“An essential omega-6 fatty acid that is often deficient in acne-prone skin.”
What it does
Linoleic acid is an essential omega-6 fatty acid that cannot be synthesised by the body. It is a key structural component of ceramides and the skin's lipid barrier. Research shows that acne-prone skin is often deficient in linoleic acid (and relatively high in oleic acid), making topical application particularly beneficial. Found naturally in sunflower, rosehip, and grapeseed oils.

- Replenishes essential fatty acids in the skin barrier
