Most people never see a dermatologist. They manage their skin alone, with whatever they can piece together from the mirror, the internet, and something they were told once by someone at a counter.
For the ones who do come in, I get fifteen minutes, maybe twice a year. And I'm trying to understand six months of skin from memory, theirs and nothing else. When did it start? Was it gradual? What was going on that month? People do their best. But nobody can reliably recall the state of their own face in March.
Whether or not you ever sit in front of someone like me, the same thing is missing. Not expertise. A record.
Most changes happen between appointments. Without a continuous record, they're easy to forget, impossible to compare, and difficult to explain. That's where tracking changes everything.
Why you can't just remember it
This isn't a failure of attention. Skin changes slowly, and slow change is the hardest kind to perceive: you're comparing against this morning's mirror, not against February. By the time something is noticeable enough to mention, it's usually been underway for a while.
The people who track it are better off. But most tracking means photos in a camera roll, taken in different light, at different distances, at unpredictable intervals. It's better than nothing. It's not a record.
Why asking an AI doesn't close it either
A lot of people now describe their skin to a chatbot and get a fluent, confident, sensible-sounding answer back.
The answers aren't stupid. They're just about skin in general, because that's the only thing the model has. It doesn't know what your readings were doing in April. It has no access to the interval, so it fills the gap with population averages and delivers them in the second person.
It's a context problem, not an intelligence problem. You cannot analyse a record that was never kept.
