1. A treatment system for modulating, approximating, or optimizing desired facial expressions by measuring personal degrees of expression of facial features in terms of Specific features, Relative distances, Elevations, Depression, Interacting features, and Coactivated distances (SREDIC) scores specifying expression intensity of individual Facial Expression Activated Markers (FEAMs) that are functionally classified and analyzed as personal relative distances between features, facial deformations and co-activated features before and after applying an agent or procedure to the face, head, or neck of a patient, the system comprising: a processor; a plurality of non-volatile program-memory locations coupled to the processor; a plurality of non-volatile data-memory locations coupled to the processor; a display device configured to be controlled by the processor; and, a camera configured to be controlled by the processor, wherein the plurality of non-volatile program-memory locations contains instructions that, when executed by the processor, cause the processor to perform operations comprising: receiving an image file of a full human face of a patient, the image file captured by the camera, the image file corresponding to a facial expression desired to be changed by the patient; sending for display on the display device the received image file; receiving, from the patient, information representative of a desired degree of change in the expression intensity of one or more selected Facial-Expression Activation Markers (FEAMs) of the facial expression desired to be changed; retrieving from the non-volatile data memory locations a SREDIC score that is associated with the selected one or more FEAMs, wherein the SREDIC score is based on personal relative distances between features, facial deformations and co-activated features of the patient associated with the selected one or more FEAMs, and corresponding facial muscles or facial muscle groups, wherein each of the corresponding facial muscles or facial muscle groups have an activation intensity level specified in terms of the degree and gradation level of FEAMs expressions; retrieving from the non-volatile data memory locations psycho-physiological states for which the SREDIC score is shared with, or functionally related to, the corresponding facial muscles or facial muscle groups of the retrieved SREDIC score; receiving image files of facial expressions corresponding with the retrieved psycho-physiological states; and generating, in response to the SREDIC score, the retrieved expressions of psycho-physiological states, and the received desired degree of change in the expression intensity, a treatment program comprising one or more treatments at one or more treatment locations for approximating the desired facial expression while producing optimized corresponding changes in the expression of each of two or more psychophysiological states, each of the one or more treatment locations targeting one of the one or more selected FEAMs and corresponding facial muscles or facial muscle groups, each of the one or more treatment locations having an associated treatment and dosage information for each FEAM.
