The invention pertains to a delivery device for controlling the injection of discrete quantities of fluid injectable materials through a conduit such as a hypodermic needle or a catheter. The delivery device is coupled to a pressurized driving fluid source, and the control means provides controlled passage of pressurized driving fluid into a syringe body to act against a piston which forces the fluid injectable material out the needle or catheter. In addition to the delivery device, the invention includes a needle depth guide which is preferably used in combination with the delivery device for cosmetic applications when a hypodermic needle is used to deliver a fluid injectable material to the dermis.
