Technology history
Brief introduction of Laser Depilation
v Theory of laser depilation—Based on the theory of selectivephotothermolysis theory 
v The first laser type applied to depilation— ruby laser, approvedFDA certification in 1995.
v Alexandrite laser, long pulse 1064nm
v Diode laser for depilation
v —- 810nm diode laser by stampoperation
v —- Sapphire cooling painlessdiode laser by press-on fast sliding operation
810nm diode laser
Golden standard for Hair Removal 
810nm laser is absorbed by melanin in follicle mostly( penetration depth)
Assure epidermis safety
Greatly reduce the laser absorption by water and haematoglobin
810nm diode laser has simple structure, excellent effect and low side effects
