Choose a realistic check-in schedule
For most routines, a weekly photo is more useful than daily checking. Pick one day and a time you can repeat, then take an extra photo only when you introduce a product, notice irritation, or want to document a clear change.
Make each photo comparable
Use the same place, camera, distance, face angle, and lighting whenever possible. Keep filters off and use the same views each time, such as front, left side, and right side. Consistency reduces the chance that a lighting change looks like a skin change.
Add short context to every entry
A photo shows what changed, while a brief note helps explain possible context. Record routine changes, new products, dryness, breakouts, sleep, stress, travel, or cycle-related timing in a few words. Avoid trying to make a medical conclusion from one entry.
Compare trends, not a single good or bad day
Open two photos with the same view and similar lighting, then compare them weeks apart. Look for repeatable visual patterns rather than tiny day-to-day differences. Skin Progress Tracker keeps dated photos and routine notes together so you can review a longer timeline privately.
