Intense-pulsed Light (IPL) Technology

The advent of IPL devices in the early 1990s signalled a paradigm shift in the concept of light-based skin rejuvenation including treatment of many acquired superficial pigmentary disorders. Instead of targeted removal of a single skin lesion by specific laser light, the use of an intense, pulsed, broadband light emitted by a non-coherent flashlamp with filters to modulate the wavelengths allowed for simultaneous treatment of multiple skin blemishes.

IPL devices are effective in treating superficial vascular, pigment-related lesions and unwanted hair. IPL devices with different cut-off filters and pre-programmed parameters have resulted in safer and easier skin procedures. The term "photorejuvenation" was coined to describe the simultaneous improvements in brown spots, red spots, and fine wrinkles with IPL devices (Bitter, 2000; Negishi, Tezuka, Kushikata, & Wakamatsu, 2001; Negishi et al., 2002; Negishi, Kushikata, Takeuchi, Tezuka, & Wakamatsu, 2006).
