What is the purpose of carrier oils in aromatherapy?

The purpose of carrier oils in aromatherapy is primarily to dilute essential oils for safe skin application and to provide moisture. Essential oils are highly concentrated and can potentially cause skin irritation if used directly. Carrier oils are used to minimize this risk by effectively reducing the potency of the essential oils, allowing for a safer application on the skin. Additionally, carrier oils can hydrate and nourish the skin, making them beneficial in enhancing the overall efficacy of the aromatherapy treatment.

Carrier oils also play an essential role in the distribution of essential oils during application, helping to facilitate a smoother texture and ease of spread on the skin. This combination of dilution and moisturizing benefits makes them an integral part of aromatherapy practices.

The other choices do touch on important aspects of aromatherapy but do not align as closely with the core purpose of carrier oils. Enhancing fragrance, preserving shelf life, and promoting absorption are functions more specific to certain contexts or practices within aromatherapy rather than defining the primary role of carrier oils.
