Fractional RF or laser delivers energy in a matrix way to create a Micro Thermal Zone. The energy introduce fractional thermal into the deep dermis and create potential healing effects in the Micro Thermal Zone. Undamaged tissue between the electrode pins acted as a “healing server” to accelerate the collagen rebuilding and skin tissues remodeling, thus to achieve results of Improving the pores, acne scars, skin texture, fine lines and wrinkles.
