Riley Keough, Gwyneth Paltrow, and Hailey Bieber All Use This One Face Oil

Here it is—the MARA Algae + Moringa Universal Hydrating Face Oil. It includes wild-collected algae, moringa, and watermelon. The first plumps the skin and softens the look of fine lines and wrinkles. The second contains nutrients and antioxidants to moisturize the skin and do away with dullness. Finally, the third hydrates the skin and provides fatty acids and vitamins. 

The brand says you can use it on its own, or layer it on top of serums and creams to lock moisture in. You can even mix it with makeup for a dewy finish and use it as a natural light-reflecting highlighter on the tops of the cheekbones (we love a multi-tasking beauty product).
