Patch testing is an important way to ensure that a new product, such as essential oils or cosmetics, will not cause allergic reactions on the skin. Here's how to properly perform a patch test and what to consider.

Materials

  • The product to be tested (e.g. essential oil, bath oil)
  • A carrier oil (e.g. almond oil, jojoba oil)
  • Patch or bandage

Instructions

  1. Prepare the product : Dilute the essential oil with a carrier oil. A common mix is ​​1-2 drops of essential oil per 1 teaspoon of carrier oil.

  2. Apply : Apply a small amount of the diluted mixture to an inconspicuous part of the skin, such as the inside of the forearm.

  3. Cover : Cover the area with a plaster or bandage to observe the reaction.

  4. Observe : Leave the test on the skin for at least 24 hours (ideally 48 hours) and observe the reaction.

Assessment

  • No reaction : If no redness, itching, or swelling occurs, the product is probably safe for your skin.
  • Reaction : If redness, itching, swelling or blisters appear, remove the product immediately and rinse the area with water. Do not use the product further.

Important questions

  1. How to dilute essential oils for a patch test? Use a carrier oil and mix 1-2 drops of essential oil per 1 teaspoon of carrier oil.

  2. Where to do the Patch Test? The inside of the forearm is ideal because the skin is sensitive and reactions are clearly visible.

  3. How long should you observe the Patch Test? At least 24 hours, ideally 48 hours, to ensure that no delayed reactions occur.

Conclusion

Patch testing is a simple but crucial way to avoid skin reactions to new products. Follow these instructions carefully to ensure your skin stays safe and healthy.
