A method for evaluating skin conditions on a skin area of a user using an ultraviolet light device that can connect to a mobile device and a user input is disclosed. The method for evaluating skin conditions includes the steps of illuminating the skin area of the user with the ultraviolet light device operated by the mobile device, capturing an image of the illuminated skin area with an image capture device, processing the image with a processing program to determine the level of fluorescence on the skin area, and mapping progress of treatment of the skin condition based on the processed image compared to a control image.

UV device for smartphone-based evaluation of skin conditions

A method is described that makes it possible to measure flushing, particularly in the context of the study of rosacea, and to distinguish normal flushing from pathological flushing. Also described, is the use of said method to study the effect of drug candidates, particularly against rosacea. The method can include: a) subjecting the subject to a flushing inducing stimulus; b) measuring the inflow of blood in the face of the subject during a time period covering the flushing; and c) calculating entropy of the inflow of blood.

Method for measuring flushing and use for assessing treatments

A method is described for analyzing images of the face of a human being. The method can include the following steps: &#x2014;acquiring at least one image of the face such that the nose, the eyes and the cheeks are aligned on pre-existing markers, &#x2014;determining the components of the image in at least one zone of the face, &#x2014;comparing the components to stored values, and &#x2014;determining the presence of a flush effect if the components are greater than the stored values.
