What's actually free?
The entire checker. Paste any ingredient list and every recognised ingredient is scored on the 0–5 comedogenic scale, sorted highest-first, and explained. You see the rating, what it means for congestion-prone skin, and a lower-rated alternative where one exists. Nothing about the result is locked behind a payment or an email.
Why "free comedogenic checker" usually disappoints — and what's different
Many tools that target this search only recognise a short buzzword list or hide the full breakdown behind a signup. This one is built on 185 ingredients with cited comedogenic ratings, and the complete rating table appears instantly. Your ingredient list never leaves the browser, so checking a product you are about to buy stays entirely private.
Good places to start
- The 0–5 comedogenic scale explained, score by score.
- Comedogenic ratings for every ingredient in the database.
- The non-comedogenic checker to confirm a product stays in the 0–2 range.
