Zostera Marina Extract
What is Zostera Marina Extract?
Zostera Marina Extract comes from Zostera marina, or eelgrass, a perennial seagrass species in the Zosteraceae family native to coastal marine environments globally. This botanical ingredient is typically produced by extracting active components like polysaccharides, minerals, and phenolic compounds from the plant's leaves and shoots using water or mild solvents. In cosmetic formulations, it serves primarily as a skin conditioning agent, often found in moisturizers, creams, and serums. It functions by creating a lightweight film on the skin surface to lock in moisture, promote suppleness, and support the skin's barrier. Its marine origin provides emollient properties that help maintain hydration balance, making it suitable for daily skincare routines focused on texture improvement.
