Integrated design, more convenient to use.Compared with the traditional microneedle use procedure, it is necessary to apply the relevant essence after the microneedle is finished. HR64 simplifies these two steps into one step, and evenly applies the essence while using the microneedles. It is more convenient to use and saves time. 2. Spread evenly and increase absorption. Each needle can bring the essence into the cortex, which can maximize the effect of the essence, while also reducing unnecessary waste of the essence. The flow rate of the essence can be controlled by different pressing forces. 3. Widely used and safe and effective. Suitable for all people, can be used at home or in clinical use. It is recommended to be used once and to ensure more safety and hygiene.
