The machine is the upgrade of IPL for skin rejuvenation and hair removal .The RF electrical energy and IPL optical energy together are used to achieve the heating required for selective thermal injury.Part of the heat required for selective injury to the target is produced by the fraction of optical energy contained in the electromagnetic pulse.This delivers effective heating and biologic effects at lower levels of optical energy.RF is not absorbed by melanin and thus independent of skin types.Hence, the machine reduces the risk of epidermal injury and increases dyschromia, particular with tanned, oliver-colored, dark and black skin.Moreover, the virtual absence of a target chromophore explains the failure of all light-based technology to achieve effective epilation of gray or blond hair.RF energy can heat the bulge and outer root of sheath of the hair follicle in the absence of melanin.
