Lasers emit energy in the form of light and the laser heats up the hair follicle.
The light from the laser is then attracted to and absorbed by melanin, the pigment in your hair.
The heat travels down the hair before destroying the root and connections to the blood supply, therefore preventing the growth of further hair.
The treatment provided by Aesthetics of Essex only targets the structures of the hair and follicle the surrounding tissue is left undamaged.
