This invention describes a device that operates like a specialized printer, but instead of printing ink, it dispenses cosmetic substances from replaceable cartridges onto a surface. The device uses print heads to apply these substances, which can include multiple colors, to create a custom cosmetic mixture directly on a substrate. This finished cosmetic can then be peeled off the substrate and applied to the body.
Why it matters: Filed before significant advancements in microfluidics and material science for 3D printing, which could now enable more precise dispensing and layering of diverse cosmetic formulations. These advancements could also improve the adhesion and transferability of the final cosmetic composition from the substrate.
