If you’ve ever run into seaweed or similar marine plant life at the beach, you know it’s not very glamorous stuff. Cold and slimy are the words that come to mind. However, marine plants like seaweed (also known as algae and kelp) are rich in minerals and antioxidants, making them potent anti-aging ingredients in natural skincare. Seaweed contains nutrients like beta-carotene, potassium, iodine and zinc. You’ll also find a host of essential amino acids and Vitamins A, B, C and E in most seaweed, too. Seaweed takes nutrients directly from the ocean, making them a more potent source for antioxidants than many land plants.
There are many types of seaweed, and in skincare you may see it listed as algae or kelp or even by the type used. Brown, red, green and blue seaweed are commonly found in skincare. Brown seaweed can help soften and moisturize skin while stimulating collagen production. Green seaweeds are better for astringent purposes, while red seaweeds are high in beta-carotene and other antioxidants. Some sea algae even has skin lightening abilities, which is why you’ll see it included in some brightening serums. Overall, seaweed is a wonderful way to naturally boost antioxidant levels in skin, protecting it from UV and free radical damage while also hydrating and calming the skin. It tightens and tones skin, increasing moisture levels and elasticity. Think of this reparative ingredient as kale for your face, and make use of it for healthy, glowing skin.
