Impetigo in adults

Impetigo is a contagious superficial skin infection causing honey-coloured crusts, and although commonest in children it readily affects adults, especially on broken skin.

Key points

What matters most, at a glance.

The essentials in plain English - symptoms, when to seek help, who to see and what treatment looks like.

  • Golden-crusted sores, often around the nose and mouth or on damaged skin

  • Highly contagious: avoid sharing towels and stay off work until lesions crust over with treatment

  • Usually treated with antiseptic or antibiotic cream; widespread cases need tablets

  • Specialist: a consultant dermatologist for recurrent impetigo or when an underlying skin disease is suspected

Understanding it

About Impetigo in adults, and what to do next.

Impetigo is a surface infection with Staphylococcus aureus or Streptococcus pyogenes that erodes the very top layer of skin, leaving raw patches that ooze and dry into distinctive honey-coloured crusts. In adults it typically takes hold where the skin barrier is already broken, in eczema, after shaving cuts, insect bites or cold sores, and it spreads easily by touch.

Localised impetigo responds to hydrogen peroxide or antibiotic creams, while more extensive infection needs oral antibiotics; hygiene measures protect the household during treatment. Recurrent episodes suggest staphylococcal carriage in the nose or an untreated underlying skin condition, both fixable. Most people start with their GP, who can refer to a consultant dermatologist. In many parts of the UK, routine NHS referrals for this kind of problem currently take 20-45+ weeks depending on where you live, whereas an initial appointment with a private consultant is typically available within around two weeks.

Frequently asked

Common questions about Impetigo in adults.

Quick, plain-English answers to what people ask us most.

  • What does Impetigo in adults mean?

    Impetigo in adults is a health condition that affects how part of the body functions, and can range in severity from mild to significant depending on the individual. A clinician can assess your specific situation and explain what it means for you. Understanding the basics helps you ask the right questions at your appointment.

  • What leads to impetigo in adults?

    There are usually several contributing factors behind impetigo in adults, and it's not always possible to pin down a single cause without proper assessment. Your doctor will consider your symptoms, history, and any relevant investigations to build a clearer picture. This helps make sure treatment is targeted appropriately.

  • What are the symptoms of impetigo in adults?

    Symptoms can vary from mild and barely noticeable to more significant and disruptive, depending on severity and individual factors. Common features often include changes that affect comfort, function, or general wellbeing in the affected area or system. If you're experiencing symptoms that concern you, it's worth having them assessed rather than guessing.

  • How worried should I be about impetigo in adults?

    Most cases can be managed effectively once properly assessed and treated, though how serious it is depends on individual circumstances and how early it's picked up. Getting a professional opinion helps rule out anything more concerning and puts your mind at ease either way. Don't hesitate to seek advice if something feels wrong.

  • Is impetigo in adults hereditary or genetic?

    Some cases have a genetic or family component, while others are linked more to lifestyle, environment, or other health conditions. Having a family history may increase your risk slightly, but it doesn't mean you'll definitely develop it. A clinician can advise whether genetic factors seem relevant in your particular case.

  • Can impetigo in adults be treated or reversed?

    Treatment can often reduce symptoms significantly and, in some cases, resolve the underlying problem entirely, though this isn't guaranteed for everyone. Prevention strategies, where they exist, usually focus on managing risk factors and general health. A tailored discussion with your doctor will give you the clearest picture for your circumstances.

  • How is impetigo in adults treated?

    Treatment options range from conservative measures such as lifestyle changes, medication, or physiotherapy through to more involved interventions in more severe or persistent cases. The right approach depends on the underlying cause, severity, and how it's affecting you. Your specialist will talk through the pros and cons of each option that's relevant to you.

  • What is the typical recovery time for impetigo in adults?

    Some people recover within a matter of weeks, while others find it becomes a longer-term or recurring issue that needs ongoing management. Following your treatment plan closely tends to support the best possible recovery. Ask your specialist for a realistic timeline based on your own results and progress.

  • When is a specialist opinion or surgery needed for impetigo in adults?

    A specialist opinion is generally recommended if symptoms persist despite initial treatment, if they're severe, or if there's uncertainty about the diagnosis. Surgery or more invasive treatment is usually reserved for cases where conservative measures haven't worked. Your GP can refer you on if they feel a specialist review would be helpful.

  • When is it worth getting impetigo in adults checked by a specialist?

    See a doctor if symptoms are persistent, worsening, or affecting your daily life, or sooner if you have any red-flag symptoms your GP has warned you about. Waiting times through the NHS often run to 20-45+ weeks for a routine referral, whereas a private specialist can usually see you within roughly 2 weeks.
