In order to synthesize attractive facial expressions, it is necessary to consider detailed expression changes such as facial wrinkles. Nevertheless, most techniques of expression synthesis (i.e. blend shape, image morphing, simulation of mimic muscle and so on) focus entirely on large-scale deformation of a face and ignore small-scale details such as wrinkles and bulges. Therefore, hand crafted work of skilled artists is inevitable to make a face attractive finally, unless using a huge photographic equipment.
