There is never a dull moment in the skin care industry (pun intended). We find that there are tons of properties that keep our skin healthy and glowing.
Oleic acid is a monounsaturated fatty acid that provides the human body with numerous types of health benefits. Oleic acid is a fat that your body produces, which in fact, is even found in human sebum, and is an omega nine fatty acid found in its natural form in many different food items such as animal products and vegetable sources.
Triglyceride esters of the oleic acid are among the most important components of olive oil so that is why olive oil, along with canola oil and grapeseed oil is one of the best sources of oleic acid. Oleic acid may also occur naturally in the adipose tissue of the human body. It is one of the healthiest sources of fat and it can be used as a healthy alternative for different types of highly saturated animal fats. The best sources of oleic acid include macadamia nuts, pecans, peanuts, hazelnuts, butter, pistachio nuts, sesame oil, almonds, peanut oil, sunflower oil, cashews and avocados.
You will also sometimes find oleic acid featured in skincare products. It is promoted as having various advantages, such as reducing wrinkles or fighting oxidation. It is also suggested that oleic acid in the diet may offer skin benefits.
Oleic Acid and the Benefits for Your Skin
Oleic acid is a godsend for dry, aging skin since it penetrates easily and deeply into the skin’s surface. Oils high in oleic acid are richer and heavier in consistency. They are extra-occlusive and seal in moisture well. Oleic acid is absorbed well by the skin, which moisturizes your skin and will also strengthen your hair. It also has anti-inflammatory and skin softening properties.
Boasts Antioxidant Powers to Fight Off Wrinkles - Oleic acid comprises antioxidant compounds that help fight free radical damage caused by environmental aggressors like UV rays, the top trigger of premature aging. By minimizing free radicals in skin, so too is the manifestation of wrinkles, fine lines, dark spots, sagging and other unwanted features.
Promotes Healing and Repairing - As an anti-inflammatory substance that stimulates wound healing, oleic acid can also help calm, balance and help repair skin, even those with damaged conditions like eczema, rosacea and psoriasis. Oleic acid also contains compounds that reinforce the integrity of cell membranes.
- Oleic acid is the primary omega 9 fatty acid.
- Omega 9's can be produced by the body but are also beneficial when obtained in food. Found in vegetable, nut and seed oils.
- Metabolism of linoleic acid and a-linoleic acid is limited in the skin. They are considered essential nutrients for the skin.
- Omega 6 polyunsaturated fatty acids play an important role in the structural integrity and barrier function of the skin.
- Both topical and oral supplementation are effective ways to deliver essential fatty acids to the skin.
- A significant portion of ingested essential fatty acids may be oxidized by the liver before reaching peripheral tissues. This means topical application can be a more efficient route of delivery for skin effects.
