Linum Usitatissimum (Linseed) Seed Oil
Linum Usitatissimum (Linseed) Seed Oil, also known as flaxseed oil, is a nutrient-rich plant oil commonly used in UK skincare and haircare. It is prized for its high levels of essential fatty acids and natural antioxidants that help nourish and soften skin and hair. Gentle enough for daily use, it is a popular ingredient in natural and clean beauty formulas.
How it works in skincare
In cosmetics and skincare, Linum Usitatissimum (Linseed) Seed Oil functions as an emollient and skin-conditioning agent. Its high content of alpha-linolenic acid and other polyunsaturated fatty acids helps replenish the skin’s lipid barrier, reducing moisture loss while imparting a smooth, non-greasy feel. It is frequently included in facial oils, moisturisers, hair masks and serums to improve suppleness and provide a healthy-looking glow.
