You should avoid the following types of products if they contain gluten, because some might accidentally get into your mouth and be swallowed:
In all cases, if you don’t know whether a product contains gluten, check the ingredient list, visit the website, or call the manufacturer.
The same is true for people with dermatitis herpetiformis. This painful skin disorder, which causes an itchy, blistering rash, results from eating gluten, not from skin contact with gluten.
If you develop a skin reaction to a cosmetic or skin-care product that contains gluten, you may be having an allergic reaction to one or more of the ingredients. Your doctor or a dermatologist can help you identify the offending ingredient(s).
