What it is
An essential omega-6 polyunsaturated fatty acid found abundantly in plant oils such as safflower, sunflower, and grapeseed, used in skincare as a lightweight emollient and skin-conditioning agent. It is a key structural fatty acid in the skin's own lipid barrier.
How it works
Linoleic acid is incorporated into ceramides and other intercellular lipids of the stratum corneum, helping reinforce the barrier and reduce transepidermal water loss, and its unsaturated structure gives a lighter, less greasy feel than saturated fats.
