Eczema causes include…

a. Contact dermatitis

From…

  • Allergens in skincare and makeup;
  • Clothing, jewelry, eyeglasses, accessories;
  • Phone and computer materials and protective cases;
  • Flowers, plants, and fruits;
  • Insecticides, dishwashing liquids, laundry detergents, house cleaning solutions;
  • Airborne allergens from perfumes, room sprays, even vaping.

There are many more common contact allergens than you might think. This is why a patch test is normally done if eczema is suspected. For more on common allergens, check out our popular Allergen-Not An Allergen tab. For products free of all or most common contact allergens, check out VMVHypoallergenics.com. If you would like customized product recommendations based on your particular patch test results, contact us or drop us a private message on Facebook.

b. Atopic dermatitis:

Atopy means an inherited allergy. It is…

  • …Atopic dermatitis when the target organ is the skin;
  • …Rhinitis if the target is the nasal passage;
  • …Bronchial asthma if the target is the bronchial passages (the lungs).

c. Hereditary or acquired:

Because atopic dermatitis is hereditary, it often starts in infancy or early childhood.

Contact dermatitis, on the other hand, tends to develop later as we become more exposed to allergens in things that we use, touch, and are otherwise exposed to.

d. Nummular eczema…

…is caused by a combination of factors that include:

  • Atopic skin with bacterial contamination;
  • Insect bites;
  • Friction and irritation from rough materials; and/or
  • Allergic contact dermatitis.

These factors make the skin hyperactive, causing the large circular patches that characterize nummular eczema.

e. Seborrheic dermatitis

Also known as skin dandruff of the scalp or face often starts as scales. If irritated or secondarily infected (those opportunistic microbes again!), they can become eczematous.
