Science
Mechanism of Action
This ingredient functions by delivering a complex array of unsaponifiable compounds, including beneficial sterols, squalene, and fat-soluble vitamins, directly to the skin. These bioactives integrate into the skin's lipid matrix, bolstering the epidermal barrier. This action provides significant emollient properties, reduces transepidermal water loss, and offers essential nourishment, contributing to overall skin health and resilience.
