Carbon Dioxide (CO2) Laser Resurfacing

Procedure and Results

Typically, the carbon dioxide laser resurfacing procedure takes 30-90 minutes. Local anesthetic is used for small treatment areas, while general anesthesia may be administered when treating larger target areas. The healing process takes anywhere from 2-4 weeks, depending on the extent of treatment. Patients must follow careful aftercare instructions to prevent scarring or extended healing times. 

Desired results gradually develop over several months while the skin heals and rejuvenates. Many patients will experience redness and hyperpigmentation for the first 2-3 months; in some cases, it may take up to 6 months for the redness to completely fade. Once the skin has fully healed, the procedure results can last several years. However, the longevity of the results will depend on individual factors such as lifestyle, skincare routine, age, and skin type. 

Clinical Applications

The applications for carbon dioxide laser resurfacing are most often cosmetic, such as the reduction of wrinkles and fine lines, reversing the effects of sun damage, treating various types of scars and warts, and removing benign skin growths, including linear epidermal nevi and rhinophyma. This technology has also proven effective in removing skin layers affected by benign and malignant skin conditions. 

Risks 

Carbon dioxide laser resurfacing, while effective, encompasses risks such as the development of milia, acne flares, and potential hyperpigmentation or hypopigmentation. Pre- and post-operative medications are administered to mitigate the chance of herpes simplex reactivation and bacterial infections. Although uncommon, scarring is a potential risk, and healing can be delayed in smokers. Post-operative swelling is anticipated but can be controlled with the judicious use of steroids and adherence to advised aftercare, including diligent sun protection, to foster optimal outcomes.
