How to Patch Test Skincare Products
Patch testing helps people with sensitive, acne-prone, or allergy-prone skin shop more safely. This guide is general skincare education, not medical advice. If you have eczema, active acne treatment, allergies, pregnancy concerns, or persistent irritation, ask a qualified doctor.
Choose a small area
Apply a tiny amount behind the ear or along the jaw.
Wait 24 hours
Watch for redness, burning, itching, swelling, or rash before using it on the full face.
Stop if irritated
Do not continue a product that causes persistent discomfort.
