Fractional Micro-needle RF System is a device in which a micro needle is directly inserted into the dermal layer of the skin and applies RF to the periphery of the needle surface. Secret is a device that repairs the skin. You can see the coating effect by collecting energy by extending one RF energy for a long time. It is a system that can be applied to various skin types prior to abnormalities such as PIH caused by heat damage to the epidermal layer, and the downtime is dramatically faster compared to laser.
