This feature can be used with either a photo taken on the spot or a photo saved in your photo library. To
use this feature, open the "Facial Analysis AI" from the dashboard items, press the "Start Diagnosis withCamera" button to begin the apparent age diagnosis. If taking a photo on the spot, face the camera directly
and ensure your face fits within the frame.
When diagnosing from a saved photo, it is recommended to use a photo that is facing forward and has
been cropped to only include the face. The analysis by AI is performed immediately, and the results aredisplayed shortly after. The apparent age is shown as a range, like "X to Y years old." The diagnosis results
are recorded, and history can be reviewed, allowing users to see changes from past results. You can use
this as a health indicator by comparing it with your actual age or previous diagnosis results.
