A quiet, private record of how your skin looks over time.
Take the same kind of selfie you always take. Lumen Journal saves it privately, gives you a cautious, plain-language note on visible changes since your last photo, and keeps a dated timeline that only you can see.
Private by design
Every photo and note belongs to your account alone. No sharing, no public feed.
Visible, not diagnostic
Notes describe brightness, tone, and lighting changes you can see — never a diagnosis or an internal health reading.
A dated timeline
Revisit any past entry, with the date and device it was taken on, whenever you want.
Before you start
Lumen Journal is a personal wellness journal, not a medical device. It does not diagnose any disease and cannot assess internal health conditions, including kidney function, from a photo. If you notice a change that concerns you, please talk to a licensed clinician.
