HOW TO READ IT

What it means in the INCI list?

In the European Union, ingredients above 1% are listed in descending order by weight; below 1%, they may appear in any order. Their position therefore cannot be used to calculate an exact percentage.

Its position helps you understand the formula, but does not on its own establish effectiveness or an exact percentage.
