How to Patch-Test a New Product

Patch-testing is a simple habit that can save you from an uncomfortable reaction across your whole face. It is especially worth doing if you have sensitive skin, known allergies, or are trying an unfamiliar product or ingredient.

Why patch-test

Even products marketed as gentle can cause a reaction in some people. Testing a small area first gives your skin a chance to respond before you commit to applying something more broadly. It is a small step that lowers the chance of an unpleasant surprise.

A simple approach

Choose a discreet spot. A small area such as the inner forearm, or just along the jawline near the ear, is commonly used. The jaw area can be useful because the skin there is closer to facial skin.

Apply a small amount. Use a little of the product on that spot, following how the product is meant to be used.

Wait and watch. Give it time, often a day or two, and repeat over a few days if you want to be thorough. Watch for redness, itching, stinging, swelling, or bumps.

Stop if you react. If you notice irritation or any reaction, wash the area, stop using the product, and give your skin time to recover. If a reaction is severe or does not settle, seek medical advice.

A note on ingredients

If you have a known allergy, patch-testing does not replace reading the full ingredient list. Product information from any source, including ours, can be incomplete or out of date, so checking the actual label on the product is always the reliable step.
