What Is Phytosterols?
Phytosterols are naturally occurring, cholesterol-like molecules found in all plant foods; the highest concentrations are found in vegetable oils such as canola, peanut, safflower, and sesame. Overall, nuts, seeds, and legumes are excellent sources of phytosterols, both for the body and for skin. When applied topically, phytosterols can both soothe and moisturise skin.
Soy phytosterols in particular can help replenish and restore ageing skin, keeping it pliant and supple. The usage level of phytosterols in cosmetics typically falls between 0.5–2%; however, higher amounts may be used if desired.
