Since this is a 100% pure essential oil, it must be diluted before applying to the skin to prevent irritation. A common guideline is to add a very small amount—just 1 to 3 drops—to a larger quantity of a suitable base product, like a tablespoon (approximately 15 ml) of a neutral face cream, lotion, or a lightweight carrier oil such as jojoba or almond oil. Always mix the oil thoroughly into your chosen base product before use. For your first try, start with the lower end of the dilution range (1 drop) and apply a small amount to a discreet area of skin, like the inside of your wrist or behind your ear, to patch test. Wait 24 hours to check for any adverse reaction before using it more widely on your face. The cooling, toning sensation it provides can help skin feel fresher and look more even by reducing the heavy, greasy feel associated with excess sebum.
