What To Expect During CO2 Laser Resurfacing Treatment

Updated on October 15th, 2025

AD | CO2 laser resurfacing is a common skin treatment that can make the skin look smoother, healthier, and more even. This procedure works by removing the outer and middle layers of the skin to address concerns like wrinkles, fine lines, and uneven skin tone. Knowing what to expect before, during, and after the treatment can help you feel more prepared and confident about your decision.

What Is CO2 Laser Resurfacing?

CO2 laser resurfacing uses a focused beam of light to remove damaged skin layer by layer. The treatment also helps boost collagen production, which is important for firm, youthful skin. This procedure is a good option for people who want to improve the look of scars, sun damage, or age-related spots.

Your dermatologist will recommend this procedure based on your skin type and goals. People with lighter skin tones may see fewer side effects, but advancements in laser technology have made this CO2 laser treatment safer for many skin types.

Preparing for the Procedure

Getting ready for CO2 laser resurfacing treatment is an important step to ensure good results and lower the risk of complications.

1. Consultation and skin check: A dermatologist will assess your skin and discuss what you hope to achieve. You may be asked about your medical history and any past skin treatments.

2. Skin preparation: You may need to stop using certain products, like retinoids or exfoliating creams, a few weeks before your appointment. Some patients receive antiviral medicine to lower the chance of infection.

3. Sun protection and care: Stay out of direct sunlight for at least two weeks before the treatment. Wearing sunscreen and keeping your skin moisturized will also help your skin stay healthy.

Following these preparation steps helps create a solid foundation for the treatment and minimizes potential issues.

What Happens During the Treatment

Knowing the steps involved can make you feel more at ease.

1. Numbing the skin: A numbing cream is usually applied to the skin to reduce discomfort. For larger areas, local anesthesia or light sedation may be used.

2. Using the laser: The dermatologist uses a handheld CO2 laser to target the skin. The laser sends small pulses of energy that remove the top layers of skin and encourage new skin to grow. The session can take anywhere from 30 minutes to two hours, depending on how much skin is being treated.

3. After the procedure: Right after the treatment, your skin may feel warm and appear red and swollen, similar to a sunburn. A soothing cream or cooling device is often applied to help calm the skin.

These steps work together to ensure the procedure is effective and manageable.

Recovery and Aftercare

Taking care of your skin after the procedure is key to healing well and getting the best results.

1. Early healing: In the first few days, your skin will likely be tender and appear red or slightly crusted. Clean the treated area gently and follow any aftercare instructions provided by your dermatologist.

2. Keeping the skin moisturized: Use gentle, fragrance-free moisturizers to keep your skin hydrated and prevent dryness. Avoid using any harsh products or exfoliants until your skin fully heals.

3. Avoiding sunlight: Your skin will be very sensitive after the treatment, so apply broad-spectrum sunscreen daily. Wear a wide-brimmed hat and stay indoors during the hottest parts of the day whenever possible.

4. Peeling and renewal: After about a week, the treated skin will start to peel as new skin begins to grow. This is a normal part of the process, and it is important not to pick at peeling skin to avoid scarring.

Following these aftercare instructions helps promote a shorter recovery time and ensures your skin heals smoothly.

Possible Side Effects

CO2 laser resurfacing is generally safe, but it is helpful to know the potential side effects:

• Redness and swelling: These are common and can last for a few weeks while the skin continues to heal.

• Changes in skin color: Some people may experience temporary light or dark spots. Using sunscreen and following aftercare instructions can help prevent this.

• Scarring or infection: Although rare, these can happen if proper aftercare is not followed. Keeping the skin clean and moisturized can reduce this risk.

Understanding these side effects helps you stay informed and take the right precautions during the healing period.

The Results You Can Expect

One of the best parts of CO2 laser resurfacing is the noticeable improvement in your skin’s texture and tone. You may start seeing changes a few weeks after the procedure. The skin will continue to improve over the next few months as collagen production increases.

Some people may choose to have more than one treatment for even better results. Following a regular skincare routine that includes sunscreen, gentle cleansers, and moisturizers can help maintain the benefits of the procedure.

Is CO2 Laser Resurfacing Worth It?

Many people find that CO2 laser resurfacing boosts their confidence. Smoother, healthier-looking skin can make a big difference in how people feel about their appearance. Being informed and prepared helps you make the most of the treatment.

Final Thoughts

CO2 laser resurfacing can be a great option for improving the skin’s appearance. Preparing for the procedure and following aftercare instructions carefully can lead to better healing and lasting results. Although there may be some side effects, they are usually manageable with proper care. Consulting with a qualified dermatologist and setting realistic goals will help you feel confident about your decision and enjoy the benefits of the treatment.
