Treatment theory Elos(electro-optical synergy) is a combination of IPL(intense pulse light) and RF(Radio Frequency).The RF electrical energy and IPL optical energy 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 electromagnetic pulse.This delivers effective heating and biological effects at lower levels of optical energy.RF is not absorbed by melanin and thus independent of skin types.Hence,the equipment reduces the risk of epidermal injury and increase dyschromia,particular with tanned, olive-colored,dark and black skin. Moreover, the virtual absence of a target chromophore explains the failure of all lightbased 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.
