CO2 Laser Resurfacing Aftercare: What To Do And What To Avoid

CO2 laser resurfacing can dramatically improve fine lines, wrinkles, scars, and sun damage—but your results depend heavily on how you care for your skin afterward. This guide walks you through what to do and what to avoid so you can heal safely and get the best possible outcome. For details on the procedure itself, you can also explore the dedicated CO2 resurfacing treatment page.

Understanding Your Skin After CO2 Laser Resurfacing

CO2 laser resurfacing works by creating controlled damage to the outer and deeper layers of the skin. This triggers your body’s natural healing response, stimulating new collagen and revealing smoother, more even skin over time. In the first days and weeks after treatment, your skin is essentially in “repair mode,” which means it is:

• Extremely sensitive, dry, and vulnerable to infection and irritation

• More reactive to sun exposure, heat, and harsh products than usual

• Actively rebuilding collagen and new skin cells beneath the surface

Because of this, aftercare is not just about comfort—it is about protecting the delicate new skin, reducing the risk of complications, and preserving your long-term results. Think of the procedure as only half the journey; the rest is how you treat your skin at home.

What To Do: Essential CO2 Laser Aftercare Steps

1. Follow Your Provider’s Instructions Exactly

Your dermatologist or aesthetic provider will give you a personalized aftercare plan based on the depth and intensity of your treatment. This may include prescription creams, specific cleansing routines, and pain relief options. Always prioritize their instructions over generic advice, as they know your skin type, medical history, and the exact settings used during your procedure.

💡 Pro Tip: Take a photo of your written aftercare instructions and set phone reminders for medication and skincare steps during the first week.

2. Keep The Skin Clean And Gently Hydrated

In the first days after CO2 laser resurfacing, your skin may ooze, crust, or feel tight and hot. Proper cleansing and moisture are key to preventing infection and supporting healing:

• Use the recommended gentle cleanser or saline solution to wash your face, usually 2–4 times per day, depending on your provider’s plan.

• Pat the skin dry with a clean, soft towel or gauze—never rub or scrub.

• Apply a healing ointment or occlusive moisturizer (such as petroleum jelly or a prescription barrier cream) as directed to keep the skin from drying out and cracking.

Moisture helps the top layer of treated skin shed more comfortably and reduces the risk of scabbing and scarring. Keeping everything clean and lightly coated also provides a protective barrier against bacteria.

3. Protect Your Skin From The Sun—Every Single Day

Sun protection is one of the most important parts of CO2 laser aftercare. Freshly resurfaced skin is highly prone to hyperpigmentation (dark patches) and damage if exposed to UV rays. To protect your results:

• Stay indoors as much as possible for the first 1–2 weeks, especially during peak sun hours.

• Once your provider says sunscreen is safe to apply, use a broad-spectrum SPF 30 or higher, ideally a mineral formula with zinc oxide or titanium dioxide.

• Wear a wide-brimmed hat, sunglasses, and seek shade any time you are outdoors for several weeks to months after treatment.

Think of sun protection as a long-term habit, not just a short-term step. Collagen and pigment changes continue for months, so consistent SPF use helps maintain your smoother, more even complexion.

Consistent sun protection after CO2 laser dramatically reduces dark spots and preserves results.

4. Manage Discomfort Safely

Redness, swelling, warmth, and a sunburn-like sensation are all normal after CO2 laser resurfacing. To stay comfortable:

• Use cold compresses or wrapped ice packs for short intervals, if recommended, to reduce heat and swelling.

• Take approved pain relievers (often acetaminophen) as instructed by your provider.

• Sleep with your head slightly elevated the first few nights to help minimize swelling.

Mild itching is also common as the skin heals. Keeping the area moisturized and cool usually helps, but let your provider know if itching becomes intense or is accompanied by a rash or severe discomfort.

5. Be Patient And Gentle With Your Routine

Healing from CO2 laser resurfacing is a process, not an overnight transformation. You may experience redness for weeks and subtle pinkness for months. During this time:

• Introduce your regular skincare products slowly and only with approval from your provider.

• Use simple, fragrance-free moisturizers and cleansers designed for sensitive skin during the early weeks.

• Attend all scheduled follow-up appointments so your provider can monitor healing and adjust your routine.

Remember: visible improvements continue to develop for three to six months as collagen rebuilds. Gentle, consistent care pays off over time.

What To Avoid: Habits That Can Harm Healing Skin

1. Do Not Pick, Scratch, Or Peel Flaking Skin

As your skin heals, it will naturally form thin crusts or flakes and then shed. It can be tempting to “help” the process along, but picking can cause scarring, infection, and uneven pigmentation. Instead:

• Keep nails short and avoid touching your face unnecessarily.

• Apply your healing ointment as directed to soften crusts and let them fall off on their own.

📌 Key Takeaway: If you would not peel off a scab from a fresh cut, do not peel off flaking skin after CO2 laser resurfacing either.

2. Avoid Harsh Or Active Skincare Ingredients Too Soon

Many beloved skincare products are far too strong for freshly treated skin. Until your provider gives the green light, do not use:

• Retinoids (retinol, tretinoin, adapalene, and similar vitamin A products)

• Exfoliating acids (AHAs, BHAs, glycolic, lactic, salicylic acid)

• Scrubs, cleansing brushes, or any physical exfoliants

• Strong vitamin C serums, benzoyl peroxide, or alcohol-based toners

These ingredients can cause stinging, redness, delayed healing, and even long-term sensitivity if reintroduced too early. When in doubt, keep your routine minimal and ask before adding anything new.

3. Skip Makeup Until You Are Cleared To Use It

Many people want to cover redness and flaking with foundation or concealer, but applying makeup too soon can trap bacteria, clog pores, and irritate healing skin. Typically, providers recommend:

• Avoiding all makeup on treated areas for at least 7–10 days, sometimes longer for deeper treatments.

• Starting with mineral-based, fragrance-free formulas once the skin surface has fully re-epithelialized (formed a new intact layer).

When you do resume makeup, wash your brushes and sponges thoroughly or replace them to avoid introducing bacteria to delicate skin.

4. Avoid Heat, Sweat, And Intense Exercise Early On

Heat and sweating can worsen inflammation and increase the risk of irritation or infection. For at least the first week—or as advised by your provider—avoid:

• Hot yoga, intense workouts, and heavy cardio that make you flush and sweat heavily

• Saunas, steam rooms, hot tubs, and very hot showers or baths

Gentle walking is usually fine and can support circulation, but keep your environment cool and avoid direct sun while you heal.

5. Do Not Smoke Or Vape During Recovery

Smoking and vaping reduce blood flow to the skin and can significantly slow healing. They also increase the risk of complications and may blunt the collagen-boosting benefits of your treatment. If possible, use your CO2 laser recovery as an opportunity to quit or at least pause nicotine use for several weeks before and after your procedure.

6. Do Not Ignore Warning Signs

Some redness, swelling, and discomfort are expected, but certain symptoms may signal a problem that needs medical attention. Contact your provider promptly if you notice:

• Increasing pain, warmth, or swelling after the first few days instead of gradual improvement

• Pus, foul odor, or yellow-green discharge from treated areas

• Fever, chills, or feeling generally unwell

Early treatment of infection or other complications can prevent more serious issues and help protect your final results.

Setting Realistic Expectations For Healing And Results

Everyone heals at a slightly different pace, depending on the depth of treatment, overall health, age, and skin type. As a general guideline, many people experience:

• 1–2 weeks of visible redness, crusting, and peeling where social downtime may be needed

• Several weeks of lingering pinkness that can usually be softened with gentle makeup once cleared

• Gradual improvement in texture, fine lines, and pigmentation over 3–6 months

Keeping your expectations realistic and planning your schedule around the initial healing phase can make the process feel less stressful. Some people choose to schedule their procedure before a long weekend, vacation at home, or quieter work period.

The Bottom Line: Partner With Your Skin For The Best Outcome

CO2 laser resurfacing is a powerful treatment that can deliver impressive, long-lasting improvements—but it is a partnership between the technology, your provider, and you. By knowing exactly what to do—keep the skin clean, hydrated, protected from the sun, and follow instructions—and what to avoid—picking, harsh products, early makeup, heat, smoking, and ignoring warning signs—you give your skin the best chance to heal beautifully.

If you are considering CO2 laser resurfacing or are already scheduled, use this guide as a conversation starter with your provider. Ask them to tailor these general do’s and don’ts to your specific treatment plan. With thoughtful aftercare and a bit of patience, you can help ensure that the short-term downtime is well worth the long-term glow.
