Fractional RF delivers accurate Bipolar RF energy to the skin by a tip built of an array of small pins and returns electrodes to create microscopic thermal zones (MTZ). The RF energy introduces fractional thermal into the deep dermis and creates potential healing effects in the microscopic thermal zones. Undamaged tissue between the electrode pins acted as a “healing server” to accelerate the collagen rebuilding and skin tissues remodeling. Unlike the traditional laser therapy, the majority of the fractional RF energy is focused in the dermis while only a small percentage of the surface is affected, resulting in deep volumetric dermal heating and ultimate result. On the contrary, laser stays large volume on the surface, while only a small amount of energy penetrates deep into the dermis.
