Key Information

Why Watch: It is important to tell the difference between a standard eczema flare-up and an infection. This video explains how to spot the "golden crusts" and other warning signs that mean you need urgent medical attention.

The Mechanism: Eczema causes a "leaky" skin barrier. Sometimes, bacteria can get through this barrier and cause an infection. When this happens, a standard flare-up changes its character and needs a different approach.

Spotting the Signs

A standard flare-up is red, dry, and itchy (inflammation). An infection looks and feels different. 

Look out for these key signs:

• Weeping fluid
• Golden-yellow crusts
• Pus spots
• Feeling unwell

What to Do Next

If you notice weeping fluid, yellow crusts, pus spots, or feel unwell, please contact us. Infected eczema usually needs antibiotics to clear the bacteria. While steroid creams are excellent for inflammation, they cannot clear a bacterial infection on their own.
