How Long to Wait for the 2nd Treatment for (Matrix) Co2 Fractional Laser Treating Acne Scars?

Fractional CO2 laser treatments, such as the Sandstone Matrix CO2 laser, can be a great treatment for acne scarring. Multiple treatments are often necessary. I like to wait at least 3 months between treatments, but it is fine to wait more, even 6-12 months, as there are changes that continue in the deep dermis such as collagen remodeling. Hope this helps.
