I'm looking for a place in or near the North Jersey area.
Answer:The site http://www.HairRemovalForum.com has some good options that are in or near NJ. Additionally the attached site rates laser hair removal locations around the country.
The primary principle behind laser hair removal is selective photothermolysis. Lasers can cause localized damage by selectively heating dark target matter, in the area that causes hair growth, while not heating the rest of the skin. Light is absorbed by dark objects, so laser energy can be absorbed by dark material in the skin (but with much more speed and intensity). This dark target matter, or chromophore, can be naturally-occurring or artificially introduced.
