What is this
Lecithin
Lecithin is a naturally occurring blend of phospholipids, most often sourced from sunflower or soybean. Because phospholipids are building blocks of the skin's own lipid barrier, lecithin is used in skincare to replenish, soften and help skin hold moisture, while lending formulas their silky, unified texture.

Questions about lecithin
What is lecithin in skincare?
Lecithin is a natural mixture of phospholipids — the same family of lipids that structures every cell membrane and the skin's own barrier. In cosmetics it is usually derived from sunflower or soy and appears in serums and creams as a conditioning, harmonizing ingredient.
What does lecithin do for skin?
It softens, conditions and helps skin retain moisture, supporting a supple, comfortable feel. Because its phospholipids resemble the skin's own lipids, it integrates beautifully rather than sitting on the surface — while also helping oil and water phases in a formula stay elegantly united.
Is lecithin good for dry or sensitive skin?
Yes — it is gentle, non-irritating and particularly appreciated by dry, delicate skin, where its replenishing phospholipids help ease the feeling of tightness and support the skin's moisture barrier.
Why is lecithin in so many fine formulations?
Formulators love it twice over: for the skin, it is a softening, moisture-supporting lipid; for the formula, it is a natural emulsifier that creates fine, silky textures. That double role — active and architect — is why it appears in The Nine Aurora's serums.
