Virgin borage oil can be used internally (alone or mixed with other oils for salad dressing) or externally (by massage, rubbing). The richness of virgin borage oil lies in gamma-linolenic acid (~20%). This acid is said to be essential because it is rarely found in nature (exception: virgin evening primrose oil) and above all it is not synthesized by the body. A supplementary internal and external intake is therefore strongly recommended; this essential fatty acid is necessary for maintaining the structure of the cell membrane. Therefore, it contributes to the maintenance, suppleness and beauty of the skin. These fatty acids are essential for the formation and renewal of certain so-called short-lived regulatory substances (in particular prostaglandin E1) which continuously control cell activity.
