The catalogue

Skincare ingredients, checked against six profiles.

Every other ingredient checker answers one question: is this generally fine, for anyone. This one answers six. Given that you are pregnant, or breastfeeding, or managing PCOS, or just asking in general, is this particular ingredient a problem for you now.

Ingredients

1,202

Flagged in at least one profile, or named often enough by the flagged ones to be worth its own page.

Profiles

Pregnancy, breastfeeding, postpartum, trying to conceive, PCOS and general use.

Assessments

7,212

One per ingredient per profile, each with its own level and evidence rating.

Catalogue read 15 September 2026. Every figure on this page comes out of that snapshot.

Most common

The 12 you will meet most often.

Ordered by how often they turn up on a label, not by how alarming they sound. The number on each card is its place in that order. What the catalogue makes of an ingredient is on the ingredient's own page, where the evidence behind it is.

By profile

Start from where you are.

The same ingredient sits in one of these lists and not in another, which is the point. Read the five figures across: one catalogue, five profiles, and nothing like the same answer.

A to Z

Every ingredient in the catalogue, on one page.

All 1,202 of them, so no ingredient page is reachable only from the sitemap. Names only here. Open one to see which of the six profiles it is flagged in, at what level, and on how much published evidence.

The short way

Reading a label is slower than pointing a camera at it.

This index is the long way round, and it is here because it should be. Truva is the short way: scan the back of the bottle and get one answer for the profile you are actually in, with every flag naming the ingredient it came from.
