Choose for the real exposure
A short covered commute and hours outdoors are different use cases. Product terms such as waterproof or water-resistant should be treated as brand claims unless you have your own outcome or a suitable independent source.
- Prioritize the area most exposed to smudging.
- Avoid rubbing wet makeup.
- Bring a clean tool for a small repair.
Log what actually moved
Record the product, duration, and whether fading came from water, friction, or an unknown cause. An honest unknown is more useful than a confident guess.
Make it personal without guessing
Add an owned product and record a real outcome. MakeupCast can use that private history later without publishing it as market evidence.
