laser
"Many opinions float as to Laser being better than IPL. Laser is a different technology in the sense that distributes, or to be politically correct, concentrates the beam in one place versus IPL spreads it out to a wider surface. Think of it this way, laser is like a hose poring out water concentrated in one place but IPL is like the spayer we use to water our plants, it covers a wide area."
"I recently heard a metaphor that simply illustrated the difference between IPL and Laser. IPL, I was told, is like the sun. Laser is like that sunlight passed through a magnifying lens. The light and heat is much more intense using the lens "
"Every day, we encounter low-level laser used in security and scanning devices like you might find at a supermarket checkout counter. These lasers are safe. The word 'laser' is like the word 'transportation'. There are many types of lasers just as there are many types of transportation. The difference between Low-Level Laser used in health applications and High-Powered Laser used in industrial applications can be equated to the difference between a passenger car for transportation and a jumbo jet for crossing the continents."
"A laser is like a zamboni for your body, buffing you smooth for a pick-up hockey match."
