Linum Usitatissimum (Linseed) Seed Extract
Linum Usitatissimum (Linseed) Seed Extract, also known as flaxseed extract, is a gentle, plant-derived ingredient valued in UK skincare and haircare for its soothing and conditioning properties. Rich in natural polysaccharides and lignans, it helps skin feel soft and hydrated while adding smoothness to hair. It is commonly found in moisturisers, serums, masks and hair treatments.
How it works in skincare
In cosmetics and skincare, Linum Usitatissimum (Linseed) Seed Extract functions primarily as a skin-conditioning agent and humectant. The extract’s natural mucilage forms a light, flexible film on the skin that helps reduce moisture loss while imparting a silky feel. It also calms the appearance of redness and irritation, making it a popular choice in sensitive-skin formulations, leave-in hair conditioners and anti-frizz products.
