Laminaria Digitata Extract
What is Laminaria Digitata Extract?
Laminaria Digitata Extract derives from Laminaria digitata, a brown alga or kelp species native to the cool waters of the North Atlantic Ocean. This seaweed thrives in intertidal zones and is harvested for its rich composition of polysaccharides such as alginates and fucoidans, along with minerals, amino acids, and trace vitamins. In cosmetics, it falls into the category of marine-derived botanicals commonly featured in moisturizers, creams, serums, and masks. It functions primarily through its humectant and film-forming properties, helping to draw moisture to the skin's surface while creating a lightweight barrier that shields against environmental stressors like dryness and pollutants. Its emollient nature also contributes to smoother texture application in formulations.
