Abstract: A portioning machine for providing a custom cosmetic includes a mixer having a mixing chamber and also accommodates a plurality of syringes having outlets that are directly coupled to the mixing chamber. In one embodiment, the portioning machine includes a plurality of slots, where each slot is configured to receive an assembly having at least one syringe. In another embodiment, the portioning machine includes a slot configured to receive an assembly having a plurality of syringes. Each syringe is associated with an actuator, and the portioning machine includes a portioning processor configured to control the actuators to dispense additives from selected syringes into the mixing chamber in accordance with a target set of additive ratios to produce the custom cosmetic.

Abstract: A cosmetic portioning machine is provided having a mixing chamber, with a plurality of inlets each of which provides an ingredient. A piston disposed in the mixing chamber to define a mixing volume. A dasher is disposed in the mixing chamber and mixes the ingredients together in the mixing volume so as to form a cosmetic. When the cosmetic product is thoroughly mixed, the piston urges the product out of the mixing chamber and through an outlet. A moveable sealing member is configured to pass through the outlet so as to seal off fluid communication between the mixing chamber and the outlet and to urge any remaining cosmetic product through the outlet.

Abstract: A system and method determine color of skin of a subject and produce a customized cosmetic based at least in part on the determined color of skin. A region of skin is covered with a chamber having an open area facing the skin. The skin is illuminated with light caused to enter the chamber. The light is caused to be dispersed within the chamber. A camera is used to record an image of a portion of the dispersed light in the chamber and the recorded image is processed to characterize the color of the skin. The recorded image includes a plurality of colors which are mapped to the closest color recipe. The color recipe is used to calculate actuator displacements for a portioning machine that includes a cartridge having cosmetic additives that produce the customized cosmetic.
