Seaweed In Skin Care Products

What do you think of when you think of seaweed? I think of plant life that has washed ashore and is not so sweet smelling but did you know that seaweed contains natural anti-aging properties. Seaweed in skin care products  can help improve the suppleness and elasticity of skin.

Do you like going to the beach and soaking in the sea water. Do you ever wonder why your skin feels softer and small cuts and abrasions seem to heal faster after spending a day at the beach? People have soaked in sea water for thousands of years. Actually, the term “Thalassotherapy” stems from the Greek word for sea, thalassos. It  refers to the usage of sea water for therapeutic purposes based on the belief that immersion in sea water revitalizes, heals, and cleanses the system.

Seaweed grows in the ocean and is rich in antioxidants, fiber, and Omega-3 fatty acids. It also has a fair amount of iodine.

There are many different types of seaweeds which are broken down into categories by color.

  • Brown: Bown seaweed is found in the upper middle section of the ocean and provides essential fatty acids needed for maintaining skin barrier. Most people have heard of kelp, which is also another term for brown algae. Brown algae is the most commonly used type of algae in skincare products, it grows in colder waters and is mostly harvested in the Northern Hemisphere. Brown seaweed is rich in vitamins, minerals, and amino acids. This type of seaweed is hydrating and nourishing, it also has a large level of antioxidants.
  • Red:  This type of seaweed is found in the deepest part of the ocean. Red seaweed can  help with hydration,  nourishment, UV protection and add antioxidants to the skin. It can also help repair damaged  skin. One type of red algae also commonly referred to in skin care as rhodophyta seaweed, contains high quantities of sulfated polysaccharides (carrageenan), peptides, carotenoids, and fatty acids. Together these components may contribute towards red algae’s antioxidant property.
  • Blue/Green: This type of seaweed adds hydration to the skin. some species have been shown to increase collagen production. Blue/Green seaweed is also nourishing and can help protect the skin barrier.

As you can see, seaweed can stimulate the renewal of skin cells and tone while being naturally moisturising. It  can also help with the appearance of fine lines and wrinkles resulting in brighter, younger and fresher looking skin.
