Abstract: A process is disclosed for acquiring scanned image data relating to an external body portion and/or a product applied to the external body portion. The process includes placing a transfer member in contact with an external portion of an individual to obtain a transfer image on the transfer member. The transfer image of the transfer member is scanned with an optical image scanner to obtain scanned image data. The scanned image data may be sent from a first computer associated with the scanner to a second computer at a remote location. An image corresponding to the scanned image data may be displayed and viewed to analyze a characteristic of the external body portion and/or a characteristic of a product applied to the external body portion. The process may also involve determining a recommendation of a treatment for the external portion and providing this recommendation. Another aspect relates to evaluating the product applied to the external body portion.

Abstract: A method of enabling evaluation of a typological characteristic of an external body portion of an individual comprises generating a sequence of images simulating varying degrees of at least one typological characteristic of an external body portion and enabling identification of at least one image within the sequence of images that substantially corresponds to a typological characteristic of the external body portion of the individual.

Abstract: A method of determining an individual's level of tolerance to application of a cosmetic product to skin of the individual may include: applying a substance onto a test zone of the skin, the substance containing at least one agent for stimulating the peripheral nervous system; exerting a mechanical action on the test zone of the skin to reduce a barrier function of the skin relative to the substance; and observing any reaction of the individual as a result of applying the substance. The substance may be the product itself and/or may be configured to produce a reaction representative of an undesirable reaction that might be observed after application of the product. The mechanical action may be exerted at least one of before, during and after application of the test substance.

Abstract: The present invention provides a method of evaluating a physical condition or a magnitude representative thereof. The method comprising: obtaining data for quantifying at least a first body state and a second body state that are different; and evaluating the physical condition or a magnitude representative of the physical condition by applying weighting coefficients or a segmentation tree to the data as obtained in this way. The coefficients or the tree are previously determined by statistical analysis on a group of reference individuals.

Abstract: The present invention relates to a system for analyzing the skin of a subject, the system comprising: a camera for acquiring at least one image of the skin at a magnification that enables the pores and/or the spots of the skin to be observed; a display device for displaying simultaneously at least one acquired image and an image of a reference skin; an apparatus other than a camera for measuring at least one physico-chemical characteristic of the skin; and a processor for delivering information relating to the state of the skin by processing at least one acquired image and/or a measurement performed by the apparatus.

Abstract: A method evaluating the typology of the region extending around the human eye and an apparatus that can perform the evaluation are provided. At least one data item is acquired concerning at least one zone of the region around the eye, with the data item being representative of a pigment present in the blood stream and/or a pigment outside the blood stream. In addition, at least one data item is acquired relating to the relief of at least one zone of the region and/or at least one mechanical property of at least one zone of the region. Based upon the acquired data, information relating to the typology of the region is provided.

Abstract: Systems and methods may facilitate evaluation of at least one degree of at least one characteristic of a substance. The systems and methods may generate at least one sequence of images expressing at least one characteristic varying in at least one degree, and receive information reflecting at least one identification of at least one image from the at least one sequence. The at least one image may correspond to at least one degree of at least one characteristic of a substance.

Abstract: A system for evaluating a characteristic of body typology, such as a characteristic of the skin or hair appearance.
