olive oil (Olea europaea) is a carrier oil with excellent lubricity, pale color, and low odor. olive oil is considered an especially good carrier for essential oils. It is a good emollient and can also be used for perfuming. Its unsaponifiable fraction is described also as a type of precursor, although not a biological one, with some claims of its targeting epidermal keratinocytes and stimulating the synthesis of such substances as collagen, elastin, proteoglycans, and glycoproteins.
