Hyaluron GR Pen is a professional tool for needleless mesotherapy injections. Its modern design and simple operation make it an ultra versatile instrument.  This needleless hyaluron pen is an innovative device that uses pressurized air to inject a liquid hyaluronic acid (or any other beauty serum) through a narrow opening into human skin.By means of a spring system, the potion is introduced at high speed through a small orifice in the nozzle, creating a thin jet stream of fluid that easily penetrates the skin. Then the serum diffuses under the epidermis into the subcutaneous tissue.
