Coffea arabica (coffee) seed oil
The concentrated oil from the coffee bean plant, which is green, not dark brown as this color doesn't occur until coffee beans are roasted. Research on this oil's effect on skin is intriguing. In vitro tests on skin samples and sections of human skin have shown topical application can help restore skin and contribute to a healthier, smoother look and feel. This non-fragrant plant oil also appears to stimulate pathways in skin that lead to greater moisture retention.
Although that news is encouraging, at this point there's little research to go on. However, coffee seed extract and oil are a rich source of antioxidants whether consumed (as in beverages) or applied to skin. We're hopeful that ongoing research will reveal all forms of coffee to have benefits for skin.
