No, avocado is not an essential oil, but it can be used as a carrier oil. Essential oils are highly concentrated, fragrant and volatile, and they are extracted from the flowers, leaves or seeds of aromatic plants. They usually need to be diluted before being applied to the skin, as their high concentration can cause irritation. Carrier oils, on the other hand, are extracted from the fatty parts of plants, such as the fruit pulp, seeds or nuts. They are not volatile, don’t normally irritate the skin and have a more subtle smell, so they can be used to dilute essential oils for safer application.
