Eczema

If you’re experiencing unexplained skin symptoms, it’s a good idea to speak to a pharmacist or doctor. Dry, itchy and scaly skin may be a sign of eczema.

What is eczema?

Eczema is a condition that affects the skin, causing it to become dry, red, itchy and scaly. In more extreme cases, skin affected by eczema can crack, bleed and weep.

Eczema is very common, particularly amongst children. In the UK, one in five children and one in 12 adults live with eczema.* In many cases, symptoms improve significantly or disappear entirely with age, however it can be a condition that you live with on a long-term basis.

In most cases, treatment involves the application of moisturisers, and medicated creams and ointments. Our pharmacy team can help with product recommendations, visit your local store for advice and shop online.

What causes eczema?

Eczema is not a contagious condition – in other words, you can’t “catch it” from someone who has it, or pass it on yourself.

In most cases, the symptoms of eczema are either caused by underlying factors, such as a genetic susceptibility to dry skin, or by the skin coming into contact with an irritant or allergen. In some cases, it may be a combination of the two.

How and when symptoms arise will depend upon the type of eczema you’re experiencing.

Types of eczema

The most common type of eczema is atopic eczema. This is essentially an allergic condition, caused by the immune system “overreacting” to harmless things in your environment. People with atopic eczema commonly experience other allergic conditions such as hayfever and asthma, and often have family members with allergies.

If you have atopic eczema, you’ll typically experience flare-ups of symptoms after coming into contact with certain triggers. Food allergies are commonly the cause of eczema flare-ups, as are harsh soaps, extreme weather conditions, pollen, and animal fur.

Other types of eczema include:

  • Contact dermatitis – This is where the skin reacts to irritants in the environment, such as harsh chemicals. Contact dermatitis is a common occupational health problem for people who work with irritating substances or materials. If you’ve ever had atopic eczema you will be more susceptible to contact dermatitis.
  • Seborrhoeic dermatitis – This is a type of eczema where symptoms affect areas of the body with numerous sebaceous glands e.g. the face, scalp and chest. One of the key symptoms is dandruff. This type of eczema is thought to be caused by an inflammatory reaction to a specific type of yeast that lives on the skin. Find out more about seborrhoeic dermatitis in our guide here.
  • Discoid eczema – This type of eczema causes circular patches of dry, red and scaly skin to develop. The cause isn’t fully understood, but it can be experienced by people with a history of atopic eczema.
  • Gravitational or varicose eczema - this occurs on your legs when you have poor blood flow.
  • Hand eczema - is one of the most common types of eczema and also referred to as dermatitis - it mainly affects the palms but can also affect other parts of the hand.

Symptoms of atopic eczema

Most people with eczema have the atopic version of the condition. The characteristic symptom of atopic eczema is dry and itchy skin that may also be red, sore and cracked.

Eczema can affect large areas of skin, and most commonly occurs on the hands and fingers, the insides of the elbows, the backs of the knees, and the face and scalp. You will typically have periods where symptoms flare up, followed by periods where symptoms improve.

If your eczema is more severe you might experience:

  • Widespread patches of red, inflamed skin
  • Constant itching
  • Cracking and bleeding
  • Skin infections

An infection can happen if the skin cracks due to extreme dryness or scratching. Signs of an infection include a yellow crust on the skin, fluid oozing from the skin, inflammation and soreness, and generally feeling unwell with a high temperature.

If you think you have a skin infection you should see a doctor as soon as possible. In the meantime, don’t use bandages or cover the eczema.

Treating atopic eczema

If you have atopic eczema, it’s likely that your daily treatment regime will involve two things:

  • Cleaning and moisturising the skin with emollients
  • Applying topical corticosteroids directly to affected areas

Emollients are cleansers and moisturisers that reduce water loss from the skin and help create a protective barrier. Emollients can come as ointments, which contain a lot of oil and are designed for very dry skin, or creams and lotions, which are tailored towards skin that is less dry.

Emollients should be applied across the skin in a large quantity, even when you’re not experiencing eczema symptoms.

Which emollient is best for me?

Adding an emollient to your skincare routine can help to soothe eczema symptoms. These are in the form of creams to be applied to skin when it is dry, oils which can be used when bathing and washes for showering.

  • E45 emollient wash cream – This moisturises and cleans the skin, and does not change the pH balance of dry or itchy skin. It also helps dry skin retain its natural moisture.
  • Dermal 600 bath emollient – Formulated to manage dry skin conditions. This product is a pharmacy medication which means that you will need to answer a few questions when buying online or in pharmacy.
  • Aveeno moisturising cream – Soothes and relieves dry and itchy skin, suitable for those prone to eczema.

It is recommended that you create a balanced and holistic skincare routine when you have eczema. Using products that are specially designed for eczema prone skin can help to manage your condition. This means when bathing or showering that you wash your skin with products suitable for dry skin, and then afterwards moisturise your skin with specially selected products.

What else can I use to treat eczema?

Topical corticosteroids are medicated creams and ointments that can help to soothe the symptoms of an eczema flare-up. Unlike emollients, they should only be applied to affected areas of skin when you’re experiencing symptoms. The steroids in the cream will help to reduce inflammation and irritation.

Another treatment used by people with eczema is antihistamines. These are usually recommended for people who are experiencing severe itching as a result of their eczema. The treatment works by limiting the effects of the allergic reaction that is causing the flare-up.

Avoiding eczema flare-ups

In addition to making sure you’re using the correct treatments, it’s a good idea to make a plan for avoiding your eczema triggers. These are the allergens and irritants that set off your symptoms.

Common triggers include:

  • Soaps and detergents
  • Dusty, damp or mouldy conditions
  • Animal fur
  • Pollen
  • Certain weather conditions (e.g. extreme heat or cold)
  • Food allergies (e.g. peanuts, milk, eggs, wheat)
  • Materials worn next to the skin (e.g. wool)
  • Hormonal changes (e.g. during your period or a pregnancy)
  • Having an infection in the skin

It’s best to try and avoid your triggers altogether, but if you know you might be exposed, make sure you have all the treatment you need to deal with a flare-up.

In addition to avoiding triggers, you should resist the urge to scratch any skin affected by eczema. Scratching can cause damage, worsen your eczema, and make your skin feel even more itchy.
