Ulva Lactuca (Sea Lettuce) Extract

What is Ulva Lactuca (Sea Lettuce) Extract?

Ulva Lactuca Extract derives from Ulva lactuca, a green macroalga commonly called sea lettuce, abundant in temperate coastal waters. This marine plant yields an extract containing polysaccharides, proteins, lipids, vitamins, and minerals through solvent extraction or other processing methods. In cosmetics, it belongs to the skin conditioning and protecting categories, appearing in creams, lotions, masks, and serums. It works by creating a lightweight film on the skin surface to lock in hydration and defend against dehydration and external elements. Its natural emollient qualities help enhance skin's suppleness, while components like sulfated polysaccharides support moisture retention without greasiness. Widely used in natural and marine-derived formulations for everyday skincare routines.
