Abstract
A colorimetric sensor for pH measurement may be used (e.g. litmus paper, microfluidic device with chemistry for colorimetric pH measurement) to collect sweat pH information from a subject. An application is provided on a computing device that detects and analyzes the color change in order to determine the pH of sweat detected by the colorimetric sensor. Based on the determined sweat pH values and questionnaire responses, the application may recommend a skin regimen/treatment to restore skin function. The application may also provide visualizations of predicted effects of the skin regimen on a skin condition of the subject.
Claims18
A system for generating predictive visualizations of a result of a skin treatment regimen, the system comprising:
- a server computing system comprising one or more computing devices;
- at least one physical collection device configured to produce a color indicative of a sweat pH of a subject on whose skin the physical collection device is placed;
- and
- a mobile computing device comprising:
- at least one processor;
- a display device;
- a camera;
- and
- a non-transitory computer-readable medium having computer-executable instructions stored thereon that, in response to execution by the at least one processor, cause the mobile computing device to:
- capture an image of an area of interest of the skin of the subject;
- capture an image of the at least one physical collection device;
- determine the sweat pH of the subject by analyzing the color produced by the physical collection device;
- and
- transmit the sweat pH and the image of the area of interest to the server computing system;
- wherein the server computing system is configured to:
- determine a skincare product recommendation based on the sweat pH;
- generate a visualization indicating a result of applying the skincare product to the area of interest based on the sweat pH, the image of the area of interest, and the skincare product;
- and
- transmit the visualization to the mobile computing device;
- wherein the instructions further cause the mobile computing device to:
- receive and present the visualization to the subject.
A method for treating a patient with a skin condition associated with high sweat pH, the method comprising:
- determining a sweat pH of skin of the patient by:
- applying at least one physical collection device to the skin of the patient, wherein the physical collection device is configured to produce a color indicative of the sweat pH of the skin;
- and
- using a mobile computing device to determine the sweat pH by performing a colorimetric analysis of an image of the at least one physical collection device captured by the mobile computing device;
- determining a recommended skincare product to treat the skin condition based on the sweat pH;
- and
- topically administering the recommended skincare product to the skin.
A method of generating a rendering of a face image to indicate a result of a skin treatment regimen, the method comprising:
- capturing, by a mobile computing device, a first image of a physical collection device applied to a skin area of a subject, wherein the physical collection device changes color in response to a pH of sweat excreted by the skin area;
- capturing, by the mobile computing device, a second image of a face of the subject;
- determining, by the mobile computing device, the pH of the sweat excreted by the skin area based on the first image;
- determining, by the mobile computing device, a recommended skincare product based on the sweat pH;
- determining, by the mobile computing device, a predicted face image based on the sweat pH, the recommended skincare product, and the second image;
- and
- presenting, by the mobile computing device, the predicted face image to the subject.
