Image-based measurement and its limits · diagnostic claims and what software is cleared to say · skin assessment by examination
Dr. Ke He is Deputy Director of the Plastic Surgery & Aesthetics Medical Center at Chongqing West District Hospital and head of its skin and laser aesthetic service — and she is the lead physician of this site. A core specialist formerly at the Plastic and Aesthetic Surgery Department of Xinqiao Hospital, affiliated with Army Medical University, she has worked on the clinical front line in skin laser and injectable aesthetics for more than 20 years, serving over ten thousand patients.
On this review his part is the difference between a measurement and a diagnosis. He treats software output as a number that has to be interpreted rather than as a finding, and he asks what a model was trained on before he trusts what it says about anyone’s skin. Where a tool is cleared to measure and a marketing sentence implies that it diagnoses, he names the gap rather than working around it. Where a lesion needs to be looked at he examines it, because no photograph and no algorithm is cleared to make that call, and where a person arrives with a score they have been shown elsewhere he starts again from what they can see and feel rather than from the number.

A measurement is not a diagnosis
A number can be produced reliably and still be asked to mean more than it can carry. Describing an image and naming a disease are two different regulatory acts, and the second one requires evidence the first does not — which is why the sentence on a website and the clearance behind the product are worth reading separately.
