Phytosterols

Phytosterols are plant-derived lipids found in oils, seeds, nuts, and grains. Structurally, they’re similar to cholesterol, which helps explain why they’re so useful in skincare and haircare. In formulas, they’re often included to support the skin barrier, help reduce the feel of dryness, and improve softness and comfort. They can also act as soothing helpers in products aimed at skin that feels stressed or easily irritated.

For skin, phytosterols are valued for their barrier-supporting and conditioning properties, making them a good fit for dry, rough, or mature skin, as well as formulas designed to feel nourishing without being overly heavy. In hair products, they may help improve manageability and add a smoother, more conditioned feel. They’re usually well tolerated, but as with any ingredient, individual sensitivity is possible. Their effects are supportive rather than dramatic, so they work best as part of a well-rounded formula.
