Q-S Infinity Pro emits 1064 nm wavelength (optimal on epidermis), which thanks to the glass of titanyl potassium diphosphate (KTP) becomes to 532 nm wavelength (effective on dermis). This frequency doubler allows changing wavelength from 1064 nm (infrared) to wavelength of 532 nm (green) giving to the QS-Nd: YAG / KTP two wavelengths into one compact system.This high energy in such a short space of time produces a photoacoustic effect with mechanical shock on tissues focused to fragment the pigment. The pigment is removed by three possible mechanisms when the Q-switched laser is applied on the skin:
- Fragmentation of the pigment in small particles (less than 6 microns) to facilitate elimination through phagocytosis via lymphatics.
- Chemical alteration of the pigment it less visible to the human eye.
- Pigment can be decreased to some extent by the trans epidermal elimination.
