IPL stands for Intense Pulsed Light and uses a source of broad-spectrum, visible light. This light is specially controlled to remove shorter wavelengths and devised to target specific structures. In hair removal, it is designed to target the melanin pigment in the hairs, while in other uses such as the treatment of spider vein it targets the hemoglobin in the blood. The light energy is absorbed, transferring as heat energy which warms the hair, causing damage to the follicle.
How does it work?
Benefits Of IPL Hair Removal
As broad-spectrum light naturally spreads out, the coverage of IPL hair removal devices is greater than laser hair removal devices. It, therefore, may mean that treatment times may be quicker because larger areas can be treated at once. As well as treatment times being quicker, they may also be considerably cheaper, but you may find that you need more sessions to achieve the same results.
IPL uses a broad spectrum of light, which means it can have different uses. It can be used to treat a variety of different skin conditions very successfully. It can also be altered specifically to match different skin and hair types within a treatment type. For example, a variation of IPL called VPL, which stands for Variable Pulsed Light, has been developed. VPL enables the user to modify the settings of the light pulses to best suit the skin and hair they are aiming to treat. This is because the developers recognize that not only do different skin tones have different requirements for light-based hair removal devices and also that thick, course bikini line hair will require different treatment to thinner arm hair.
