Laminaria Digitata Extract for Skin

What Is Laminaria Digitata Extract?

Laminaria digitata extract is derived from the Laminaria digitata algae (seaweed). This seaweed is very large, with broad, brown leaves that can grow up to 4 meters in length. It’s also commonly called “oarweed” due to the long, oar-like appearance of its leaves.

This seaweed grows throughout the Atlantic Ocean and is common around America, the UK, Russia, France, Greenland, and more. It has been used for a wide variety of purposes. Historically, it was broken down and used as a fertilizer due to its nutritive properties, and in the 18th century, it was burned to create potash, which is a type of salt used to make glass.

The use of Laminaria digitata extract in skincare is more common today, though. It’s mostly used in the cosmetics industry. Laminaria digitata extract is derived by processing the leaves of this seaweed to concentrate its beneficial compounds.
