Sesame seed oil contains high levels of polyunsaturated fatty acids (notably linoleic and oleic acids), natural antioxidants such as sesamin, sesamol, and vitamin E, which collectively protect cell membranes from oxidative damage and support skin barrier repair. The oil’s anti-inflammatory effects result from modulation of pro-inflammatory cytokines and inhibition of lipid peroxidation. Topically, sesame oil replenishes essential lipids, enhancing skin hydration and elasticity. Orally, its antioxidant and lipid-lowering effects contribute to cardiovascular protection by improving lipid metabolism and reducing systemic oxidative stress.
