Hydra Pen H2 is the latest upgrade model of traditional microneedling device. The design of the H2 cartridge is unique as H2

cartridges are able to contain face serum. Serum in the cartridge will spread to the skin surface automatically while the device is

working. It's convenient for users to control the device and serum at the same time with one hand. H2 has a 4-speed driver and a

digital display screen as well. It's your best choice to do needling at home.
