When we think of linen, we think of fabric… No wonder, because since ancient Egypt, these fibers have been used to make clothes. In the Bible, there are even many references to this matter. At the end of the 19th century, cotton made its appearance and… dethroned linen. But this little blue flower has many other uses. With the seeds of its fruits, a flour is made which is used in pharmacies to make poultices. An oil is also extracted from it which, among other things, protects and strengthens the wood.
In cosmetics, we mainly find flax seed extracts in softening, moisturizing or restorative treatments, chosen for their film-forming properties. Thus, “flax flower, which does not have any particular scent, is often present in shower gels, in order to provide a guarantee of softness to the products”, analyzes Bernard Fabre, phytochemist, head of the plant products laboratory. for Klorane.
In winter, an anti-tightening solution
Flaxseeds are rich in polysaccharides (complex sugars) which have the particularity of retain water in the skin and in mucilages, slightly thick molecules which remain on the surface to seal the gaps in the epidermis. The oil extracted from these seeds polymerizes on contact with air.
“The oil hardens and forms a protective film on the surface”, specifies Bernard Fabre. This layer covers the holes in the weakened stratum corneum, which regains its impermeability and thus slows down dehydration. “It leaves a silky envelope with a particularly soft and pleasant touch on the epidermis”, continues the specialist. By restoring the hydrolipidic barrier, linen at the same time soothes feelings of irritation and discomfort. Emollient, it softens the tissues and relieves tightness due to an inflammatory reaction.
More firmness, less looseness
Linen gives the face more density, “pulpy”. It stimulates the synthesis of glycosaminoglycans, of which thehyaluronic acid. These essential macromolecules retain water in the different layers of the skin, like a sponge. Thanks to them, the support mattress is reinflated and its elasticity is improved. Flax also forms a protective film around the collagen, which protects it from oxidation and any degradation. It thus delays skin slackening due to tissue ageing.
Hair that regains its luster
These redensifying properties are not reserved for the face, because flax allows you to flesh out hair that is too fine. Since “flax mucilages are precious for thickening and also sheathing the hair”, adds Bernard Fabre. In fact, they surround the hair fiber to increase its diameter. And as they stiffen, they provide hold andfullness in the hair, kind of like a tutor. Less fluff, the hair is easier to style and regains its luster.
Health benefits too
If this plant has many virtues in local application, it is also very interesting when it is taken orally. Because flax seeds are very rich in omega-3, and in particular in alpha-linolenic acid. This essential fatty acid is not produced by the body. However, it consolidates the cutaneous barrier and contributes to a good skin hydration. It also has an effect on depression and improves morale. Finally, the hygroscopic qualities of linen facilitate digestion and relieve episodes of constipation. This is why it is also credited with slimming properties.
