Brown seaweed such as wakame and kelp have high concentrations of a pigment called fucoxanthin, which is unique to brown seaweed. Fucoidan has an anti-aging effect and has been found to improve skin elasticity and collagen production.
Brown algae also contains laminaria, a polysaccharide that improves circulation and the appearance of the skin, making it smoother, more even toned and radiant.
Applying seaweed topically delivers essential nutrients such as zinc, selenium and vitamins A and C, directly to the skin. These nutrients are all needed to support collagen and elastin production, which improves skin firmness and tone.
These remarkable marine plants are also rich in a vast array of antioxidants including carotenoids, polyphenols, and asthaxanthin, needed to protect skin cells against environmental aggressors such as UV radiation and pollution. The carotenoids and polyphenols also absorb UV rays to help deflect the damaging effects of the sun.
Polysaccharides found in seaweed such as L-fucose have anti-inflammatory properties and provide a super moisturising action on the skin.
Using a moisturizer like Zk’in  rejuvenating moisturizer which contains an organic brown seaweed extract is an excellent way to fight premature skin ageing and improve the look and feel of your skin.
