The word laser is an acronym for “light amplification by stimulated emission of radiation”.
Simply explained, laser is light that is focused to very small diameters, becoming so concentrated that the light energy can be made to cut and drill.
Lasers Are Everywhere!
Lasers play an important role in our everyday lives, and are used in an amazing range of products and technologies.
Police use laser when they measure speed. It is used in CD players, laser printers, laser pointers and much more.
Another application of laser is the removal of undesirable body hair.
This process passes a laser beam through the skin to an individual hair follicle. The intense heat of the laser damages the follicle, which inhibits future growth.
Laser is most effective for people who have light skin and darker hair.
Although laser slows growth, it isn’t always a permanent solution. It can take several laser treatments to provide an extended hair-free period, with several maintenance treatments required as well.
Electrolysis is the only system considered permanent by the FDA and AMA. (Source: WebMD)
