How to actually read an ingredient label
Position on the list matters more than the name. Here's the five-second method.
Ingredient lists are ordered by concentration, highest to lowest — which means the first five ingredients usually make up over 80% of what's in the bottle.
If a hero ingredient like niacinamide or vitamin C is buried near the bottom of a long list, it's likely there at a dose too low to do the job the marketing promises. Position is the tell.
Water, glycerin, and a handful of emollients will almost always lead the list — that's normal and not a red flag. What matters is where the actives you're paying for actually land.
A five-second read: find the active you care about, count how many ingredients come before it. Under ten is a good sign. Past twenty, temper your expectations.
