How To Do A Simple Allergy Patch Test
What is Skin Patch Testing?
Patch testing is a method of testing a new skincare product or a new skincare ingredient to see if it will work for your unique skin. A lot of skin problems are caused by using ingredients that cause sensitivities for your skin.
If you have sensitive or allergic skin, it’s always recommended to do a patch test. Even natural ingredients, like herbs, oils, or essential oils can cause sensitivity reactions.
Please note that although patch testing may help to identify a problem ingredient, it is not always a foolproof test. A patch test is not a guarantee against a skin sensitization in the future.
Why Are Patch Tests Needed?
Patch tests are very important because they help you avoid possible adverse reactions to new ingredients or products. They are especially helpful for people who have allergies or very sensitive skin.
Allergy Patch Test
- Be sure the area of skin on which you will be performing the test is washed, dry and clean.
- Apply a small amount of item you are testing* on the upper part of your inner arm (at the crook of the elbow).
- Cover it with a bandage.
- Choose a time of day where you can leave the patch test in place for at least 24 hours without getting it wet.
- If you are sensitive to any of the ingredients, a reaction such as reddening, burning, itching, or other irritation, should occur within twenty-four hours of application.
- If you feel any irritation or reaction, remove the bandage immediately and wash the area with soap and water.
- If you don't see or feel any reaction, the preparation is probably safe to use. (See note below under Allergic contact dermatitis.)
*If you are testing herbs, mix a small amount of herbs with water to make a paste. Apply the herbal paste for the patch test.
What is Patch Testing Looking For?
Patch testing is a way of identifying a substance that causes contact dermatitis (inflammation of the skin). There are two types of contact dermatitis: irritant contact dermatitis and allergic contact dermatitis.
Irritant contact dermatitis: An irritant reaction does not involve the immune system. It is most pronounced immediately after the patch is removed and fades over the next day. Although a substance that causes an irritant reaction may exacerbate skin conditions such as eczema, the reaction will not get worse with repeated exposure to the irritant.
Allergic contact dermatitis: An allergic reaction is due to a substance called an allergen and occurs only in those who are allergic to that particular substance. These reactions involve the immune system.
Note: Since an allergic reaction may take a few days to develop if you are an allergic-type person it is important to keep an eye on the patch area for a few days after the patch is removed before using the product. A substance that causes an allergic reaction should be avoided completely. The more times the skin is exposed to the substance, the worse the allergic reaction can become.
Some of our natural soaps have no scent added—you’ll love the earthy smell of natural soap. Many have distinct natural aromas due to honey, grains, flowers, spices, or herbs.
Scented natural soaps have all pure plant essential oils added, not synthetic fragrances. Again "all-natural" does not mean "allergy-free." Natural plant essential oils may still cause skin irritation or reactions in certain individuals.
If you notice any adverse effects, please discontinue use.
People with severe allergies--please note: If you have severe anaphylactic type reactions to ANY of the ingredients we use please do not buy our products. Our soap shop is kept meticulously clean and all soaps/shampoos are cured in separate containers. But we cannot guarantee that one soap did not touch another.
