With proper care of the rash and avoidance of the irritating substance, most cases of underarm redness resolve in two to three weeks. Sometimes the rash is severe, and corticosteroid pills or injections are required, states MedlinePlus. Certain chemicals found in deodorant are commonly responsible for producing skin reactions, including fragrance, propylene glycol, parabens, vitamin E and lanolin, states About.com. Trying a hypoallergenic deodorant formula is recommended for individuals who are sensitive to any of these ingredients.
If individuals experience recurrent or long-term underarm redness, allergy testing with skin patches is typically recommended to determine the allergen that is responsible, explains MedlinePlus. This process requires three appointments with an allergist, who applies patches to the skin that contain possible irritants. The patches are removed after 48 hours to check for a reaction, which indicates an allergy to that substance. Another visit is scheduled about two days after the patches are removed to check for delayed reactions.Learn more about Skin Conditions
