Crithmum Maritimum (Sea Fennel) Extract

What is Crithmum Maritimum (Sea Fennel) Extract?

Crithmum Maritimum Extract comes from the leaves and stems of the sea fennel plant, a succulent coastal halophyte native to Mediterranean and Atlantic shores. This botanical thrives in harsh, salty environments, yielding an extract rich in polyphenols, flavonoids, vitamins like C, and minerals. In cosmetics, it falls under plant-derived actives used in serums, creams, and toners. It works by forming a lightweight film on the skin to lock in moisture, enhance texture, and impart a subtle tightening sensation through mild astringent and humectant properties. Its antioxidant components help neutralize environmental stressors, supporting overall skin resilience without heaviness.
