What it is
Himanthalia Elongata Extract is obtained from a brown alga commonly called sea spaghetti, which is harvested along Atlantic coasts and is also eaten as a vegetable. In cosmetic formulas it contributes polysaccharides and minerals that help condition and hydrate the skin, and it is included for its antioxidant character. In sunscreens it appears as a supporting botanical rather than as a UV filter.
Safety & warnings
Marine algal extracts of this type are generally well tolerated in cosmetic use. As with any botanical extract, sensitive individuals may occasionally react, and people with known seaweed or iodine sensitivities should be mindful. It is not an oil and is not considered comedogenic.
Origin & sourcing
Natural; a water or solvent extract prepared from the thallus of the brown seaweed Himanthalia elongata.
