A
  • Action plan

    A personalized document, created with your healthcare team, that outlines your doctor’s instructions for how to manage your atopic dermatitis, from basic skin care to how to respond to flares.

  • Allergen

    A typically harmless substance that causes a response by the immune system. Examples of allergens include pollen, dust mites, animal dander, and mold.

  • Allergy

    A chronic condition characterized by an unusual reaction by the immune system to a typically harmless substance, called an allergen.

  • Atopic dermatitis

    A chronic skin disease characterized by skin inflammation and itch. Atopic dermatitis is the most common type of eczema. Scratching the skin results in redness, swelling, cracking, oozing, crusting, and scaling. Atopic dermatitis is not contagious. Also called atopic eczema.

B
  • Bacteria

C
  • Chronic

    Lasting for a long time or occurring over and over for a long time.

  • Crusting

    Dried fluid on the surface of the skin.

D
  • Dermatitis

F
  • Flare-up

    The sudden worsening of symptoms of a disease, for example, atopic dermatitis.

I
  • Immune Cells

    Cells that help the immune system protect your body from infections. There are many types of immune cells; for example, white blood cells (that include T cells) help the body fight diseases.

  • Immune Response

    Your body’s response to a substance that the immune cells recognize as foreign.

  • Immune System

    The defense system that protects your body against harmful substances and invaders such as bacteria and viruses. Immune system is made up of many different cell types and organs.

  • Immunological Disease

    A disease that starts when the immune system fails to function as usual. Immunological diseases include allergy, asthma, atopic dermatitis (atopic eczema), and autoimmune diseases.

  • Infection

    Invasion of the body by harmful organisms, such as bacteria, viruses, or fungi.

  • Inflammation

    The body’s response to damage caused by bacteria, harmful substances, high temperature, or other factors. The damaged cells produce chemical signals that attract white blood cells, causing swelling in the surrounding tissues. Inflammation can lead to pain, itchiness, and redness.

  • Irritant

    A substance that causes irritation but does not cause an immune response. Examples of irritants include wool, synthetic fibers, soaps, detergents, some cosmetics, chlorine, dust, sand, and cigarette smoke.

  • Itch

  • Self-compassion

    Treating yourself with the same kindness you would treat somebody else who is going through a difficult time.

  • Self-conscious

    Being highly or uncomfortably aware of yourself.

  • Skin Cells

    Different types of cells that perform special functions. Skin cells produce substances that defend the body against invading organisms. Immune cells are a type of skin cell.

  • Steroid

    Medications that decrease inflammation and modulate the immune system. Steroid creams and ointments are frequently used to treat atopic dermatitis.

  • Stress

    The way you respond to difficult circumstances, for example, work, school, and life changes.

  • Subcutaneous

    Under the skin.

  • Swelling

    A local increase in the size of a body part caused by accumulation of liquid in the tissue.

T
  • T Helper Cells

    Type of white cell that helps protect the body from infections by sending chemical signals that influence how other immune cells act.

  • Triggers

    Something that can make your atopic dermatitis worse. Examples of triggers include dry skin, irritants, stress, hot and cold temperature, sweating, infection, allergens, and hormones.

V
  • Viruses

    Small and very simple organisms that can infect cells and cause diseases. Viruses cannot grow outside of infected cells and are not considered to be living.
