Hydra pen microneedling

Hydra pen microneedling devices are an electric microneedling device, also. But Hydra pen microneedling is different with Dr.pen microneedling. There's 5 mL serum capacity for Hydra pen needle cartridge. When you put the serum into the Hydra pen needle cartridge and do the skincare, the serum will come out at the same time. It's very convenient to do skincare with Hydra pen at home.
