High Output Intense Pulsed Light System. The SPL800 produces an industry-leading 220Jcm2 energy density at 410-800nm (broad based light) with a pulse duration of 0.1 seconds. Pulse frequency is user-adjustable from 1-7 emissions per second. It has the ability to treat more aggressively than the SPL600, giving the extra punch for those very suborn hairs. It will also effectively treat light inks (flesh tones) whereas the SPL600 cannot. This system is also excellent for general dermatology procedures, age spot removal, wrinkle reduction, laser resurfacing and more.
