This refers to the process of creating individual vertical channels of injury into the skin, leaving the majority of the skin intact. Through this process, the thermal channels created by the laser break down scar tissue and damaged skin, stimulating a natural healing response. Collagen production is stimulated, thereby closing in the open channels and creating a stronger, healthier foundation for the skin. This type of technology is used to treat all types of scarring. Still, it is also used as a preventative treatment to stimulate collagen growth to replace the collagen that we lose through the natural aging process.
