Ingredients: Seaweed

Extracts made from the many different types of seaweed are also readily available as effective Marine Ingredients. These aquatic polymers are excellent moisturisers. They can also be the backbone of skin benefiting face masks. Marine biopolymers often combine alginate powder blend and diatomaceous earth with alginates and calcium salts to make a quick setting face mask base. This base can be used to carry a variety of anhydrous active ingredients.

Seaweed and the Human Skin

Not only can seawater provide a balanced way to supplement minerals to human cells, it also provides a nutrient-rich growing environment for seaweed. As marine plants grow in this amazing mineral medium, they absorb and concentrate various nutrients also beneficial to the human body.

The wealth of essential vitamins, minerals, amino acids and antioxidants in seaweed helps in keeping the skin revitalized, moisturized, and youthful. These elements guard the skin against the harmful effects of environmental pollutants and helps to slow down the skin’s ageing process. 
Clinical research has made it evident that seaweed extracts contain anti-ageing properties and are a useful ingredient in the manufacturing of skin health products. 
The anti-inflammatory properties present in seaweed are useful in treating skin rashes and wounds. The phytonutrients elevate blood flow and bring a healthy glow to the face. Seaweed wraps detoxify and cleanse the skin by expelling toxins out of the pores.

Biotechnology Research  

During the past 40 years, techniques used to preserve seaweed post-harvest - including the process of nutrient extraction - have become extremely sophisti­cated. Once seaweeds have been harvested, they must be preserved in a way that respects the integrity of the raw material. If heat or chemicals are used to preserve seaweed, they can damage the potency of nutrients - including important peptides, vitamins, enzymes, fatty acids, antioxidants and complex sugars. Freeze-drying has proven to be the best way to preserve seaweed’s potency because, instead of using heat or chemicals, a cold process removes the water. All that is left after freeze-drying is the dry matter, including nearly 100% of the original concentration of biological actives.

Perfectly preserved algae can then be used to create high-quality, potent ingredients, otherwise known as seaweed extracts. State-of-the-art extraction and filtration methods can isolate and extract very specific molecules. These molecules can then be concentrated into an ideal potency to help balance various skin conditions. 

Seaweeds can be grown via high sea farming, in which seaweed spores are attached to ropes. The ropes are put out to sea in a protected area where the water is very pure and stable. Once the seaweed reaches maturity, it can be cut, freeze-dried and used for ingredients. This method allows seaweed to be grown in a pure, consistent environment that is also incredibly sustainable.

These seaweeds can be grown specifically for skin health use, reducing the need to harvest from the wild and reducing human impact to sensitive marine areas. Undaria pinnatifida is one seaweed that is grown this way for use in cosmeceutical skin health preparations. Extracts of Undaria pinnatifida help to improve the condition of the extracellular matrix, or dermal network of collagen, elastin and hyaluronic acid that keep the skin dense and plump while circulating water throughout the epidermis.
