How do I patch test a new skincare product?
Patch testing at home is a cautious screening step, not a medical allergy test. Use a small area that is not already irritated, apply the product as directed, and observe immediate and delayed changes over the next few days.
A negative small-area test cannot guarantee that the face will tolerate the product, especially around the eyes. If you have repeated reactions or need formal evaluation, ask a clinician about dermatology assessment or patch testing.
