Yuka

Yuka is a phone app that scans the barcode of a food or cosmetic product and shows a score and a breakdown of the ingredients. For cosmetics it flags ingredients according to its own risk method and can suggest alternative products. The basic app is free, with a paid version that adds features.

The score is Yuka's own judgment, built on the sources and weighting it chose, and other databases may rate the same ingredient differently. Read how it scores before you rely on it, and treat a low score as a prompt to learn more, not a verdict. People with allergies or skin conditions should go by a doctor's or dermatologist's advice.

Barcode coverage depends on the products in its database, so some items may not scan.
