Carrier oils which are also known as oil bases or vegetable oils are an essential part of aromatherapy. They're extracted from the fatty portion of a plant, such as the kernels, seeds, or the nuts. Carrier oils are used to dilute essential oils and other oils before applying them to your skin, which is where the term ‘carrier oil’ derives from, 'carrying' the oil on to the skin.
This type of oil contains fat soluble minerals, vitamins, and other nutrients and can provide different therapeutic properties. In terms of the best choice of carrier oil, this entirely depends on the therapeutic benefit, colour and the overall aroma that you want to achieve. You will find carrier oils in creams, body and bath oils, lotions, lip balms and other moisturising skin care products.
