Laminaria Japonica Extract

A seaweed extract containing minerals, polysaccharides, and phenols, used in cosmetics for hydrating and antioxidant claims. It is generally well tolerated, though those with iodine sensitivity should be cautious, as seaweed-derived ingredients contain naturally occurring iodine.

Cosmetic information for general education, not medical advice. A verdict is a reading of the published evidence, never a guarantee for your skin: any ingredient can irritate someone, so patch test new products and see a professional if you react. Concern is graded on cited evidence, never on hazard-score lists. See how we score.
