Linoleic acid can be found in a variety of skincare products, including facial oils, serums, and moisturisers. You can also get it through your diet by eating linoleic acid-rich foods like nuts, seeds, and vegetable oils. In this blog, we will explore the numerous linoleic acid skin benefits including how linoleic acid helps maintain skin barrier and retain moisture to prevent dryness along with how to use it in your daily skincare routine.
What is Linoleic Acid
Linoleic acid is a polyunsaturated fatty acid that is essential for human health. It is an omega-6 fatty acid, meaning that the first double bond in its carbon chain is located six carbons from the omega end, or the methyl end, of the molecule.
Linoleic acid is not produced by the human body and must be obtained through the diet. It is found in many vegetable oils, including sunflower oil, safflower oil, corn oil, and soybean oil, as well as in nuts and seeds.
In the body, linoleic acid is converted into other important compounds, including arachidonic acid, which plays a role in inflammation, and eicosanoids, which are involved in a wide range of physiological processes, including blood clotting, immune function, and the inflammatory response.
Research has shown that consuming adequate amounts of linoleic acid can help lower the risk of heart disease and other chronic illnesses, and it is often included as a key nutrient in dietary guidelines. However, like all nutrients, too much linoleic acid can have negative effects, and the optimal intake level is still a matter of ongoing scientific investigation.
Benefits of Linoleic Acid
Linoleic acid is an essential fatty acid that is necessary for good health. It is an omega-6 fatty acid that is required for many bodily functions but cannot be produced by the body on its own. Linoleic acid is only available through diet or supplements. Linoleic acid has several advantages.
-
Skin health: Linoleic acid is important for maintaining healthy skin. It helps to maintain the integrity of the skin barrier, which can help to prevent water loss and keep skin hydrated. It also has anti-inflammatory properties that can help to reduce redness and irritation.
-
Brain health: Linoleic acid is important for brain development and function. It is a key component of the myelin sheath that surrounds and protects nerve fibers in the brain. It is also involved in the production of neurotransmitters that are important for mood, memory, and learning.
-
Cardiovascular health: Linoleic acid can help to reduce the risk of heart disease. It has been shown to lower levels of LDL (bad) cholesterol, which can help to prevent the buildup of plaque in the arteries. It can also help to lower blood pressure and reduce inflammation.
-
Immune function: Linoleic acid is important for maintaining a healthy immune system. It helps to regulate the production of cytokines, which are important for immune function. It also has anti-inflammatory properties that can help to reduce inflammation in the body.
-
Weight management: Linoleic acid may help with weight management. It has been shown to increase the production of hormones that promote satiety, which can help to reduce food intake. It may also increase the body's ability to burn fat.
It is important to note that, while linoleic acid is beneficial to health, too much of it can be harmful. It is critical to consume linoleic acid in moderation and to eat a well-balanced diet.
Linoleic Acid for acne prone skin
Most people who get breakouts have an excess of Oleic Acid, a (non-essential) Omega-9 fatty acid that helps the skin lock in and retain moisture but can easily get trapped in pores when not properly balanced with Linoleic Acid. Whereas Oleic Acid is quite rich, causing excess oil in acne-prone skin, Linoleic Acid is much thinner and lighter, making it suitable for those with oily/acne-prone skin.
Research has shown that applying linoleic acid topically can help reduce inflammation and acne lesions. In fact, one study found that applying a facial oil containing linoleic acid for 4 weeks significantly reduced the number of acne lesions in participants.
If you have acne-prone skin, incorporating products that contain linoleic acid into your skincare routine may be helpful. Look for facial oils or moisturizers that contain high levels of linoleic acid or consider adding a pure linoleic acid supplement to your regimen.
It's worth noting that while linoleic acid can be helpful for managing acne, it's important to address the root causes of your acne, which can include hormonal imbalances, diet, and lifestyle factors. Consult with a dermatologist if you have persistent acne.
How to layer/mix Linoleic Acid with other skin care ingredients
Linoleic acid is an omega-6 fatty acid that can be beneficial for the skin when used topically. It can help to improve the skin's barrier function, reduce inflammation, and regulate sebum production. Here are some tips for layering/mixing linoleic acid with other skincare ingredients:
-
Use it as a carrier oil: Linoleic acid is a great carrier oil, meaning it can be used to dilute other essential oils or actives. It has a light texture and is easily absorbed by the skin. You can mix linoleic acid with other carrier oils, such as jojoba oil, sweet almond oil, or rosehip oil, to create a custom blend that suits your skin's needs.
-
Mix with water-based products: Linoleic acid is an oil, so it's not soluble in water. However, you can mix it with water-based products such as toners, essences, or serums. To do this, add a few drops of linoleic acid to your water-based product and mix well before applying to the skin.
-
Layer it with other actives: Linoleic acid can be layered with other skincare actives to enhance their benefits. For example, you can layer it with niacinamide to help regulate sebum production and reduce inflammation, or with vitamin C to boost collagen production and brighten the skin. Make sure to check the pH and compatibility of the ingredients before layering them.
-
Use it as a stand-alone product: If you have sensitive skin or prefer a minimalist skincare routine, you can use linoleic acid as a stand-alone product. Apply a few drops of linoleic acid to your face after cleansing and toning, and before moisturizing. This can help to hydrate and nourish the skin without overwhelming it with too many products.
It's always a good idea to patch-test new products or combinations of products before applying them to your entire face, especially if you have sensitive skin. Start with a small area, and if there's no adverse reaction after a day or two, you can gradually introduce the product to your entire routine.
