Abstract: Systems and methods for measuring spectra and other optical characteristics such as colors, translucence, gloss, and other characteristics of objects and materials such as skin. Instruments and methods for measuring spectra and other optical characteristics of skin or other translucent or opaque objects utilize an abridged spectrophotometer and improved calibration/normalization methods. Improved linearization methods also are provided, as are improved classifier-based algorithms. User control is provided via a graphical user interface. Product or product formulations to match the measured skin or other object or to transform the skin or other object are provided to lighten, darken, make more uniform and the like.

Abstract: An apparatus to realize a personalized cosmetic composition including a feeder to expose a base stored in a chamber, a dispenser to dispense a selected treatment mixture onto the base and form a treated base, a collector to collect the treated base from the chamber and depose the treated base onto a collection container, and a compacter to compact an accumulation of the treated base inside the collection container. The dispenser includes a plurality of reservoirs containing a plurality of additives to be selectively incorporated into the selected treatment mixture, wherein the plurality of additives includes a plurality of pigments to produce the selected treatment mixture in a selected of color.

Abstract: A system is provided including a styling tool configured to treat or shape a user's hair, and a client device configured to communicate with the styling tool and provide feedback to the user regarding a user's usage of the styling tool. The client device is configured to receive input information from the user regarding a desired result to be achieved using the styling tool, and to output guidance information on a method of using the styling tool to achieve the desired result.

Abstract: Devices and methods useful for sensing epidermal tissue are disclosed. Thermal data from the devices allows for determination of thermal transport properties, such as thermal conductivity, thermal diffusivity and heat capacity per unit volume. From these data, tissue parameters, such as hydration state, stratum corneum thickness, epidermis thickness and vasculature structure may be determined. These parameters may be used, for example, to evaluate the efficacy of dermatological compounds.
