Skin type 1
Redhead / blonde
Amount of time required for a given heated tissue to lose 50% of heat through diffusion
Thermal relaxation time
Measured in Hz number of pulses per second
Repetition rate
Target takes in the light
Absorption
Some of the light will bounced off the tissue
Reflection
Light passes through some layer of tissue
Transmission
After absorption energy becomes weaker until harmless
Scatter
Permanent hair removal
electrolysis
When one chromophores blocks another
Chromophore shielding
