How Bacteria Affect Eczema – And How to Fight It
If you suffer from eczema, you’ve probably noticed that sometimes your skin gets redder, itchier, or even starts to ooze. This might not just be from your eczema flaring up on its own — bacteria could be playing a major role.
Let’s break down how bacteria affect eczema and what you can do to fight back and protect your skin.
The Bacteria Behind Eczema Flare-Ups
​
Our skin is home to millions of bacteria, many of which are harmless or even helpful. But in people with eczema, the skin barrier is weakened, which makes it easier for harmful bacteria to grow.
​
One of the main culprits is a bacteria called Staphylococcus aureus (or Staph for short). Around 9 out of 10 people with eczema have large amounts of Staph on their skin, especially during a flare-up.
This bacteria can:
​
-
Release toxins that irritate the skin
-
Increase itching and redness
-
Make eczema symptoms last longer
-
Lead to skin infections if not treated
​​

Signs That Bacteria Might Be Making Your Eczema Worse
​
Not sure if bacteria are part of the problem? Here are some common signs:
-
Skin is hot, red, or swollen
-
Pus-filled bumps or blisters
-
Yellow crusts or oozing
-
Rapid increase in itching or discomfort
-
Fever or feeling unwell (in serious infections)
If you notice these signs, especially with worsening eczema, it’s important to take action.
How to Fight Bacteria on Eczema-Prone Skin
Here are some ways to protect your skin and keep harmful bacteria under control:
1. Gentle Cleansing
​Use a fragrance-free, non-soap cleanser daily to wash away bacteria without irritating the skin. Avoid hot water and rough scrubbing — this can make things worse.
​
​
2. Bleach Baths
​A weak bleach bath (using Milton Sterilising solution in bathwater) a few times a week can help reduce bacteria levels. For an adult-sized bath, add about 125ml (half a cup) of Milton Sterilising Fluid and rinse off in shower after.
​
​
3. Antibiotic Creams or Medication
​If your skin is infected, a doctor may prescribe an antibiotic cream or tablets. Never ignore signs of infection — treating it early prevents it from spreading.
​
​
4. Moisturise, Moisturise, Moisturise!
​Dry skin cracks easily, giving bacteria more places to enter. Use eczema-friendly moisturisers with ceramides, shea butter, or colloidal oatmeal several times a day, especially after washing.
​
​
5. Stop the Scratch
Scratching spreads bacteria and causes more damage. Try wearing cotton gloves at night, using cool compresses, or applying anti-itch creams.
​
6. Boost Your Skin’s Defence from the Inside
​Eat a skin-friendly diet rich in omega-3s, zinc, vitamin D, and antioxidants. Some people also find probiotics help their skin by balancing the gut and immune system — although results can vary.
Final Thoughts
Eczema doesn’t just come from inside the body — it’s also affected by what’s on your skin. Harmful bacteria like Staphylococcus aureus can make flare-ups worse and harder to treat.
The good news is, with the right routine, you can fight bacteria and keep your eczema under control. Cleanse gently, moisturise daily, and talk to a healthcare provider if you suspect infection.​​
