What is LINUM USITATISSIMUM SEED EXTRACT used for?

Linum Usitatissimum Seed Extract is a plant-derived ingredient that delivers both hydration and antioxidant protection - making it a versatile choice for nourishing skin and strengthening hair in a gentle, natural way. 

For skin: Flaxseed extract is particularly beneficial for dry, sensitive, or mature skin due to its high mucilage and omega-3 content. The mucilage forms a light, breathable film on the skin that helps lock in moisture, while the fatty acids support the skin barrier and reduce transepidermal water loss. The antioxidants present in Linum Usitatissimum Seed Extract help fight free radical damage, making it useful in anti-aging formulations. The extract also exhibits anti-inflammatory effects, helping to soothe redness, irritation, and skin discomfort. 

For hair: In hair care, Linum Usitatissimum Seed Extract functions as a natural conditioner and scalp soother. It enhances shine, smoothness, and manageability without weighing the hair down. This extract is ideal for calming dry, itchy scalps and is especially valuable in formulations for curly, textured, or damaged hair that requires both softness and structure.

Origin

Linum Usitatissimum Seed Extract comes from flaxseeds, which are first thoroughly cleaned and ground. This powder is then soaked in distilled water and gently heated to form the extract. The final product is filtered and preserved. It may also be concentrated, if required.
