Grape (Vitis Vinifera) seed oil is an organic skincare ingredient expressed from grape seeds. This rich, soothing carrier oil imparts shine and is widely used in hypo-allergenic and organic skincare products because it does not cause allergic reactions.
Organic skincare products containing grapeseed oil and grapeseed extract contain a very high level of antioxidant vitamin E (60 to 120 mg per 100 g). This fat-soluble antioxidant prevents injury to cell membranes.
This incredible ingredient also contains resveratrol, another powerful antioxidant with antimicrobial, skin whitening, and sooting (anti-inflammatory) properties. Particular molecular forms of oxygen called reactive oxygen species (ROS), are highly toxic to all biological systems. They arise whenever oxygen and water are present. People usually do not know that UV light is a powerful generator of ROS and thus causes premature skin aging, for example, while sunbathing. Compounds that can capture and neutralize ROS are called antioxidants.
Oil includes a blend of procyanidins from grape seeds and natural vitamin E (tocopherol). These grape polyphenols are responsible for the well-known cardiovascular-health-promoting activity of red wine. Moreover, they figure among the best natural, water-soluble antioxidants. On the other hand, Vitamin E is a highly efficient oil-soluble antioxidant. Moreover, procyanidins and vitamin E act synergistically to protect against ROS.
In addition, Vitis Vinifera oil increases skin tolerance to UV exposure. A clinical study with a cream containing grape seed oil. The forearms of 12 volunteers were treated twice daily for ten days. The minimal erythemal dose (MED) was analyzed at the beginning and end of the treatment. The MED for the grapeseed oil did treat the skin area was 12% higher at the end of the study.
