How Truva compares to the other scanners.
Yuka, Think Dirty and EWG Skin Deep all answer the same question: how does this product rate, in general, for anyone. Truva answers six, one for each profile. Given that you are pregnant, or breastfeeding, or managing PCOS, or just asking in general, is this particular product a problem for you.
Each page below says where the other app is the better choice, and links every figure to the page that app publishes it on. If you would rather see the whole category at once, the ranked roundup of pregnancy safe skincare apps covers seven of them, Truva included, on the same rule.
Truva and Yuka
Yuka scores a product once, for everyone. Truva reads the same label six ways, one for each life stage, and names the body behind every flag. An honest comparison.

Read the comparisonThe difference in one sentence
A scanner that does not know your situation has to compute one score from the product alone. Truva asks first, then reads the label against published guidance for the 6 profiles it covers: Pregnancy, Breastfeeding, Postpartum, Trying to Conceive, PCOS and General Use.
That is why the same retinol serum can come back Safe to Use, Caution Advised and Not Recommended from one app. It is not inconsistency. It is three different people asking. Our post on glycolic acid and salicylic acid works one of those splits through in full, with the page each body published it on.
Two of the six carry the least published guidance of any of them, and they are the two a scanner with no profile cannot ask about at all: trying to conceive, where the question is usually about timing rather than about the ingredient, and postpartum, where an instruction written for pregnancy may or may not still apply. The catalogue lists what is flagged in each, with the reason and the body named on every entry. Retinol is the clearest single case: Not Recommended in pregnancy, while breastfeeding and while trying to conceive, and Safe to Use once you are postpartum and not breastfeeding.
Truva summarises published ingredient guidance from ACOG, the FDA, the EU SCCS and the Cosmetic Ingredient Review. It has no access to your medical history and it is not a substitute for your doctor or midwife. Truva is free to scan; Truva Pro is $29.99 once.
