What is a laser? A laser is a high-energy beam of light that can selectively transfer its energy into tissue to treat the skin. Lasers contain a material that produces and amplifies light. Two mirrors cause the light to reflect back and forth through this material. The result is a light beam that is collimated and intense. This light is either one pure color or several different pure colors. These properties which separate the laser from a light bulb, are important to the medical application of lasers.
Many procedures cannot be done without the laser. Likewise, many procedures are better performed without the laser. Even with the sparkle, pure color, and high-energy beam, the laser is not always the best tool for surgery. The choice of using a laser or other surgical methods is carefully made by the facial surgeon.
