laser hair removal

| |
Excellent results have been reported for laser hair removal on various body parts, with results achieving optimal hair removal of about 60-80% in just two or three sessions. Also, after the treatment, when the hair grows back, it tends to be finer and sparser. Results improve through repeated treatments as only 20-30% of hair follicles are susceptible during one laser application. Lasers can stop hair growth by selectively heating dark target matter (melanin) in the area that causes hair growth while not heating the rest of the skin. Laser and light-based methods are also called photoepilation. The process of laser hair removal works by directing the laser onto the skin, where the laser high-energy light becomes absorbed by melanin located in the hair follicles.
Once absorbed, the light transforms into heat, destroying the entire part of the follicle responsible for the growth of new hair. The laser is usually pulsed, or "turned on", for only a fraction of a second, and the duration of each pulse is just so long that enough light and energy is absorbed by the follicle to destroy it, but not long enough that excess heat is transferred to the skin surrounding the hair follicle. The result of this process is more selective hair follicle damage and less skin damage.
If operated by the right clinician, contemporary lasers are capable of vastly reducing complications by adjusting the laser to prevent possible blistering and pigment changes in some people.
