What these sources establish
Manufacturer labels establish what a brand declares. Ingredient studies, supplier descriptions and public health guidance have different scopes; each explanation identifies which type supports it. A study of an ingredient does not establish the results of every serum containing it. US labels can change; always check the purchased package.
