Patch Testing

How to Perform a Patch Test at Home

Before applying any homemade dilution of essential oils to larger areas of skin, it’s important to check for sensitivity or allergic reactions. A patch test is a simple way to do this safely at home.

Step 1: Prepare Your Dilution

• Always dilute essential oils with a carrier oil (such as apricot kernel, jojoba, almond, or coconut oil).

• A common starting ratio for a patch test is 1 drop of essential oil in 1 teaspoon (5 ml) of carrier oil.

Step 2: Choose a Test Area

• Use a small, discreet area of skin, such as the inside of your forearm or behind your ear.

• Make sure the skin is clean and free from other products.

Step 3: Apply the Oil

• Dab a small amount of your diluted mixture onto the test area.

• Cover it with a plaster or bandage if you like, to prevent it from rubbing off.

Step 4: Wait and Observe

• Leave the test area undisturbed for 24 hours.

• Check for signs of redness, itching, burning, or rash.

• If irritation occurs, wash the area with mild soap and water immediately and do not use the oil blend.

Step 5: Assess Results

• If no reaction occurs after 24 hours, the blend is likely safe for your skin.

• Even if the test is clear, always use essential oils sparingly and discontinue use if irritation develops later.

Important Notes

• Never apply undiluted essential oils directly to skin for patch testing.

• Avoid testing on broken, irritated, or sensitive skin.
