How to Patch Test a New Bath and Body Product

Trying a new bath or body product should be an enjoyable experience. However, because everyone’s skin is different, even a thoughtfully formulated product may not agree with every person.

Performing a simple use test on a small area of skin before applying a new product more broadly can help you see how your skin responds.

What Is a Patch Test?

The phrase “patch test” is often used casually to describe trying a small amount of a new product on a limited area of skin before using it as usual.

This type of at-home test may help you notice signs of irritation or sensitivity, such as redness, itching, burning, swelling, or a rash. However, it cannot guarantee that you will never experience a reaction, and it is not the same as the diagnostic patch testing performed by a dermatologist.

Why Should You Test a New Product?

Every person’s skin is unique. A product that works beautifully for one customer may not be suitable for another, particularly when fragrance, essential oils, botanical ingredients, preservatives, or known allergens are involved.

Testing one new product at a time makes it easier to recognize which product may be causing a problem if irritation develops.

A use test is especially worth considering if you:

• Have sensitive or reactive skin

• Have experienced reactions to skincare products in the past

• Are trying a new fragrance or ingredient

• Have known skin allergies

• Plan to use the product over a large area

How to Test a Leave-On Product

Leave-on products include lotions, body butters, perfume oils, fragrance mists, and similar products that remain on the skin.

1. Choose a test area. Select a small, discreet area of healthy skin, such as the underside of your forearm or the bend of your elbow. Do not apply the product to broken, freshly shaved, sunburned, or already irritated skin.

2. Apply a small amount. Use approximately the same amount and in the same way you would during normal use.

3. Repeat the test. Apply the product to the same area twice daily for seven to ten days, unless the product directions say otherwise.

4. Watch for a reaction. Check the area for redness, itching, burning, swelling, tenderness, bumps, or a rash.

5. Stop if irritation occurs. Gently wash the product from your skin and discontinue use if you notice discomfort or a reaction.

How to Test a Rinse-Off Product

Rinse-off products include soap, whipped soap, body wash, and body polish.

Apply the product to a small area of healthy skin and use it just as you normally would. For example, lather soap on the test area, leave it in contact with your skin only for the usual amount of time, and then rinse thoroughly.

Do not leave a rinse-off product on your skin for hours in an attempt to test it. That would not reflect normal use and could cause irritation.

Repeat the test on the same area over several days while watching for redness, itching, burning, dryness, swelling, or a rash.

What Should You Do if Your Skin Reacts?

If you notice irritation, stop using the product and rinse the area thoroughly. Avoid applying the product again, even if the initial reaction seems mild.

Contact a healthcare professional if the reaction is significant, does not improve, or you are unsure how to care for it. Seek urgent medical attention for symptoms such as difficulty breathing or swelling of the face, lips, tongue, or throat.

When an At-Home Test Is Not Enough

A home use test may help you see whether your skin appears to tolerate one particular product, but it cannot diagnose an allergy or identify the ingredient responsible for a reaction.

If you have recurring rashes, eczema, known contact allergies, or a history of serious reactions, speak with a dermatologist or other qualified healthcare professional before trying new products. A dermatologist can perform formal patch testing when appropriate.

A Note for Customers with Allergies

Please review the complete ingredient list before purchasing or using any Hickory Ridge Soaps product. If you have a known allergy to an ingredient listed in a product, please do not use that product.

Our products are made and packaged in shared work areas. Although we follow careful cleaning practices, we cannot guarantee that a product will be completely free from trace cross-contact with other ingredients used in our workspace.

A Thoughtful First Step

Taking a little extra time to test a new product can help you introduce it to your routine more carefully. Once the testing period is complete and your skin shows no signs of irritation, you can begin using the product as directed.

Remember that reactions can still develop later, so discontinue use if irritation occurs at any time.
