Skin Allergy Patch Testing

Skin Allergy Patch Testing

Skin allergy patch testing involves applying small patches with potential allergens to your skin, typically the back, for 48 hours to identify substances causing contact dermatitis. After removal, the skin is examined for redness or itching at specific sites, which indicates a reaction. Treatment for confirmed allergies involves avoiding the identified allergens, such as those found in certain cosmetics, metals, or chemicals, and managing skin symptoms with corticosteroids if necessary.
