Intense pulsed light (IPL) is a non-invasive treatment used by medical practitioners to perform treatments for aesthetic and therapeutic purposes. It can be used on any part of the body. It is similar to laser treatment but a laser focuses on just one wavelength of light while IPL releases light flashes of many different wavelengths. The light from IPL is less focused than a laser. IPL penetrates down to the second layer of your skin (dermis) without harming the top layer (epidermis), so it causes less damage to your skin than a laser.
