How to patch test a new product
A few days of care that can save your skin.
1 minute to read
Where to test
Apply a small amount behind the ear or along the jawline, where the skin is similar to your face but less visible.
How long to wait
Use it once a day on the same spot for three to five days. Redness, itching or bumps mean it isn't right for you. No reaction means you can introduce it slowly.
Introduce one new product at a time, so you know what your skin is reacting to.
