Perform a patch test before applying lavender oil to any new areas. Use diluted oil and apply it to a small area behind one of your ears. Apply a bandage and wait 24 hours before assessing for redness, itching, or swelling. I require this from all new clients. It minimizes the risk of a widespread reaction due to sensitivities that you might not be aware of.

Appropriate storage practices preserve oil safety and effectiveness. Lavender oil should be stored in dark glass bottles to prevent exposure to sunlight. Store faintly used in rooms cooler than 70°F (21°C). Dispose of oils older than 18 months. Avoid using oils that smell foul or have discolored. These tips help avoid deterioration that increases skin irritation risks.

Learn when to seek professional help for adverse reactions. Poison control should be contacted if children consume any amount. For severe and extensive skin reactions, consult a physician. Consult a physician immediately if you experience respiratory distress after inhaling any substance. Always take the oil bottle to all medical appointments. This will help ensure professional treatment for the specific exposure.
