About Gluten - CosmeticsCosmetics

It is unlikely that you would swallow enough lip balm or lipstick to cause a problem. If you're concerned then you should contact the manufacturers directly about specific products.

It is possible to be sensitive to ingredients used in cosmetics, but this has nothing to do with coeliac disease specifically. If you experience skin irritation when using any cosmetics, discontinue use and visit your GP. 

Gum on envelopes

The Post Office and envelope manufacturers have assured us that the gum used on envelopes and stamps is gluten free and safe for people following a gluten free diet.


About Gluten - ToothpasteWe are not aware of any toothpaste that contains gluten.

Gluten only causes a problem for people with coeliac disease if it is eaten. Even if toothpaste did contain gluten, it would be very unlikely that you would swallow enough of it to cause a reaction.

If you have concerns about toothpaste, we'd recommend that you check the ingredients list and contact the manufacturers directly.
