What is a Base Oil?

The term base oil often refers to pure vegetable oils used in aromatherapy and skincare.
At MESACOSA Co., Ltd., we go beyond single-ingredient oils. We lend carefully selected plant-based oils according to different skin types to create customized base oils, also known as carrier oils.
These oils serve as the foundation for diluting essential oils and enhancing skin compatibility and absorption.

What is a Carrier Oil?

A carrier oil is a vegetable oil used to deliver essential oils safely to the skin, especially during aromatherapy massage.
The term "carrier" comes from its function of carrying the essential oil into the body through the skin.
Carrier oils are also referred to as fixed oils, because unlike essential oils, they are non-volatile, and remain stable under heat and light.
They help dilute essential oils, reduce evaporation, and enhance absorption, making them an essential component in safe and effective aromatherapy.

An Easy Way to Use Essential Oils
One of the most convenient ways to use essential oils is by diluting them in a cream base or a suitable carrier oil.
We recommend using a fragrance-free cream base or a skin-type-specific base oil together with your chosen essential oils.
Simply blend according to your desired purpose — whether it's for relaxation, skin care, or revitalization — and enjoy personalized aromatherapy at home.
