Barrier-restoring lipids. Safe.
Phytosterols are plant sterols, structurally close to cholesterol, a key lipid of the skin barrier. INCI: Phytosterols. In a formula they work as a barrier-support component and soothing agent: they integrate into the intercellular lipids of the stratum corneum, help hold water, and reduce irritation. Cholesterol and sterols are part of the skin's lipid cement, so phytosterols have a meaningful barrier rationale, especially for dry and reactive skin. They are a useful supporting component rather than a potent active. Pregnancy safety. Topical use is systemically negligible, with no evidence of harm. They can be used during pregnancy and lactation. Tolerance. Irritation and allergen potential are low, suitable for dry and sensitive skin.
