1. A device for stimulating a zone of human skin comprising an applicator having a head for confronting the skin, plural solenoids disposed on said applicator in an array in the vicinity of said head, each of said solenoids having a plunger that comprises a tip end which projects away from said head for imparting stimulus to the skin by repetitively impacting the skin in response to the repetitive energization and de-energization of the plunger'"'"'s solenoid, said device comprising an electric circuit board assembly containing electric circuitry thereon for repetitively energizing and de-energizing each of said solenoids, means for supplying electric power to said electric circuitry, and said electric circuitry comprising plural solenoid drivers each of which is individual to an individual associated one of said solenoids for selectively energizing and de-energizing the associated solenoid independently of the energization and de-energization of the other solenoids by their solenoid drivers, and means for operating said solenoid drivers in at least one mode of operation which is other than one in which all solenoids are simultaneously energized and de-energized in unison, and further containing D.C. battery means providing a self-contained electric power supply for operating said solenoids via said electric circuitry, said applicator comprising a hand-held housing containing said head, said solenoids, said electric circuit board assembly, and said D.C. battery means, and in which said head and housing are both electrical conductors that are electrically separated by an insulator, and said device contains touch switch means that is connected respectively to said housing and to said head and that is actuated by a conductive path through a user'"'"'s body when the user grasps the housing and places a portion of the head in contact with the skin, and in which said touch switch means is operatively connected with said electric circuitry such that when said touch switch means is so actuated, said solenoid drivers are operated by said electric circuitry.
