PL treatment uses light energy to target a certain color in your skin. When the skin is treated with heat, your body gets rid of the unwanted cells, thus getting rid of the skin concern for which you’re being treated for. Unlike lasers, an IPL device sends out more than one wavelength of pulsating light. It can treat a range of several skin conditions all at once. You will look more refreshed and more youthful because of a more even skin tone.
