What is a Skin Patch Test?

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.   

Allergic Reaction



Why Should I Do a Patch Test?

Patch tests are very important because they help you avoid possible adverse reactions to new ingredients or products. They are helpful for people who have allergies or very sensitive skin.


Performing an Allergy Patch Test

Be sure the area of skin on which you will be performing the test is clean and dry.

  • 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.)

safety first

What is a Patch Test 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.


Scented natural soaps have 100% pure plant essential oils added and plant based fragrance, not synthetic fragrances. "All-natural" does not mean "allergy-free." Natural plant essential oils and plant based fragrances may still cause skin irritation or reactions in certain individuals. If you develop 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 preparation area is kept meticulously clean and all soaps are cured in a dedicated area. There may be times when one soap may touch another and we cannot guarantee that soaps always remain separated.
