Linum Usitatissimum Seed Oil (Flaxseed Oil)

Linum Usitatissimum Seed Oil is a plant-derived emollient oil expressed from flax (linseed) seeds and valued in cosmetic formulations for its skin-conditioning and lipid-replenishing benefits. Naturally rich in polyunsaturated fatty acids—especially alpha-linolenic acid (omega-3), along with linoleic acid (omega-6)—it helps support a softer, more supple feel and can reinforce barrier-comfort concepts by reducing the look of dryness and roughness. In addition to its emollient profile, it may provide antioxidant-support through naturally occurring minor components, though composition can vary with processing and refinement. Flaxseed oil is commonly used in facial oils, serums, creams, body lotions, balms, and lip care, as well as in hair and scalp treatments where it can enhance smoothness and improve the feel of manageability. Because highly unsaturated oils can be more oxidation-prone, formulations often incorporate antioxidants and protective packaging strategies to help maintain stability and sensory quality over time.
