Perhaps you're right. Though I think the hardware you may be envisioning is different from ours. In the consideration for lipstick application, this device isn't meant to be a robotic copy of a human arm applying various cosmetics a la the jettisons. The goal is to provide makeup application: general cosmetics to specific regions of the face in a given order. From this you can develop cosmetics that can be applied via airbrush and perhaps another applicator (gel, or inkjet) that render this effect. One does not need to stick to conventional solid lipstick nor it's means of application to achieve the desired look of red upon lips. Granted there is mention of kinematics which implies robotic arms and that design path is still a consideration, but recently we have trended towards a means of application via a moveable applicator head attached to rails and guides similar to 3D printing. As provided in previous links, airbrush is already used for applying foundation, lips, eyeshadow and blush. https://en.wikipedia.org/wiki/Airbrush_makeup https://en.wikipedia.org/wiki/Airbrush_makeup
