Patch Testing lasts for a specific period, usually 48 hours, during which your skin is exposed to potential allergens. After this period, your provider will remove the patches and examine your skin for reactions, which can include redness or inflammation. These results help identify the allergens responsible for skin allergies and inform personalized treatment plans for effective management.
During Patch Testing, your skin may be exposed to several types of substances that can cause dermatitis, including but not limited to nickel, fragrances, and preservatives.
During a Patch Test, your provider will advise you to limit certain activities that will cause your patches to move or cause you to sweat such as bathing or exercising.
