How to Patch Test a New Skincare Product

Published 20 Oct 2026

A patch test means trying a small amount of a new product on a small area of skin before using it more widely. It takes two minutes to do and can help you notice a reaction early. Do it for every new cream, serum, face wash, peel or lotion, even if the pack says it is suitable for all skin types.

Why a patch test matters

Any product can bother some people, including products made from ingredients that sound gentle. Fragrance, essential oils, acids and preservatives are common reasons for irritation. A patch test does not guarantee that a product will suit you, but it helps you catch an obvious reaction on a small spot instead of on your whole face.

How to patch test, step by step

1. Wash and dry your hands and the test area.
2. Choose a small spot. The inner forearm, the skin behind the ear or the side of the neck are common choices.
3. Apply a small amount of the product, about the size of a grain of rice.
4. Leave it on, unless the pack says to wash it off after a set time. Do not cover it.
5. Check the spot after 24 hours and again after 48 hours.
6. If there is no redness, itching, swelling, burning or rash, you can start using the product, beginning with a small amount.

Signs you should stop

• Redness, itching or a burning or stinging feeling that does not settle
• Swelling, bumps or a rash
• Watery or sore skin

If any of this happens, wash the area with plain water and stop using the product. If the reaction is strong or does not go away, speak to a doctor.

Extra care for strong products

Peels, acid serums and exfoliating products need more care. Follow the time on the pack, never leave them on for longer than directed and avoid using several strong products on the same day. Our guide on using face peels at home safely explains this in detail.

Eye-area products

The skin around the eyes is thin and sensitive. Do a patch test on your forearm first, then apply only around the orbital bone and keep the product away from the eyes. Rinse with clean water if it gets in your eyes.

Good habits after a patch test

• Introduce one new product at a time.
• Keep products away from heat and sunlight, and close the lid after use.
• Check the manufacturing and expiry details on the pack before using a product.
• Do not use a product on broken, sunburnt or irritated skin.
