CO2 Laser for Skin Health: Benefits and Risks

CO2 lasers have revolutionized dermatology, offering a variety of treatments for skin health and aesthetic improvement. This blog post delves into the benefits and risks of using CO2 lasers for skin health purposes, with a special focus on lesion removal.

What is a CO2 Laser?

A CO2 laser is a type of gas laser that uses carbon dioxide as its active medium. It produces a concentrated beam of infrared light that is highly absorbent by water and organic tissues, making it ideal for dermatological applications. The laser works by vaporizing the outer layers of skin, promoting new skin growth and improving overall skin texture and appearance.

Benefits of CO2 Lasers for Skin Health

1. Precision in Treatment
CO2 lasers offer unparalleled precision, allowing practitioners to target specific areas without affecting the surrounding tissues. This is particularly beneficial for delicate facial skin treatments, where accuracy is crucial for optimal results.

2. Effective Lesion Removal
One of the primary uses of CO2 lasers in Skinology is the removal of skin lesions, including warts, moles, and skin tags. The laser can precisely excise these lesions with minimal damage to the surrounding skin, often resulting in less scarring compared to traditional surgical methods.

3. Skin Resurfacing
CO2 lasers are highly effective for skin resurfacing, a procedure that helps reduce wrinkles, fine lines, and acne scars. By removing the outer layers of damaged skin, CO2 lasers stimulate collagen production, leading to smoother, more youthful-looking skin.

4. Minimally Invasive
CO2 laser treatments are minimally invasive, meaning they involve less trauma to the skin compared to traditional surgical procedures. This leads to shorter recovery times and reduces the risk of complications such as infections and excessive bleeding.

5. Customized Treatment
The settings of a CO2 laser can be adjusted to suit individual skin types and conditions, allowing for customized treatments tailored to each patient’s needs. This personalization enhances the effectiveness and safety of the procedures.

6. Long-Lasting Results
The effects of CO2 laser treatments can be long-lasting, especially when combined with a proper skincare routine and sun protection. Patients often enjoy smoother, clearer skin for years after the procedure.

Risks of CO2 Lasers for Skin Health

1. Thermal Damage
Although CO2 lasers are precise, there is a risk of thermal damage to surrounding tissues. Excessive heat from the laser can cause burns and scarring, particularly if the procedure is not performed correctly.

2. Pigmentation Changes
Some patients may experience changes in skin pigmentation following CO2 laser treatments. This can include hyperpigmentation (darkening of the skin) or hypopigmentation (lightening of the skin), especially in individuals with darker skin tones. This will most likely resolve over 6 months but it is a risk to be aware of before having this procedure. To minimise risks I will prep your skin with both product and treatment before doing a Co2 laser on you.

3. Infection
While CO2 laser treatments are minimally invasive, there is still a risk of infection, particularly if the treated area is not properly cared for after the procedure. Following post-treatment care instructions is crucial to minimize this risk.

4. Prolonged Redness and Swelling
Patients may experience redness and swelling in the treated area, which can last for several days to weeks. In some cases, this can be prolonged, causing discomfort and affecting the patient’s appearance during the recovery period.

5. Cost
The cost of CO2 laser treatments can be high, which may be a barrier for some individuals. While the benefits often justify the expense, it remains a significant consideration, especially for those without insurance coverage for cosmetic procedures.

6. Need for Multiple Sessions
Depending on the condition being treated, multiple CO2 laser sessions may be required to achieve the desired results. This can increase the overall cost and time commitment for patients.


CO2 lasers offer numerous benefits for skin health, particularly in the removal of lesions and skin resurfacing. Their precision, effectiveness, and minimally invasive nature make them a popular choice in dermatology. However, it is essential to be aware of the potential risks, including thermal damage, pigmentation changes, and infection. Consulting with a qualified dermatologist and following all pre- and post-treatment care instructions can help maximize the benefits and minimize the risks of CO2 laser treatments.

As with any medical procedure, informed decision-making and professional guidance are key to achieving the best possible outcomes. If you are considering CO2 laser treatment for skin health purposes, make sure to discuss all options, risks, and benefits with your dermatologist to determine the most appropriate course of action for your specific needs.

Caroline has been amazing! I started going to Caroline about a year before my wedding as I suffer from bad pigmentation. Caroline went through the best options for me and give me a personalised skin care routine that was reviewed and tweaked monthly with visits and recommended products and the results were amazing! She was always on hand to answer anything I needed and I could never have believed before I started on my skin journey that we would have received the results we did.

Every experience I have had with Caroline has been a positive one. Caroline is a fountain or knowledge, Any problem I have had with my skin she has been able to solve. Her warm personality and her professional manner makes the whole experience even better. I would 100% recommend her.

Fantastic! Caroline is both professional and delightful! What I loved about my last visit is being reassured she will not decided on exactly what treatment to give until she sees your skin. The service is tailored to exactly what your skin needs and her service is adapted to function to what's best for you! I can highly recommend Caroline and have happily handed over my face to her skilled hands!

I continue to see Caroline to help manage my skin and I couldn’t be happier. I can’t thank Caroline enough for getting my skin wedding ready and helping my confidence by treating my pigmentation- it really made a huge difference and I am so glad she was recommended to me and I would highly recommend her to anyone worried about their skin!

As a chronic acne sufferer with 2 failed courses of roaccutane & having tried many different skin care regimes and products in the past 15 or so years I felt like I had exhausted all options for calming my skin. My acne was active, painful and unsightly when I attended my first appointment. Caroline assured me we could improve my skin condition and looked at all aspects of my lifestyle and skin care regime and advised me on small changes to get the best results. What I loved best about the initial series of appointments was that each one was specifically tailored to how my skin was behaving at that time. We have now moved on to Skin Pen sessions to tackle the scarring as I have no active breakout left to treat.

Fantastic, professional and personable service. As an overseas client I have been amazed at Caroline's skin analysis, expertise and product recommendations for my skin which has never been so well looked after. Delivery is always super quick and she is always available for questions and guidance on any concerns. Caroline is an expert at what she does, so much so she can work her magic from across the Irish sea!

It has been the best investment I have ever made in my skin. Caroline has gotten my skin from something I was cautious of every day to me now feeling completely confident in my skin to even getting compliments on my skin. I wouldn't go anywhere else! Amazing service.

Gillian Welsh

I couldn’t recommend Caroline and her expertise enough. She’s knowledgable, professional and fantastic at her job.

Elizabeth Evans

Caroline couldn't have been more welcoming, made the consultation very relaxing while remaining professional. Clearly very knowledgeable from her experience and studies we talked about my skin care goals and I underwent the CosMedic Benefit skin peel treatment with the Celluma LED Light Therapy. This was beyond relaxing and I have had a great result from it: Reduction in deep and fine lines on my forehead and around my eyes. I will certainly be coming back and recommending you to everyone. Thank you!
