What is Eczema

Eczema simply means “inflamed skin”. Skin can become inflamed for a number of reasons, but the big three reasons are: Contact, Atopic, and Irritant. Part of the eczema confusion stems from the fact that ALL eczemas look very similar - chapped, red, scaly skin. Another item that all eczemas share is their therapy. Proper hydration is the absolute cornerstone for any regimen aimed at calming all eczemas. A well moisturized skin barrier is less susceptible to environmental allergens of all kinds and will begin the recovery process. Sometimes an anti- inflammatory prescriptive may be required in addition to a hydrating barrier repair.

Contact Eczema (CE) can be caused by a dizzying number of natural as well as household and workplace chemicals. The most infamous form of contact dermatitis is poison ivy, so called “rhus dermatitis” for the rhus allergen found within this plant. The onset of CE can evolve over time. The immune system is exposed to a certain allergen several times until one day our body triggers an allergic response that can persist for a lifetime.

Certain clues for a contact dermatitis include a bilateral (both sides) rash. The most common locations affected are the neck and eyelids. Interestingly, these are areas most commonly exposed to foreign chemicals (usually from fingers-to-face contact). Most chemicals able to provoke CE are small molecules that can penetrate human skin. Your immune system recognizes a foreign substance (“antigen”) and then mounts an immune response to it, resulting in itchy, scaling skin. Common CE allergens are:

  • Nickel (and nickel-plated objects)
  • Fragrance
  • Neosporin
  • Propylene glycol (a common preservative)

If you’ve been experiencing a recurrent rash that is intermittently worse, patch testing can be performed to determine the offending botanical, metal, or chemical. Short-term therapy can be given to quell an active rash, but the best solution is to avoid the offending chemical altogether.

Atopic Eczema (AE) is usually an inherited condition that stems from a general sensitivity to allergens. For example, even a slight increase in dust or pollen counts can trigger an inflammatory cascade that will leave skin red and itchy. There is not a specific allergen identified as in CE, but rather a general hypersensitivity to environmental triggers. If you were to place individuals with AE in a plastic bubble, protected from the environment, their skin would clear almost entirely. Common triggers for atopic eczema include:

  • Heat and sweating
  • Pet fur and dander
  • Wool and synthetic fibers like nylon
  • Tobacco smoke
  • Fragrances or colorants in shampoos, detergents, soaps, and moisturizers

Irritant Eczema (IE) is the simplest form of eczema caused by rapid dehydration. Chapped lips and cheeks from windburn is perhaps the most common manifestation of this eczema. Any environmental feature that can rapidly desiccate (dry) skin is considered an irritant. Even water within a wet bathing suit can evoke red, itchy skin, and can be considered an irritant. Some mechanical forces can trigger an irritant dermatitis as well. Straps and belts are notorious induces of irritant eczema. Removal of the irritant is, of course, the first step toward improving the resultant inflammation.

As discussed above, the key to addressing any eczema is to (1) remove any contributors to the eczema and (2) re-hydrate the skin so that it remains protected.
