Question about a rating?
Tell us the ingredient, the rating you think is wrong, and the source. We check reports against the source, and fix what we got wrong.
Know a source we should add?
Send a link to the study or list. We add studies once we can read the full text, and lists only when their terms or their owner allow it. See the sources we use now →
Ingredient not found?
Send the name exactly as it's printed on the label. If a source rates it under another name, we'll add that name so the checker finds it.
We can't give medical advice. If your acne is painful, leaves marks, or doesn't get better, see a doctor or a dermatologist.
