PCOS
Skincare ingredients to watch with PCOS
PCOS is not a pregnancy profile and its list looks different because of it. 308 ingredients are flagged, and the concerns behind them cluster around hormones rather than development: compounds that mimic androgens, disturb insulin, or push an already reactive skin further.
Flagged means avoid, high risk or medium risk. Almost nothing here is dangerous in the way a teratogen is dangerous. The question a PCOS flag answers is whether an ingredient is likely to make acne, unwanted hair growth, or the hormonal picture behind them worse. Every ingredient below has its own page with the level, the evidence behind it and the safer options the catalogue names. The full index is at all ingredients, A to Z.

The same ingredient, answered four other ways.
An ingredient is not safe or unsafe on its own. It is safe or unsafe for a person at a point in their life, which is why the same name sits in one list and not in another.
The short way
Skincare that knows PCOS is not a pregnancy.
Truva keeps PCOS as its own profile, so a product that is fine for pregnancy and wrong for you does not come back clear.
