Training - The Difference Between IPL and Laser
It’s vital to learn how laser hair removal works in able to have realistic expectations with the treatment. Learning how an IPL and a laser work on the skin will also help you choose the kind of treatment that fits your concern. In this training, the difference between IPL and laser will be exposed. So you can understand why a laser is more effective than IPL when it comes to laser hair removal.
Difference between IPL and laser
According to Wikipedia, IPL or Intense pulsed light (IPL) is a technology used by cosmetic and medical practitioners to perform various skin treatments for aesthetic and therapeutic purposes, including hair removal, as well as to alleviate dermatologic diseases.
IPL is a glorified torch, equipped with different filters to block the light when selecting targets. IPL heats the pigment in the skin that may cause burns in the superficial layer.
Due to its broad spectrum of wavelength, there is a high risk of burning the epidermis when IPL is used for hair removal. IPL has different lengths, depths and filters, depending on its use. The kind of IPL that will be used varies depending on the target. For instance, a different IPL is used when targeting a hair, and when targeting veins.
Laser or light amplification by stimulated emission of radiation. According to Wikipedia, it is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.
A laser differs from other sources of light that it emits light coherently. Spatial coherence allows a laser to be focused to a tight spot. Lasers can also have high temporal coherence, which allows them to emit light with a very narrow spectrum.
A laser produces one single wavelength, a concentrated beam, which targets the melanin follicle. A diode laser with 800 nm is the specific length that can target the hair shaft. Because the laser works solely to remove hair, it is safer for treatment, and it works better for darker skin. With its concentrated beam, a laser does a quicker, longer lasting job than other IPL.
How laser hair removal works
Selective photo-thermolysis is the mechanism for laser hair removal. This treatment uses selective laser, which means it only affects the targeted hair and not the surrounding skin or tissue. With the laser’s selective chromophore technique, it works by targeting the pigment of the hair, and the melanin of the hair shaft where the laser is absorbed.
Photo means the laser sends amplified light that penetrates the target area, which produces heat (thermo) that is delivered to the skin and to the base of the hair shaft.
Once the laser selectively targets the hair, and light produces heat to the area, it will result in the destruction or lysis of the active hair follicle. The laser will heat the hair up to 70 degrees, which can permanently destroy the hair, and make the active hair follicle and hair shaft dormant.
