The Bacteria Living On Your Skin That's Keeping Your Eczema Coming Back — And The Marine Ingredient That Targets It In Day

Six years recommending creams that never worked on my own skin. Then I found the ingredient nobody was talking about.

The cycle most eczema sufferers know too well — flare, treat, settle, repeat.

My Story

"Six years as a dermatology nurse. Recommending creams I was using myself every night. Waking up with blood on my sheets. Hiding my arms at work while prescribing the same steroid cycle to patients."

I know what it feels like to stand in the chemist aisle and reach for the same cream that didn't work last time — because you don't know what else to do. I did it for years, as someone who worked in dermatology and still couldn't find an answer.

What changed everything wasn't a new prescription. It was a single piece of research that made me realise the entire approach I had been trained in was missing half the picture.

Why Eczema Keeps Coming Back

Eczema is not just dry skin. It's often linked to a weakened skin barrier that struggles to protect against irritants and microbes.

One of the most studied microbes in eczema is Staphylococcus aureus. It is found far more frequently on eczema-affected skin than on healthy skin, and is associated with increased inflammation and flare severity.

90%

of eczema-prone skin is colonised by Staph aureus — the bacteria most creams never address

The skin barrier is the wall that keeps bacteria out. Eczema breaks it down — and most creams never help rebuild it.

When the skin barrier is damaged, this bacterium can more easily colonise the surface, producing irritants that further inflame the skin. That inflammation weakens the barrier even more — creating a self-reinforcing cycle.

1
Staph aureus releases toxins that trigger inflammation
2
Inflammation breaks the skin barrier down further
3
A weakened barrier lets more bacteria in
4
The next trigger hits already broken skin, and the flare returns

Steroid creams suppress the inflammation at step one. They don't touch the bacteria. They don't rebuild the barrier. So the cycle resets — every single time.

The Ingredient I Almost Scrolled Past - Sea Moss

I wasn't looking for a natural remedy. I was looking for anything that addressed the bacterial side of eczema without the long-term drawbacks of steroids.

Sea mossChondrus crispus — is a marine plant used in coastal communities for centuries. What researchers found is that its sulfated polysaccharides demonstrate natural antimicrobial activity specifically against Staph aureus, while its mineral content supports the skin barrier repair that keeps bacteria out.

It wasn't coating the problem. It was addressing the environment on the skin that was driving the flares in the first place. Within two days my skin was calmer than it had been in months. By week two I stopped waking up scratching.
