Hi Robert! Most ingredients derived from grain sources are highly refined and retain no traces of gluten proteins. For less refined ingredients from natural sources, Maybelline has established strict limits on the level of potentially allergenic proteins. Since individuals exhibit a wide range of sensitivities to these proteins, if you have any questions or concerns you should discuss with your medical care provider. All the ingredients we use in a product are listed on the package or the label of the product itself. For products too small to accommodate the list, a separate ingredient list is available on the display unit in the store for your convenience. Since some ingredients are known by more than one name, we use the standard industry FDA-recognized names. A review of the ingredients that are listed on all of our products or packages will alert you to the presence of this type of ingredient.
