Science

Mechanism of Action

This ingredient exerts its benefits by attracting and binding water molecules, thereby boosting skin and hair hydration and mitigating dryness. As a hydrolyzed collagen derivative, it supplies essential amino acid building blocks that can support existing collagen and elastin fibers. Furthermore, it may stimulate fibroblasts to encourage the natural production of new collagen, elastin, and hyaluronic acid, while also forming a fine film to impart a noticeably smoother feel and improved appearance.
