Light- and laser-based treatments won't cure active acne, so you may see additional breakouts after a laser procedure. Laser treatments may temporarily worsen acne, but they can ultimately be beneficial for many patients. Combining light and heat energy improves the appearance of both active acne and acne scars, which are treated deeper in the skin.
Acne is not cured by any laser treatment. Therefore, acne may continue after laser treatments. In fact, acne may temporarily worsen after laser resurfacing. Prescription medicines may be needed to control acne. It is best to have acne controlled with medications before pursuing laser treatment for scars.
