The Bladderwrack Breakdown: Why It’s So Special Bringing to light the amazing benefits of the ancient seaweed

We decided to have a little fun while discussing bladderwrack, one of Sea Calm Skin’s star ingredients commonly associated with the symptoms of eczema and psoriasis. Our mission at Sea Calm Skin is to improve quality of life, so we figured, “Why not throw a little empathy bladderwrack’s way with a therapy session of its own?” (Below are the session notes.)

Bladderwrack, don’t be a sadsack — you’ve got a lot going for you.

Bladderwrack, we feel you; not the most flattering name. It sounds more like a condition that you’d hear mentioned in an ad about urinary incontinence than a seaweed used to help soothe dry skin and other symptoms of eczema and psoriasis. In bladderwrack’s defense, the name makes complete sense. This seaweed, found along the shores of the North and Baltic seas and the U.S.’s northern Atlantic and Pacific coastlines, has distinctive sacs or “bladders” along the midrib branches. Some call it rock weed, red fucus, and black tang, but marine scientists prefer fucus vesiculosus.

Your defense mechanisms make you a real survivor.

Not only do the pods act as packing peanuts from tidal flux — cushioning the thallus (aka plant body) from being smashed up against the rocks and other underwater objects — these gel bubbles double as floatation devices to give blades a lift in gathering more sunlight. Conversely, when low tide exposes the seaweed to intense sunlight, the pods shelter the plant from withering. Bladderwrack’s protective nature is passed on to people living with eczema and psoriasis who incorporate it into topical treatments. Packed with antioxidants, the unique seaweed helps soothe the skin. We understand that you used to be legendary…we still believe in you.

While the rise in popularity in contemporary naturopathic circles, bladderwrack is no newcomer to the world of herbal medicine. In fact, ancient folklore revered it as the herb of protection for dangerous sea voyages and the Irish have been using it for centuries in hydrotherapy treatments. The Romans used it to treat sore joints and tuberculosis, while the Greek physician, Pedanius Dioscorides, and author of famed herbal medicine encyclopedia De Materia Medica, claimed it battled inflammation and gout. Bladderwrack’s high concentration of iodine and other minerals such as zinc, magnesium and potassium are now used in supplements to remedy everything from heartburn to hypothyroidism, diabetes to obesity. Not only do the trace minerals help to soothe dry skin, one Japan study found it also possessed anti-aging benefits.

Cheer up. You’ll have your day in the sun...

This greenish-brown seaweed contains fucoxanthin, a plant pigment chock full of healthy antioxidants, which makes it darker than many other types of seaweed. This helps the plant capture a broader spectrum of light, use more energy from the sun, and photosynthesis a breeze.

...especially when people realize all you can do for symptoms commonly associated with eczema and psoriasis.

But fucoxanthin can’t take all the credit for bladderwrack’s success in treating skin conditions. It also contains fucoidan, a powerful anti-inflammatory being studied for a broad range of applications. Sea Calm Skin incorporates this famous brown seaweed into the MarineClear TechnologyTM to help mitigate redness associated with psoriasis flare-ups, and ward off future episodes.

You have a lot of attractive qualities.

It’s important to keep in mind that bladderwrack isn’t just any seaweed. It’s a dual-action dynamo. Seaweed lives symbiotically with bacteria, which is used for plant nutrition. But some bacteria are actually harmful. Bladderwrack has an amazing knack for differentiating, able to attract the beneficial bacteria while simultaneously fighting off those which prove harmful. Not only that, it was able to adapt to remain effective even when subjected to total darkness and significant changes in temperatures. Could this adaptive nature hold the key to its effectiveness in keeping the skin healthy and balanced? Time will tell.

And you make this world a better place.

Harvesting bladderwrack is beneficial for the environment. The plant merely anchors itself to the ground, it’s not rooted. This is important because it doesn’t deplete the earth of nutrients, rather gets it RDA from surrounding waters. During which, it also acts as a filter, absorbing pollutants and “fixing them.” For instance, bladderwrack transforms water-polluting nitrogen used in many agricultural fertilizers and transforms it into a molecular form that can be used by living organisms to process proteins that help them survive and thrive.

That’s why we’d like to continue cultivating a healthy relationship.

This session with bladderwrack isn’t the only hand holding we do at Sea Calm Skin. The organic bladderwrack used in Sea Calm Skin is hand-harvested off the coast of Ireland. We treat it with TLC because it’s such an important member of the family created to soothe the frustrating symptoms of eczema and psoriasis. For instance, Sea Calm Skin Soothing Bath Soak recreates the essence of hydrotherapy in Ireland and delivers it directly to your doorstep. This relaxing soak, imbued with all of bladderwrack’s essential minerals and amino acids, cultivates a healthier relationship with your skin—and a happier you.
