The oil coming from the seeds of a flowering plant called Camelina or Gold of pleasure. Similar to lots of other plant oils it's loaded with nourishing and moisturizing fatty acids.
What's not so similar to other oils, though, is that it's a very rich source (30-40%) of fairly rare Alpha-linolenic acid (aka omega-3) and contains only less of the more common linoleic (15-24%) and oleic acids (10-16%). Alpha-linolenic acid is a very important one with anti-inflammatory properties and the lack of it can cause continuously dry skin.
Other than fatty acids, Camelina oil also contains antioxidant vitamin E (54-78mp/100g), as well as more than usual amounts of moisturizing cholesterol and a phytosterol called brassicasterol.
All in all, a goodie plant oil that's especially recommended for dry and sensitive skin types.
