Arm pit rash: The key to allergic contact dermatitis reactions such as those with deodorants is location. A rash limited to the area of contact is suggestive of a reaction to an ingredient in the product. An allergist or dermatologist can provide allergy patch testing to attempt to identify the specific chemical.

Try application of the deodorant to another area. Observe if the same reaction takes place.
