High-linoleic plant oil. One of the best-studied barrier-supportive oils for compromised skin.
What it does
Sunflower oil is around 60–70% linoleic acid, which makes it a strong fit for the skin barrier's natural fatty-acid profile. Pediatric-dermatology research supports its use on infant skin to help maintain barrier function. The fatty-acid profile is what matters here — high-linoleic sunflower oil is the cosmetic version; the high-oleic culinary version is a different fatty-acid balance.
The evidence, graded
strongThe skin's barrier is built from ceramides, cholesterol, and free fatty acids in a roughly 1:1:1 to 3:1:1 ratio. Moisturizers formulated to mimic that ratio support barrier repair more than any one lipid alone.Man 1996 · Journal of Investigative Dermatology ↗
