Well, it’s definitely more than just ‘water in a bottle’. Micellar cleanser is fantastic for those with more sensitive skin and dry skin - here’s why.
Cleansing water contains super low amounts of surfactants - aka, the ingredients that make your regular cleanser foam up. This makes micellar cleansing water actually able to grab any oil and water-based grime from the skin without stripping the skin.
These surfactants form unique shapes called ‘micelles’ - hence the name micellar water. Micellar waters aren’t as good at removing heavy-duty, waterproof mascara compared to cleansing oils - they’re better suited for light makeup removal.
In any case, you should be following up your preferred makeup removal step with a regular cleanser - a process that’s called double-cleansing.
