Laser technology is one of the most innovative scientific tools in medical use, today. The principles of the laser were originally presented by Albert Einstein in the early 1900's.
Since that time, scientists have developed several types of lasers which are used for a variety of purposes. One of the most recent is the fractionated carbon dioxide (CO2) laser that is used to treat sun-damaged skin, facial wrinkles, and scars in a procedure called laser skin resurfacing. This now offers much faster healing and less down time compared to previous lasers.
