Science
Mechanism of Action
This bioactive peptide functions by mimicking decorin, an extracellular matrix protein vital for controlling collagen aggregation and maintaining optimal collagen fiber packing. It actively modulates fibrillogenesis and collagen fibril dimensions, promoting the formation of thinner, more uniform collagen fibers and bolstering overall collagen stability. Beyond structural refinement, Tripeptide-10 Citrulline also stimulates general collagen synthesis, contributing to improved skin elasticity and a smoother complexion. Furthermore, it fortifies the skin barrier by encouraging the production of key proteins involved in moisture retention and exhibits antioxidant properties, offering defense against free radical damage.
