Eczema Q & A

What is eczema?

Eczema — often referred to as atopic dermatitis — is a widespread skin condition that causes symptoms that include:

  • Red or brownish-gray rash or patches
  • Dry, scaly skin
  • Severe itch
  • Thick, cracked skin
  • Raw skin or open sores from scratching


Eczema can develop anywhere on your body. The condition is often diagnosed during childhood and can last through adolescence and adulthood. It’s also possible for adults to have eczema symptoms for the first time later in life.


What causes eczema?

Eczema is linked to a genetic variation that affects your skin’s ability to retain moisture and protect you from bacteria, allergens, and other irritants.

The condition is similar to other atopic diseases, including asthma, hay fever, and food allergies. Exposure to irritants and allergens can trigger all atopic conditions, including eczema. Eczema flare-ups are often triggered by:

  • Animal dander or saliva
  • Dust mites
  • Food allergies
  • Excessive sweat
  • Certain soaps and household cleaning products
  • Viruses like the common cold or the flu


Understanding your eczema triggers can help you manage your condition and prevent symptoms from flaring up.


How is eczema treated?

Dr. Aguirre offers customized treatment plans to control your symptoms. Your plan may include a combination of oral and topical medication, injectable biologic medicine, light therapy, and behavior modifications.

Dr. Aguirre can prescribe corticosteroid ointments or oral anti-inflammatories to reduce inflammation in your skin. If your skin is broken or if it becomes so dry it cracks, she may also prescribe antibiotic creams or oral medicines to fight infection. If your eczema symptoms are resistant to treatments, Dr. Aguirre may prescribe dupilumab, an injectable biologic.

Light therapy can also be helpful in reducing eczema symptoms. When your skin absorbs natural sunlight or controlled doses of UVA and UVB light, it can calm the parts of your immune system that cause your rash.


How can I prevent eczema flare-ups?

Dr. Aguirre gives you personalized advice to prevent flare-ups and reduce their severity. For example, you may benefit from taking cooler showers with gentle soaps and moisturizing your skin at least twice a day. Dr. Aguirre can recommend products for you to try. You should also learn about what triggers your eczema and do your best to avoid those triggers.
