Infected Eczema in Adults

How to recognise infection early, what to do safely at home, and how bleach baths/soaks can help in infection-prone eczema (especially hands).

Eczema weakens the skin barrier. Cracking, scratching, and inflammation create openings that allow bacteria or viruses to enter. This can turn a “normal flare” into infected eczema, which often escalates quickly and may need prescription treatment. (1–4)

This page covers:

  • what infected eczema looks like
  • when to seek urgent care
  • what you can do at home safely
  • how to use dilute bleach baths/soaks as part of an infection-prevention plan (without creating a separate adult bleach page).

Key takeaways

  • Infected eczema often looks different from a standard flare: weeping, crusting, tenderness, rapid spread
  • Honey-coloured crusts suggest impetigo (bacterial infection). (1–4)
  • Rapidly spreading redness, warmth and pain can indicate cellulitis and needs prompt review. (2–4)
  • Painful blisters or sudden severe pain can be an HSV complication (eczema herpeticum) — urgent assessment is important. (3,5)
  • For infection-prone eczema, dilute bleach baths or bleach soaks can reduce bacterial load on the skin as part of a broader plan. (2,6–8)

Why infection is more common in eczema

Eczema is a barrier problem. When the barrier is inflamed and cracked, bacteria (especially Staphylococcus aureus) can overgrow, and viruses can enter through broken skin. (1–4)
Hands are particularly vulnerable because they are exposed to wet work, detergents, sanitiser, friction, and repeated micro-trauma.

1) Bacterial infection: impetigo / infected eczema

What it looks like

Common signs include:

  • weeping or oozing
  • yellow “honey-coloured” crusts
  • pustules or small pus bumps
  • increased redness and swelling
  • tenderness or stinging that is worse than usual
  • flare worsening suddenly rather than gradually. (1–4)

What usually happens next

Mild, localised infection may be treated with prescription topical therapy. More widespread infection may require oral antibiotics, particularly if there is significant crusting, rapid spread, or systemic symptoms. (2–4)

2) Cellulitis (urgent)

Cellulitis is a deeper bacterial infection that can start from cracked eczema, especially on legs or hands.

Seek urgent review if you notice:

  • rapidly spreading redness
  • warmth and swelling
  • increasing pain
  • fever, chills, or feeling unwell
  • red streaking or tender lymph nodes. (2–4)

3) Viral infection: HSV (eczema herpeticum) — urgent red flags

Eczema herpeticum occurs when herpes simplex virus spreads into eczema-affected skin. It is less common but important because it can become severe quickly and needs prompt antiviral treatment. (3,5)

Same-day assessment red flags

  • clusters of painful blisters or punched-out erosions
  • eczema suddenly becoming very painful (pain is a key clue)
  • fever, malaise, or feeling unwell
  • rapid spread across areas of eczema
  • eye involvement (rash near eyes, eye pain, light sensitivity). (3,5)

What you can do at home (safe steps)

If you suspect infection:

Avoid applying harsh antiseptics or essential oils directly to eczema — these often irritate and worsen the barrier.

Bleach baths and bleach soaks (hands/feet)

For adults with infection-prone eczema (recurrent crusting, repeated infected flares, or heavy bacterial colonisation), dilute bleach baths can reduce skin bacteria as part of a broader plan. (2,6–8)

You don’t need a separate adult bleach bath page — we use the same RCH-style dilution logic you already have on Eczema Baths for Children and apply it appropriately.

Full recipe (read first)

Use the detailed eczema bath recipe and safety notes here: 
That page includes the bath oil + pool salt recipe and the optional bleach dilution method we base our advice on.

When bleach soaks are especially useful in adults

Bleach soaks (instead of a full bath) are often practical for:

  • severe hand eczema that keeps cracking and crusting
  • recurrent infected fingertip fissures
  • stubborn foot eczema with fissures (selected cases). (6–8)

How to do a bleach soak for hands (practical)

This is the simplest adult adaptation:

1.Use a clean bucket or container and make up a dilute bleach bath using the same dilution used in Eczema Baths for Children (i.e., the “per 10 L” method). (2,6–8)

2.Use lukewarm water.

3.Soak hands for about 10 minutes. (6–8)

4.Pat dry (don’t rub).

5.Apply your plan: anti-inflammatory to active eczema if prescribed (Medications for Adult Eczema (Steroids, Elidel/Tacrolimus, Crisaborole & Hand Eczema Plans)), then moisturiser generously (Daily Routine for Adult Eczema). (2–4)

Tip: If making 10 L feels too much, you can make a smaller volume and scale the bleach down proportionally — the goal is maintaining the same final dilution. (2,6–8)

When not to do bleach soaks

Avoid bleach baths/soaks and seek review first if you have:

  • rapidly spreading redness, significant warmth/pain
  • fever or systemic symptoms
  • suspected HSV/eczema herpeticum (blisters, severe pain)
  • deep open wounds where soak causes significant burning. (2–5)

Should you rinse afterwards?

Different reputable sources differ on rinse vs no rinse. The most important step either way is moisturising immediately afterwards. (6–8)
If your skin feels dry or stingy after a soak, a brief rinse can be reasonable.

Prevention strategies (reduce infected flares)

Most adults reduce infection frequency by focusing on:

If you get frequent infected flares, it’s worth reviewing whether:

  • eczema is under-treated (leading to scratching and skin breaks), and/or
  • contact dermatitis is keeping the skin inflamed and vulnerable (patch testing can help). (2–4)

When to seek urgent care (checklist)

Seek urgent review if:

  • redness is spreading quickly
  • increasing pain, warmth, swelling
  • fever or feeling unwell
  • pus, significant weeping or extensive crusting
  • painful blisters or sudden severe pain (HSV red flag)
  • rash involves the eyes or you have eye symptoms. (2–5)

FAQs

Does infected eczema always need antibiotics?

Not always. Mild localised infection may be managed with topical therapy, but spreading infection, significant crusting, systemic symptoms, or cellulitis usually needs medical review and often oral antibiotics. (2–4)

Should I stop steroid cream if eczema looks infected?

Not always. Sometimes inflammation still needs treatment while infection is treated — but it depends on severity and the type of infection. If you’re unsure, book review. (2–4)

Can I use bleach soaks for severe hand eczema?

Yes, in selected infection-prone cases. It’s often more practical than a full bath. Use the dilution approach in Eczema Baths for Children and moisturise immediately afterwards. (6–8)

Book an appointment

If you have recurrent infected eczema, crusting/weeping flares, severe hand eczema with fissures, or you’re unsure what you’re seeing, we can assess and create a clear written plan covering:

  • flare control
  • infection prevention (including whether bleach baths/soaks fit your case)
  • when to escalate.
