WHAT IS IPL? (IPL) INTENSE PULSED LIGHT uses light to heat hair follicles and prevent regrowth. Essentially, the energy heats the hair – right down to the bottom of the root – safely destroying it without damaging surrounding tissue or skin. “This process is also called photo thermal destruction IPL works in a similar way to laser therapy. The difference is that where laser therapy delivers a single wavelength of light energy, IPL delivers multiple wavelengths. This means that IPL can treat a larger area of skin in a shorter time than laser therapy.  When used for hair removal specifically, IPL usually requires six to eight treatments to see a complete removal of hair in an area.
