There are numerous products and ingredients that we use daily that can lead to rashes and discomfort. These include sensitivities that may be a result of allergy or toxicity. The most common allergy to chemicals is a contact dermatitis. This type of allergy manifests similarly to poison ivy. In addition to a detailed history, Dr. Chahine has appropriate testing options that can identify the offending agent. The tests include comprehensive allergen patches and direct tests with the products as well.
