Abstract
A system and method for use in determining skin dryness by processing images of a test patch of the kind comprising a membrane impregnated with a moisture indicator which has a first colour in the dry anhydrous state, and which changes to a second colour at a certain moisture content which corresponds to normal skin moisture are disclosed. A user operable computer device having a camera, a processor, and an area of memory, a computer program stored in the memory of the user operable device, a scorecard having at least one colour reference target in which the computer program causes the user operable computer device to process an image of the scorecard with a test patch placed on it after the test patch has been applied to an area of skin, the processing determining a dryness of the area of the skin.

A system for use in determining a skin dryness by processing images of a test patch of the kind comprising a membrane impregnated with a moisture indicator which has a first color in the dry anhydrous state, and which changes to a second color at a certain moisture content which corresponds to normal skin moisture, the system comprising:
- a user operable computer device having a camera, a processor, and an area of memory;
- a computer program stored in the memory of the user operable device;
- and
- a scorecard having at least one color reference target,
- wherein the computer program causes the user operable computer device to process an image of the scorecard with a test patch placed on it after the test patch has been applied to an area of skin, the processing determining the dryness of the area of the skin.
A system for use in determining a skin dryness by processing images of a test patch of the kind comprising a membrane impregnated with a moisture indicator, which has a first color in the dry anhydrous state, and which changes to a second color at a certain moisture content which corresponds to normal skin moisture, the system comprising:
- a user operable computer device having a camera, a processor and an area of memory,
- a computer program stored in the memory of the user operable device, and
- a scorecard having at least one color reference target, for example a first target which has a color that corresponds to a fully dehydrated test patch and a second target having a color that corresponds to a fully hydrated test patch and a region in which a test patch can be placed, and wherein the computer program causes the user operable computer device to capture an image of the scorecard with a test patch placed on it after the test patch has been applied to an area of skin and to transmit the captured image across a network to a remote server that is configured to process the image to determine a dryness of the area of the skin.
A method of determining a skin dryness by processing images of a test patch of the kind comprising a membrane impregnated with a moisture indicator, which has a first color in the dry anhydrous state, and which changes to a second color at a certain moisture content which corresponds to normal skin moisture, the method comprising:
- capturing an image of a test patch that has previously been stuck to an area of skin together with an image of a scorecard, the scorecard having at least one color reference target and a region in which a test patch can be placed;
- processing the captured image to identify the color reference target and the patch;
- calibrating the colors in the captured image using the colors of the captured target;
- and
- analyzing the image of the patch in the captured image to determine the percentage of the patch that has the first color and the second color.
A scorecard for use in combination with a test patch of the kind comprising a membrane impregnated with a moisture indicator, which has a first color in the dry anhydrous state, and which changes to a second color at a certain moisture content which corresponds to normal skin moisture, the scorecard comprising:
- a backing portion;
- and
- at least one color reference target, wherein the backing portion includes a region that is sized to receive a test patch.
