Olea europaea fruit oil is an emollient plant oil with benefits similar to several other non-scented plant oils. It is beneficial for dry skin due to its fatty acid content, some of which comes from the emollient squalene.
Olea europaea fruit oil contains essential fatty acids that dry skin needs, including oleic, palmitic and linoleic acids. It also contains phenolic compounds that provide antioxidant benefits. A small number of animal studies show that topically applied olive oil can protect against environmental damage. https://www.paulaschoice.com/ingredient-dictionary/ingredient-olea-europaea-fruit-oil.html?q=Olea%20Europaea%20Fruit%20Oil&fdid=ingredients
