The reason is that certain ingredients can irritate the mucous membranes lining the mouth, nose, and throat.
This causes an allergic reaction called hypersensitivity.
If you have this reaction, your doctor can prescribe an antihistamine or a nasal spray to ease symptoms.
However, if you are allergic to any other ingredients, the only option is to stop using the product and wait for it to dry.
That’s not going to happen if you can’t get a hold of a mask, because it’s not yet available in Canada.
If your allergy is not clear, contact your doctor to find out how to get an allergy test.
You can also contact the Food and Drug Administration in the United States to learn more about the ingredients in cosmetics.
