Scarring in the area you describe can be difficult to treat. It is true that the face heals in a more predictable manner than other areas of the body. This is in part due to the hair follicles that are present-- these are a reservoir of skin cells that repopulate the area that is ablated by the laser. This may be the same reason why some people tend to get hypertrophic scars on the ears, chest, back, and arms.
There are no guaranteed results for any cosmetic treatment, but lasers can help. There has been much interest in deep fractional lasers for scarring, such as the DeepFX laser. This application is still being studied, but DeepFX may be more appropriate than ActiveFX. Many burn victims have benefitted from deep fractional ablation in this way. The Fraxel Repair is another similar laser that works in the same way to reduce scars.
