Ferment check
Every deodorant here lists a named probiotic or postbiotic ferment on the maker's own ingredient list—not a front-label claim alone.
Each listing shows the maker's ingredient list with any probiotic or postbiotic ferment named, cites the source and the date checked, and does not treat marketing copy as an ingredient.
