Linoleic Acid
Linoleic acid is an essential omega-6 fatty acid commonly found in many plant oils. In skincare and cosmetics it acts as a gentle moisturiser and helps strengthen the skin’s natural barrier. It is a popular ingredient in creams, serums and oils for those seeking softer, healthier-looking skin.
How it works in skincare
In cosmetics linoleic acid works as an emollient that helps replenish the intercellular lipids in the stratum corneum, supporting the skin’s protective barrier and reducing moisture loss. It is readily absorbed and integrates well into the skin’s own lipid matrix, leaving a smooth, non-greasy finish. Its lightweight texture makes it ideal for both leave-on treatments and rinse-off products where it contributes to softness and improved suppleness.
