O like Olive oil (Olea Europaea)

Olive oil is rich in essential fatty acids, omega 9 but also unsaponifiable.

Unsaponifiable, these active ingredients that do not turn into soap with soda :) and are so good for the health for their antioxidant properties (Vit E, phenols ...)
And by the way, we do eat extra virgin oil every day... and our skin should be jealous!
