Overview
Toners and essences are watery liquids applied a little at a time — usually shaken onto a cotton pad or into the palm — so their bottle needs to release product in a controlled trickle rather than a gush. A reducer or sprinkler plug in the neck does this, metering the flow so the user gets just a splash.
The slim, tall silhouette suits multi-step Korean and Japanese skincare routines, where a toner sits among several elegant bottles on the shelf.
