Soybean Sterols
Glycine Soja Sterols
Soybean Sterols are plant-derived sterols extracted from soybean oil that help support the skin's natural barrier and improve moisture retention. They are structurally similar to cholesterol, a lipid naturally found in the skin, allowing them to reinforce the skin barrier and reduce moisture loss. They also act as emollients, leaving the skin feeling softer and smoother, and are commonly used in moisturisers, barrier repair creams, and products for dry or sensitive skin.
🛡️
Safety: Generally well tolerated by most skin types. Individuals with a known soy allergy should exercise caution, although highly purified cosmetic sterols are unlikely to contain significant soy proteins.
