How does IPL work? The IPL hand piece delivers high intensity pulses of broadband light that is different from the narrow band light of lasers. IPL, which stands for intensed pulsed light, is non-ablative meaning that is does not damage the surface of the skin. The intense light is delivered to the deeper parts of the skin (dermis) and leaves the superficial aspect of the skin (epidermis) untouched. There are different versions of IPL available on the market that target different structures in the skin.
