In most cases, the answer is yes, you can repeat CO2 laser treatments to maintain your positive results. However, the frequency will depend on the depth of your previous procedure and the level of correction you hope to achieve. If you had a fractionated treatment, this process stimulates collagen production by creating small channels deep in the skin, leaving surrounding skin and tissue untouched. This process will likely need to be repeated. Ablative laser treatments remove the outermost layers of skin to reveal softer, smoother skin below. This procedure requires a significant amount of recovery time afterward and the results can be quite dramatic. However, the procedure should not be repeated as a general rule, as this could cause excessive damage to the skin and tissue. I recommend scheduling a follow-up with your provider to determine whether your skin is ready for another treatment. Make sure you are working with a board-certified dermatologist to ensure your treatments are all safe and as successful as possible.
