Laminaria Digitata Extract

Laminaria digitata is a marine plant extract rich in nutrients and compounds that help to soothe signs of reddened, irritated skin and mitigate signs of sun damage.

Also known as sea kelp and brown seaweed, Laminaria digitata contains skin-soothing beta-glucan, polyphenolic antioxidants known as phlorotannins (these help brown seaweed withstand UV exposure) and phloroglucinol, which are responsible for this extract’s skin-calming benefit. These and other antioxidants help support skin’s firm look and feel, making Laminaria digitata a great option to see in anti-ageing products.

Usage levels of Laminaria digitata extract range from 0.0001%–5%, depending on formulary needs and desired claims. It is among the edible types of seaweed and several toxicology tests have consistently shown this extract is non-irritating when applied to skin.
