Patch testing helps identify whether your skin condition is caused or made worse by an allergic reaction to certain substances.
During the test, small amounts of potential allergens are applied to your back using adhesive patches. These stay in place for a couple of days before being carefully checked by your dermatologist to see how your skin reacts.
Patch testing is a safe and effective way to find the cause of allergic skin reactions and guide your treatment or prevention plan. Your dermatologist will explain the process, what to expect, and how to care for your skin during the testing period.
