Science
Mechanism of Action
This ingredient operates by reinforcing the dermal barrier and actively inhibiting transepidermal water loss. It serves as a key precursor in the biosynthesis of essential ceramide molecules, which are fundamental for robust barrier function. Furthermore, it optimizes lipid organization within the lamellar structures of the stratum corneum and supports the proper functioning of lamellar bodies, responsible for packaging and transporting barrier lipids. Beyond its barrier-strengthening capabilities, it exhibits targeted antimicrobial properties, particularly against Propionibacterium acnes, along with anti-inflammatory and soothing effects that help regulate epidermal cell growth and differentiation.
