Intense pulsed light is not a laser per se. This is an intense light source. What makes IPL different from a laser is that it fires a broad, high-intensity pulse of light at the skin, rather than a more invasive, finely calibrated laser beam set at a narrower, specific wavelength. In other words, IPL operates over a wider range of wavelengths, and thus a single machine can handle more than one condition using the specific filters that are required for a particular problem. Therefore, if the clinic or spa has an IPL machine, then various skin conditions can be safely treated, as well as hair removal, while lasers operate in a narrow wavelength range. The disadvantage of IPL is that while each individual treatment is claimed to be less expensive, safer, and gentler than laser, it is also less intense and results are not as pronounced. Therefore, more sessions may be required to obtain the desired results. Another consideration that may or may not influence the decision to undergo photorejuvenation is the paucity of studies examining the long-term effects of IPL treatment. Please also note that a number of restrictions must be observed before undergoing the procedure, as well as after the session, in order to maximize results and minimize any potential side effects.
