Patch tests are an easy way to help predict if you may experience a negative initial reaction to a new product. It is recommended to perform a patch test before incorporating any new product into your regimen. We have outlined a general method for conducting your own patch test below based on the type of product.
- Apply a small amount of the product onto a clean area of skin on the upper forearm.
- Keep the area dry.
- If the product has a specified duration of use, rinse off after this time has elapsed. Otherwise rinse off after 24 hours.
- If any redness, burning, itching, blistering or irritation is observed at any time throughout the test, do not use the product.
