Do not focus on the specific laser used for your treatment as much as the experience and expertise of the physician performing the procedure. For example, I have developed a proprietary treatment I call the Take10, which uses a combination of lasers to turn back the clock on your appearance by up to 10 years or more. I do use a CO2 laser for many of these procedures, but I might add a vascular or pico second laser to ensure I address all the aging symptoms in the treatment area. I encourage you to find a very experienced, board-certified dermatologist with expertise in a wide range of laser and energy devices. Through an in-person assessment and discussion of your needs and goals, your doctor will create a customized treatment plan that will produce the best results for you.
