Abstract
A computer-controlled system determines attributes of a frexel, an area of human skin, and applies an electrostatically charged modifying agent (RMA) at the pixel level, to make the skin appear more attractive. The system scans the frexel, identifies unattractive attributes, charges the RMA with an electrostatic charger, and applies the RMA, typically with an inkjet printer. The identified attributes relate to reflectance and may refer to features such as irregular-looking light and dark spots, age-spots, scars, and bruises. Identified attributes may also relate to the surface topology of the skin, for more precisely enhancing surface irregularities. Feature mapping may be used, for example to make cheeks appear pinker and cheekbones more prominent. The charged RMA can be applied in agreement with identified patterns, such as adding red to a red frexel, or in opposition, such as adding green or blue to a red frexel, according to idealized models of attractiveness.
