Fraxel Laser is one of the many types of Fractionated Lasers available on the market today. Although the Fraxel was the first Fractional Laser created, they all work on the same principal.

This heat tunnel is deep enough to cause the stimulation of new collagen fibers which results in an improvement of the acne scar.
