Patch testing is a way to check if a new skincare product is safe for you to use. It's a simple process that involves applying a small amount of the product to a small area of skin and waiting to see if there's any reaction.
To patch test a skincare product, start by choosing a small, inconspicuous area of skin, such as the inside of your wrist or behind your ear. Clean the area with gentle soap and water and let it dry completely. Then, apply a small amount of the product to the area and wait for 24 hours.
During this time, avoid touching or washing the area, as this could affect the results of the test. If you experience any itching, redness, swelling, or other signs of irritation, wash the area immediately with water and discontinue use of the product.
If there's no reaction after 24 hours, the product is likely safe for you to use. However, it's still a good idea to introduce new skincare products slowly and one at a time, so that you can be sure that your skin can tolerate them. If you do experience any irritation or other reactions in the future, stop using the product immediately and seek medical advice if necessary.
