Are there any safety precautions I should be aware of when using tea tree essential oil?

Tea tree essential oil is highly concentrated, so it must be used with attention to dilution and skin sensitivity. Before broader use, always perform a patch test by applying a diluted amount (mixed with a carrier oil or cosmetic base) to a small area of skin and waiting 24 hours to monitor for any redness or irritation. Avoid contact with eyes and mucous membranes. If your skin is very reactive, or if you are pregnant, breastfeeding, or planning to use it on a child, it is sensible to consult a qualified specialist before incorporating it into your routine. Store the oil in a cool, dark place away from direct sunlight to preserve its quality. This product is for topical cosmetic use only and is not intended to diagnose, treat, or prevent any disease.
