Facial oils work with your skin, not against it. The outermost layers of your skin are oil-based, which makes a facial oil the perfect treatment. These top layers are primarily composed of fatty acids, cholesterol, and ceramides, all of which can be found in natural oils.

Facial oils help to repair skin's barrier function and should be used to seal in your moisturizer and not used as a moisturizer.

The outermost layers of skin are oil-based in order to keep your skin safe from germs and dehydration. You can think of your skin as the shield of your body. When this shield is attacked or neglected, it becomes:
Less able to do its jobs of protection, temperature regulation, and so forth
Dull and dehydrated
Dry and unevenly textured
Open to developing forms of dermatitis and eczema Sensitive, reactive, and reddened.

Facial oils help keep your skin healthy and attractive because they replenish your skin's natural oil content. Oils not only form a temporary barrier, but they also feed skin with the nutrients it needs to restore itself to health.
