The gadget has been showcased at CES 2025, in partnership with NanoEntek, a South Korean startup that specializes in chips that can understand biofluids. The French cosmetics multinational is taking a cutting-edge approach to meet the demand to slow down the aging process, with the launch of Cell Bioprint.
