Abstract: Improved undyed substrate formulations described herein have enhanced dye fixation and colorfastness due to opposite electrostatic charges between the base material and the dye. The substrate or base material is formulated to possess an electrostatic charge through the addition of one or more polar or otherwise charged ingredients. A printer device may be used to apply dye to the substrate formulations in a selected image, pattern, or color to produce a customized cosmetic having enhanced dye retention.

Abstract: A customized cosmetic system is provided. The system includes a dock and at least one cartridge containing a cosmetic disposed on the dock. The at least one cartridge or dock contains a mechanism for dispensing a metered or measured dose of the cosmetic. In some embodiments, the mechanism for dispensing a metered or measured does of the cosmetic is automated and configured to be hands-free. In some embodiments, a user collects and mixes the cosmetic in a base cosmetic disposed in the at least one cartridge. In some embodiments, a user applies the cosmetic directly onto a collection container.

Abstract: A device for producing a cosmetic composition is in the form of a printer that is modified to receive and process cosmetic components. The device includes a printer housing that includes at least one print head and an opening for receiving a substrate and allow positioning of the substrate in relation to the at least one print head. At least one replaceable cartridge is provided and contains a cosmetic substance. The at least one replaceable cartridge is operatively coupled to the at least one print head such that the cosmetic substance can be applied to the substrate through the at least one print head. The resulting cosmetic composition is made of at least one cosmetic substance and the cosmetic composition is a transferable material that can be removed from the substrate and applied to a part of a human body.
