The aforementioned circuit comprises elements such as an initiation device, a receptacle (5) containing an active agent to be injected, and an active agent injection system. The inventive method is characterised in that it comprises a step in which a gas-generating cartridge (6), which is adapted to the nature and/or quantity of active agent to be injected as well as to the skin penetration depth desired for same, is inserted directly into the circuit of elements, independently of said elements, from outside the body (2).
