1. A system for changing an appearance of at least one frexel within a region of human skin of a first person, the system comprising: at least one reflectance modifying agent application element, the reflectance modifying agent application element being operable to selectively apply one or more reflectance modifying agents to frexels of the human skin; and a computing environment that is coupled to the at least one reflectance modifying agent application element and that is operable to perform operations comprising: obtaining a digital image feature map that provides data regarding at least one desired feature, scanning the region of human skin to generate a frexel feature map that identifies at least one feature associated with the first person, comparing the digital feature map and the frexel feature map to generate a reconstruction image, the reconstruction image comprising enhancement data, and instructing the at least one reflectance modifying agent application element to apply the one or more reflectance modifying agents to the at least one frexel based on the enhancement data such that the at least one feature associated with the first person appears more like the at least one desired feature.
