How to patch test a new cream, and why we ask you to

Skin that reacts easily can react to almost anything, including ingredients that are mild for most people. Botanical extracts, emulsifiers, and preservatives are the usual suspects, and every cream has some of each. AuraAnn Mineral Cream lists lavender and chamomile extracts, phenoxyethanol, and ethylhexylglycerin, all of which are common in gentle products and all of which a small number of people do not get along with.

A patch test does not tell you the cream will work for you. It tells you whether your skin tolerates it, which is the first question worth answering.

It takes less than a minute a day.

• Pick a spot you can see but do not scratch: the inner forearm or behind the ear.
• Apply a thin layer to a coin-sized area. Do not cover it.
• Repeat once a day for two days on the same spot.
• Check each morning for redness, raised bumps, itching, or stinging that lasts.
• If the skin looks and feels normal after two days, use the cream as directed.

Mild, brief tingling on very dry skin can happen with many moisturizers and usually passes in a minute or two. Redness that spreads, itching that builds, or a rash that appears within a day are different. Wash the area with cool water, stop using the product, and give the skin a few days. If it worsens or does not settle, see a doctor.

If you have a known allergy to oats, lavender, chamomile, or any listed ingredient, do not use the cream. The full ingredient list is on the jar and on the product page.

The same method works, and it matters more, because a child cannot always tell you what they feel. Ask your pediatrician before using any new product on a child under two or on broken skin.
