Science
Mechanism of Action
Sesamum Indicum Seed Oil functions primarily as an emollient, moisturizer, and occlusive agent. Its fatty acid profile helps to fortify the skin's hydrolipidic barrier, creating a film on the epidermis that effectively limits transepidermal water loss and traps moisture, leading to deep hydration and skin softening. Rich in antioxidants such as sesamol, sesaminol, vitamin E, and various phenolic compounds, it actively combats free radical damage and protects against premature aging. Furthermore, this oil exhibits anti-inflammatory and antimicrobial properties, aiding in the reduction of irritation and promoting accelerated skin cell growth for wound healing, while also offering mild natural UV protection.
