Toppan Printing, a provider of touch display solutions, communication, security, packaging, décor materials and electronics solutions, is collaborating with Kose Corp., a beauty and personal care company, to leverage data from facial scanning to examine differences in skin appearance through optical simulations of layers of cosmetics.

Testing is being conducted at the recently launched Toppan Virtual Human Lab, which researches the application of information on the human body and is equipped with a Light Stage device developed by the University of Southern California for high-definition facial scanning, according to a press release. Some testing is also being performed at USC's ICT Vision & Graphics Laboratory, and due to be completed by the end of this month.

The companies seek to develop services making use of virtual spaces to support counseling and product selection matched to the characteristics of each person's skin.

The COVID-19 pandemic has limited opportunities for face-to-face contact and counseling with customers in stores, and in many cases testers have been removed from display shelves, making it harder for consumers to select the best product for their needs.

3D computer graphic data is generated from the results of high-definition facial scanning using the Light Stage device, which controls multiple light sources in a spherical dome for high-definition scanning of face shape and texture.

The data is then used as the basis for examining the effectiveness of counseling and optical simulation of layers of cosmetics. Toppan is handling facial scanning, 3D computer graphic data generation, cosmetics information mapping and development of a makeup simulator. Kose is providing test participants for the Light Stage, supplying Toppan with information on cosmetic products and advising on the tuning of the simulator.
