How to Perform a Patch Test
A patch test is an effective method for determining potential skin reactions to new products, including cosmetics, cleansers, emollients, and topical medications.
1. Use a Small Area of Skin
Prior to utilizing a new product, select a small area for a patch test, ensuring it remains undisturbed for up to 24 hours. Typical sites include the inner arm or side of the neck.
2. Patch Test Preparation
Select an area for the patch test and thoroughly cleanse the skin. Maintaining cleanliness in this region is crucial to guarantee the accuracy of the test results. In case of a reaction, it is essential to ascertain that it originates from the new product and not an external factor.
3. Apply and Wait 24 Hours
Apply a small amount of the new product onto the area and cover with a bandage. Wait at least 24 hours before removing the bandage. If you experience any burning, itching, or pain, remove the bandage and wash the area immediately.
4. Observe Your Skin
After waiting 24 hours, remove the bandage and observe your skin. If it appears red, bumpy, raised, or itchy, then it is likely that you have an allergy to an ingredient in the product and should discontinue use. If you are unsure about the results from the patch test or have previously experienced allergic reactions to skincare products, we recommend asking your doctor to perform an allergy test to determine which specific ingredients you may be allergic to.
