Used for
Soft, comfortable-feeling skin
How it works
Linseed, also called flax (Linum usitatissimum), is a slender crop plant grown for its small, glossy seeds. An extract of the seeds contains plant phenolic compounds and flavonoids, and it is used in skincare as a gentle, conditioning ingredient.
Laboratory tests have shown flaxseed extract to have antioxidant activity, and a gel made with it has been studied on skin for moisture and elasticity.

Questions
Is linseed the same as flaxseed?
Yes. Linseed and flax are two common names for the same plant, Linum usitatissimum, and both names are in everyday English use. It is a single species, grown for its seeds, its oil and its stem fibre. (USDA GRIN)
What is linseed extract?
It is an extract of linseed (flax) seeds. Analysis of flaxseed extracts shows they contain plant phenolic compounds and flavonoids with antioxidant activity in laboratory tests. The seeds also hold mucilage, a material rich in polysaccharides that turns into a soft, viscous gel when it meets water. (Tasneem et al., 2022; Knott and Diehl, 2026)
Is there research on linseed extract for skin?
Yes. In a study on skin, a gel containing flaxseed extract was compared with a placebo gel, and skin moisture and elasticity results favoured the extract. (Tasneem et al., 2022)
About the plant
Flax, Linum usitatissimum, is known only in cultivation, with no recorded wild native range. It is grown for its seeds, its oil and the fibre in its stems. (USDA GRIN)
The small seeds are the part used for the extract. They carry mucilage, made mainly of acidic polysaccharides, which forms a viscous gel when it gets wet. (Knott and Diehl, 2026)
