A patch test is a specialized skin allergy test used to identify substances that cause delayed allergic reactions. Unlike other allergy tests, it focuses on contact-based allergens—things your skin touches daily like cosmetics, metals, or chemicals.

This test is especially helpful for diagnosing:

• Allergic contact dermatitis
• Cosmetic allergies
• Skincare product reactions
• Occupational skin allergies

How Does a Patch Test Work?

The patch testing process is simple but highly effective:

1. Small amounts of allergens are applied to patches
2. Patches are placed on your back
3. You wear them for 48 hours
4. Your allergist checks reactions over several days

This method helps identify delayed reactions that don’t appear immediately.
