Hi Cassieaa, Lifting a scar with with a dense filler like Voluma is an important component of CO2 scar treatments. It is safe and effective to perform CO2 ablative laser immediately following the injection of Voluma to lift scars. If you and your physician prefer to have some time between the treatments that will be equally as effective. In my experience, repeating treatments at 6 months should be considered. Combining other treatments, such as a skin care program (like ZO), meso therapy, and PRP will be of additional benefit. For best results, find an experienced physician and start with a comprehensive treatment plan to prepare your skin and build out a strategy that fits your budget and schedule from there. Good luck from Vancouver, Canada!
