Aspects of interest in hair depilation
For laser hair removal define what our goal. If we want a permanent hair removal or long-term, we must act on the hair follicle destroying the bulb, or more specifically, cells that give rise to hair.
To do this we will build on the fact that this whole area has a lot of melanin, while the skin has less melanin. Therefore, the laser is absorbed very selectively by melanin, and in very few of the other components of the skin.
The laser must penetrate enough to act effectively. Not all lasers used in hair removal have the same penetration, depends, as we have said, the nature of the radiation they produce. The important thing for us is that when the laser hits the target (melanin) its energy is absorbed and converted into heat.
As in any local application of heat to the body, immediately there is this heat dissipation by different organizational structures, and therefore, a cooling until it reaches body temperature.
The purpose of the Laser hair removal is achieved in the target area the temperature needed to destroy cells pilo sebaceous follicle matrix. This temperature is around 70 ~ 80 degrees.
The problem is getting time this temperature by the laser.
