A patch test is a small step that takes a minute and can save you from a bad surprise. We suggest it for any new product.
How to do it
- Wash and dry a small area of skin, such as the inside of your forearm.
- Apply a small amount of the product.
- Wait and watch how your skin feels over the next day.
Why it matters
Skin is personal. A product that suits one person may not suit another, and a quick test shows how your skin responds before you use it on your face.
One product at a time
If you add several new products at once, you cannot tell which one caused a reaction. Introduce them one by one, a few days apart.
