Emollient plant oil (Latin name Olea europaea) with benefits similar to those of several other non-fragrant plant oils. Olive oil is beneficial for dry skin because of its fatty acid content, some of which comes from the emollient squalene. Olive oil contains essential fatty acids dry skin needs, including oleic, palmitic, and linoleic acids. It also contains phenolic compounds that provide antioxidant benefit. A small number of animal tests show that topically applied olive oil can protect against environmental damage. [1,2]
This plant oil maintains a low potential for sensitivity. [1,2] To be very clear: When olive oil is mixed in a formula in small amounts with other beneficial ingredients, you get the benefit of its slip and emollient properties along with some antioxidant benefit. The negative effects of olive oil are apparent only when used alone on skin.
