Ingredient lists on skincare and haircare products are ordered by concentration, highest first, under Indian labelling rules (and most others worldwide). Anything below about the 1% mark can appear in almost any order, which is why you’ll often see a long tail of similar-sounding names bunched at the end — that’s not a trick, it’s just how the rule works once concentration drops low enough that order stops being meaningful.
A few reliable landmarks to look for:
- Water (Aqua) is usually first in anything that isn’t an oil or balm — it’s the base most formulas are built on.
- Glycerin and hyaluronic acid are humectants: they pull moisture in rather than sealing it. Look for them anywhere in the first half of a moisturiser’s list.
- Fragrance (Parfum) can be a single umbrella term hiding dozens of individual compounds. If you have sensitive skin, this is the word to scan for first, not further down the list.
- Preservatives — things like phenoxyethanol, sodium benzoate, or the various parabens — are normal and, at the concentrations regulators allow, are there to stop the product growing mould in your bathroom, not to harm you.
What the list won’t tell you is concentration in percentage terms (except for a handful of actives that brands sometimes choose to disclose), and it won’t tell you whether an ingredient was included at a level high enough to actually do anything. A “vitamin C serum” with ascorbic acid buried near the preservatives isn’t doing much vitamin-C work, regardless of what the front of the bottle claims.
The most useful habit is comparing two products in the same category side by side. You don’t need to memorise INCI names — you just need to notice where your problem ingredient sits, and whether the actives you’re paying for appear early enough in the list to matter.
