Using carrier oils in aromatherapy primarily serves as a base to dilute essential oils, ensuring that they can be safely applied to the skin. Essential oils are highly concentrated and require dilution to prevent skin irritation or adverse reactions when used topically. Carrier oils, which are typically derived from the fatty portion of plants, help to moderate the potency of essential oils and allow for a safer application while also facilitating absorption into the skin.

While it is true that carrier oils can enhance the therapeutic effects when combined with essential oils, their primary and most recognized function remains as a diluent. This safety aspect is vital, as many essential oils should never be applied directly to the skin. The practice of dilution with carrier oils allows individuals to safely experience the aromatic and potential therapeutic benefits of essential oils in a way that minimizes risks.
