Why Is Lyra The Best Solution?

Lyra's laser beam passes through the skin and is absorbed in the hair follicle residing underneath the skin's surface.  The laser energy destroys the follicle with the heat that it generates.  Destroyed hairs are then either dissolved within the skin or ejected by the body.

Because the laser beam is larger in diameter than the hair follicle, a large number of hairs can be treated simultaneously.
