The word laser is short form of light amplification by stimulated emission of radiation. A laser is a beam of light of single-wavelength which can be precisely focused to pass on that light on to a very small area.
Types of laser
There are two types of lasers that are used in cosmetic surgery procedures; ablative and nonablative laser. Ablative laser works on the upper layer of skin and wears it away while nonablative laser has nothing to do with the top layer of skin. It works in deep skin layers and the upper layers remain intact. Thereby, cosmetic procedures that use solely nonablative laser do not offer significant downtime and much pain.
How laser works
Lasers work through selective photothermolysis that is; it regulates frequency of light to produce heat in the specific area of the corresponding object you wish to destroy. When the surgeon points laser to the desired area of skin this light is absorbed by pigment in skin (melanin) and heat energy starts working there.
