How to patch test a new product
A patch test at home is no guarantee, but it can catch a reaction before it spreads to your whole face.
- Apply a little of the product to a small area, such as behind the ear or along the jawline.
- Do it morning and evening for five to seven days, in the same spot.
- If it turns red, itches, stings or gets bumpy – stop, and don't use the product on your face.
- No reaction? Start using it on your whole face, but wait a couple of weeks before trying the next new product.
