At Corum Products we are committed to making high-performance products using the best ingredients derived from natural sources. We have carefully formulated our products to make them gentle, a pleasure to use, and good for you and your skin.
Every product you put on your skin, however, has the potential to cause irritation or an allergic reaction. It’s important to test every new product to ensure that it’s compatible with your skin or your child’s skin. By performing a patch test on a small area of the skin, you can get an idea how the skin will tolerate the product.
The patch test will take about 7-17 days.
Cleanse a section of skin for the test with a cleanser you know does not cause any irritation. Rinse and pat dry. The patch of skin should be a place on the body that will not come in contact with other products for 24 hours. Good areas to use are the bend of the elbow, behind the knees, or the belly. If you’re testing a face product, use the skin on the neck near the ear.
Apply a quarter-sized portion of the product to the area you’ve chosen for the patch test. Apply as thickly as you normally would.
If possible, over the product with a bandage or loose clothing. Leave on for as long as the instructions advise for normal use of the product. For instance, if testing a wash-off cleanser, leave it on for about 5 minutes. If testing a moisturizer, leave it on for 12 hours.
If you experience burning, itching, swelling, blistering, pain, or a rash, remove the bandage and wash the area. Do not use the product. Apply an oatmeal paste to relieve symptoms. Seek medical attention if symptoms do not improve within 3 weeks.
If you experience swelling of the lips, tongue, and throat, difficulty breathing, bleeding or oozing yellow pus, or light-headedness, seek medical attention immediately. For urgent care in the US call 1-800-222-1222.
Otherwise, wait until the time determined in Step 3 before removing the bandage or clothing. Allow redness from the bandage to fade. If the skin does not look normal, the product may not be compatible with your skin.
If the skin appears normal, repeat Steps 1-4 twice a day for 7-10 days because irritation or an allergic reaction to a product may not show up right away. If the skin appears normal after that time, it is most likely safe to use the product as directed. If you have acne-prone skin and you are testing a product for the face, start using the product on just one side of the face wherever you tend to have blemishes. Repeat for 7 days before using on the whole face.
If you regularly find yourself reacting negatively to products you put on your skin, consider asking a doctor to do a patch test to help determine which ingredients might be causing you problems.
