Claim:
1. A system to inject a medium into or underneath the skin with a series of pressure pulses, comprising: a reservoir for the medium, a hose comprising a pressure reservoir; a handheld application unit spatially separated from the reservoir and configured to inject the medium into or underneath the skin via a controllable injection nozzle, comprising: a hydraulic high-pressure pump configured to receive the medium from the reservoir and pump the medium into the application unit via the hose, wherein the hose connects the reservoir and the application unit, an electronic control unit configured to control the application unit and the movable nozzle needle such that the medium is injected into or underneath the skin with a series of pressure pulses, wherein the injection frequency and thus the quantity of the medium injected per unit of time is controllable via the electronic control unit and opening and closing the at least one exit hole in the at least one injection nozzle by the movable nozzle needle, and a pressure limiter located fluidically between the application unit and the high-pressure pump, wherein the pressure limiter is controllable by at least one of the control buttons and the electronic control unit to adjust the injection pressure of the medium and thus the injection depth of the medium into or underneath the skin.
