Laminaria saccharina, also known as sugar kelp, is a species of brown algae that can be found in several oceans throughout the world. In skin care, Laminaria saccharina extract is used as a moisturizing and anti-inflammation additive because of its hydrating and soothing characteristics.
Laminaria saccharina extract is an excellent moisturizer because it contains alginates, which are hydrophilic (water-loving) polysaccharides that bind water and create a protective film on the surface of skin. Laminarin is another polysaccharide found in Laminaria saccharina extract that is thought to benefit the skin by clearing pores and balancing oil production. It also has antibacterial and antiviral properties. These characteristics make Laminaria saccharina extract ideal for those with acne prone skin.
