What is the significance of using a carrier oil with essential oils?

Using a carrier oil with essential oils is significant because it dilutes the essential oil for safe application. Essential oils are highly concentrated extracts and, when used in their pure form, can lead to skin irritation or sensitization. By mixing them with a carrier oil, these concentrated oils are safely blended, allowing for a more controlled application that reduces the risk of adverse reactions. This dilution is essential for topical use, as it allows the user to benefit from the therapeutic properties of the essential oils without compromising skin health.

While enhancing aroma, increasing viscosity, or providing a cooling effect are factors that may come into play with certain oils, they do not encompass the primary reason for using a carrier oil in aromatherapy. The main focus is always safety and efficacy in the application of essential oils.
