Science
Mechanism of Action
This phytosterol derivative primarily functions by strengthening the skin's protective barrier and delivering substantial emollience. It actively supports the hydrolipidic film, which significantly limits transepidermal water loss and thereby prevents dryness and flaking. Derived from sunflower seed oil, its composition includes linoleic acid that is understood to enhance keratinocyte proliferation and lipid synthesis, directly contributing to skin barrier repair and improved moisture retention.
