A system and method for automatic reading skin for an allergy to a substance, includes a consumer electronics device that acquires images of skin; a consumable member having a surface divided into elementary areas, each elementary area with a different possible allergenic substance; and a palette that, when applied against each elementary area brings the depositing part into contact with the skin thereby depositing the corresponding possible allergenic substance on or under the skin, where an image processing operation of the image of the skin taken by the consumer electronics device localizes the location that each depositing part has deposited the possible allergenic substance during the application and provides information in relation with a sensitivity of the skin, as indicated by a visible reaction, to the possible allergenic substance at each localized location.
