It is one of two essential fatty acids humans must obtain through diet. It is also the most abundant fatty acid found in skin’s epidermis. The body uses linoleic acid to make gamma linolenic acid (GLA), which plays a role in modulating inflammation. In cosmetics, it is used as an emollient and thickening agent. In addition, research shows it to be effective as a skin restorative, an antioxidant, and as a skin-soothing agent. There are even some studies demonstrating that it could have some discolouration fading properties due to its ability to inhibit excess melanin production. Since linoleic acid is a component of many edible oils, the U.S. Food and Drug Administration has ruled it safe as a direct and indirect food additive. In personal care products, it is used in amounts up to 21.8% in rinse-off cleansing products and 3.4% in leave-on products.
