MNRF is also called Micro Needling Radio Frequency. MNRF is a simple, safe, effective, and minimally invasive therapeutic technique. Needles are introduced in the skin with a preselected depth. RF is delivered through these needles to heat the dermis. RF is color blind hence can be used in any skin type safely with excellent results.
RF was being used in dermatology since early 2000. Micro-needling dates back to 1995 when Orentreich and Orentreich described dermal needling in the form of subcision for scar treatment. Hantash and colleagues in 2009 proposed the concept of using needles as electrodes which allowed the RF energy to be delivered into the dermis.
Radio-frequency is a high frequency alternating electric current. When an electric current flows through the body, the body offers resistance to its flow. This resistance of tissue is known as impedance. Joule’s law states that when electric current meets resistance, heat is generated due to the micro-oscillations of charged particles.
When the temperature of tissues rises to about 60 degrees, tissues get coagulated. RF effect is electro-thermal. Depth of penetration of RF is inversely proportional to the frequency of RF.
