Introduction to Laser Hair Removal.

The laser emits an light which penetrates the skin without damaging it. It is then absorbed by the pigments of the pilous follicle. The laser light selectively absorbed by the follicle damages its functions and impairs its ability to fabricate hair. At the level of the pilous follicle, the laser light absorbed by the pigments is then transformed into heat which damages the hair but not the surrounding skin. Laser hair removal is an effective and proven method. One generally speaks of extended periods of hair removal, with a decrease in the amount of hair and in their diameter. Thus, after each session and according to the area of the body involved, one can notice increasingly long periods in-between hair removal sessions (4-6 weeks at the beginning and several months after some sessions). On the whole and after several sessions, hair removal is virtually complete. It is imperative to stay away from the sun in the weeks preceding a hair laser removal session, since tan is a contra-indication for the treatment. People under medication must warn their doctor since some drugs can lead to reaction to light and require postponement of the laser treatment. Each impulse of the laser treats a surface of approximately two square centimeters with ten hairs. The duration of each laser session will depend on the surface of the area to be treated. Hair removal on small areas like the lip or the chin takes a few minutes, whereas the treatment of a wide area like a leg or a thigh requires between twenty to fifty minutes.
