Linoleic Acid

Linoleic Acid is an essential omega-6 polyunsaturated fatty acid with 18 carbons and two double bonds, predominantly sourced from safflower, sunflower, and grape seed oils. It's particularly valued in cosmetic formulations for its ability to reinforce the skin's barrier function and reduce transepidermal water loss, as it's a natural component of ceramides in the stratum corneum. Formulators choose it not only for its emollient properties but also for its role in maintaining skin health, as deficiency in linoleic acid is associated with barrier dysfunction and inflammatory skin conditions.
