Linum Usitatissimum (Flax) Seed Extract
What is Linum Usitatissimum (Flax) Seed Extract?
Linum Usitatissimum (Flax) Seed Extract is derived from the seeds of the flax plant, an annual herb native to regions like the Mediterranean and Asia. These seeds are rich in polysaccharides, omega-3 fatty acids, and lignans, extracted via water or solvent methods for cosmetic use. Primarily functioning as a skin conditioning agent, it forms a breathable film on the skin surface to help retain hydration, improve texture, and enhance barrier flexibility. Commonly incorporated into moisturizers, serums, and masks at low concentrations, it provides emollient properties that smooth rough areas without greasiness. Its botanical composition contributes to a protective, nurturing effect in formulations targeting daily skin maintenance.
