The Carbon Peel Laser has been shown to improve the outcome of cystic acne. It helps to remove the dead skin of the surface, and reduces oil secretion and pigmentation. However as with all heat-based therapies, from experience, including IPL/Co2 Laser, there is a small limited outbreak following the treatment in the initial days.
Fortunately, the outbreak tends to be self-limiting and recovers rather quickly. So take heart!
