sore reactivation if you have a history of herpes infections.
- Small white bumps (milia) that may appear temporarily.
- Persistent redness that takes longer to fade in some people.
You should contact your clinic if you notice:
- Severe or worsening pain.
- Increased redness and swelling instead of gradual improvement.
- Signs of infection (bleeding, pus, fever, or new cold sores).
- Blisters or raw, open skin.
Your CO2 laser resurfacing clinic can advise you on whether you need an in-person check or adjustments to your aftercare plan.
Tips to Support Healing
To make your recovery as smooth as possible, keep these practical tips in mind:
- Use extra pillows at night to keep your head elevated.
- Avoid smoking, alcohol, and heavy exercise during the first week, as these can slow healing.
- Stick to gentle skin care products (look for brands like Dove, Cetaphil, Neutrogena, or Aveeno).
- Once you’re fully healed, you can gradually reintroduce your usual products, including any bleaching creams or active treatments.
Remember, CO2 laser resurfacing is not a quick fix, but a process. It takes time for your skin to rebuild collagen, smooth out fine lines, and soften scars. Be patient and follow your clinic’s guidance.
Final Thoughts
Fractional CO2 laser treatments are one of the most effective non-invasive procedures for renewing your skin. Whether you’re targeting scars, wrinkles, or uneven texture, proper aftercare is the foundation for great results.
Listen to your provider’s instructions, treat your skin gently, and don’t rush the healing process. With care and consistency, you’ll give your skin the best chance to recover beautifully and enjoy long-lasting improvements.
