Linoleic Acid or Omega 6 and Linolenic Acid or Omega 3 are "essential" fatty acids or EFA1Essential Fatty Acids and Skin Health. EFAs belong to the group of membrane forming phospholipids and are essential for rebuilding and producing cells. Omega 3 fatty acids are critical components of cellular and membrane lipids. Omega 6 is part of Ceramide I, which is the most important barrier substance in the epidermal layers.
EFAs are natural polyunsaturated essential free fatty acids. Products containing EFAs are appropriate for individuals suffering from neurodermitis as their skin generally shows a Ceramide I deficiency. EFAs nurtures, protects and acts as a skin conditioner. It is particularly suitable for the treatment of dry, stressed and sensitive skin, potently supporting the skin in re-building and maintaining its natural healthy structure and functionality. EFAs also strongly acts as a hair conditioner and reduces hair breakage.
In oils, Omega 3 and Omega 6 are intertwined with other fatty acids as a triglyceride. In order to get the benefits of the EFA the body needs to break down the triglycerides and free the EFAs. So applying an oil high in linoleic acid does not equate to skin goodies but the efficacies of linoleic acid takes time to break free.
Linoleic acid is anti-inflammatory, and has been shown in studies to reduce the occurrence of comedones, as well as lighten hyperpigmentation. It has a critical role in structural integrity and barrier function of the skin.
Some of the oils high in Linoleic Acid are Black Currant, Black Seed, Borage, Chardonnay Grape, Evening Primrose, Grape Seed, Hemp Seed, Papaya Seed, Passion Fruit Seed, Red Raspberry, Safflower Seed Oil (High Linoleic), Soybean, Wheat Germ.
Benefits to the skin include the treatment of dry skin, repairs and maintains the skin’s natural barrier function, makes skin smoother and healthier. In hair, they effectively counteracts hair weathering and aging, improves hair combability and condition, protects hair against heat and reduces hair breakage.
