Light energy is taken in by the melanin within the hair and heat is generated. The heat then performs out towards the germ cells. As long as an adequate temperature level is preserved for the needed time then these cells will be successfully ruined. This is definitely crucial achieving the needed temperature is not adequate unless it is kept at that temperature for the matching time.




To attain these conditions the laser/IPL system should have the ability to generate the required power output. The primary reason that hair elimination stops working is just due to the fact that the devices can not create the wanted temperature level for the proper time. Spot size, or the width of the laser beam, directly impacts the depth of penetration of the light energy due to scattering results in the dermal layer.


Hair elimination lasers have an area size about the size of a fingertip (318mm). Fluence or energy density is another crucial consideration. Fluence is determined in joules per square centimeter (J/cm). It is necessary to get dealt with at high enough settings to warm up the hair follicles enough to disable them from producing hair.


3 kinds of cooling have actually been developed: Contact cooling: through a window cooled by flowing water or other internal coolant.

Sapphire windows are a lot more conductive than quartz.


These 3 criteria determine what really takes place when the light energy is absorbed by the tissue chromophore be it melanin, hemoglobin or water, with the amount of tissue harmed being determined by the temperature/time combination.

Unwanted adverse effects such as hypo- or hyper-pigmentation or, in extreme cases, burning of the skin require a change in laser choice or settings.
