Laminaria digitata, also known as oarweed or kelp, is a brown seaweed with a dark or golden appearance. It is rich in skin-beneficial ingredients, including vitamins A, B, C, and E, minerals, amino acids, and other phytochemicals. The extract is a powder derived from the dried, ground thallus of the alga.

Laminaria digitata extract functions as a conditioning agent, antioxidant, humectant, pigment, and texture enhancer. It also has sebum-control, soothing, and anti-cellulite properties. It is used in deeply hydrating skincare formulations and hair products targeting dryness and brittleness. Laminaria digitata extract is an ideal addition to anti-aging formulations for sensitive skin.
