The MFRF device creates microzones of coagulation in the papillary and reticular dermis with minimal damage to the epidermis. RF emission delivered over the whole needle length allows better coagulation and heating of higher volumes of dermal tissue. Its action stimulates the skin’s self-repair system, to increase metabolism, improve microcirculation, the formation of new collagen elastin and hyaluronic acid and rearrangement of existing collagen fibers. The stimulus, open the pores to promote an absorption channel for active ingredients such as sterile meso solutions across the skin = Dermo infusion. The radio frequency energy emitted by the micro needles tip can selectively destroy the hair follicles, sebaceous glands and sweat glands, inhibit inflammatory reaction and activate the anti-inflammatory and repair system, helpful in acne control.
