Phytosterols, also called plant sterols, are natural compounds found in many plant-based foods (nuts, seeds, green vegetables, vegetable oils). In cosmetics, their interest lies in their structural similarity to skin cholesterol, one of the essential lipid components of the intercellular cement of the stratum corneum.
This structural similarity is documented in scientific literature as a factor promoting their integration into the skin's lipid structures. By integrating into the intercellular cement, phytosterols are linked, according to available data, to supporting skin comfort and preserving hydration comfort against external factors such as cold, pollution, and climate variations.
Their soothing properties are documented and linked to visible reduction of redness and comfort for sensitive or compromised skin. This complementary soothing action makes them suitable for reactive or discomfort-prone skin.
Phytosterols are also linked, according to available data, to supporting mechanisms involved in maintaining skin structure, related to visible suppleness and comfort of mature skin whose stratum corneum lipid composition evolves over time.
Their tolerance profile is well documented, with particular adaptation to dry or compromised skin seeking daily comfort and suppleness.
In summary, biomimetic plant lipids documented for their contribution to skin comfort, hydration comfort, and soothing properties, suitable for dry, sensitive, or mature skin.
