Causes, Types and Treatment of Eczema on the Hands Face Feet and Scalp

" Eczema refers to an inflamed skin condition. Symptoms include skin itch, crusting, redness, and clear oozing. There are several possible causes ranging from an allergic reaction to something that comes in contact with the skin to allergy where the immune system over reacts to a substance  (food, plant animal, chemicals, allergen in the air such as pollen) . As the skin becomes inflamed it produces a substance which causes itch.  Itching and scratching can worsen the condition and introduce bacterial infection. The most common type in children is atopic dermatitis, which refers to an allergic reaction. Treatment involves identification of the underlying cause, removal of potential triggers such as an allergen, bath soap or laundry detergents, and the use of medications that can address inflammation or allergic response. The condition is not contagious."  



Eczema is a type of dermatitis which refers to inflamed or swollen skin. It can appear anywhere on the body and can be found on children and adults.  It is used to refer to a broad range of skin problems that are usually characterized by skin crusts, itch and pus.

Eczema Treatment


As mentioned, there are many causes for this condition, with treatment based on identification of the trigger.  Once this trigger is diagnosed, a specific treatment plan can begin to address the problem, including avoidance of any allergens, such as changing laundry products or soaps.

If food is suspected, the eczema diet and can be changed to an elimination diet where the patient limits the diet to one protein and carb, such as chicken and rice. If patient improves on simplified diet, ingredients are added back in until problem reoccurs.  Once this happens, you can identify the problem food component.

Seborrheic eczema is treated with over the counter dandruff shampoo containing coal tar, salicylic acid, zinc or ketoconzaole, or selenium.  Lotions containing similar ingredients can be helpful when treating other areas of the body.

If the Doctor cannot identify the underlying cause, there are treatment approaches available that can help.  Basic treatment approaches include:

  • Corticosteroid cream (over the counter or prescription). Chronic cases may require an oral corticosteroid for use over a short period of time.
  • Injection antibiotics for infection
  • Antihistamines for allergic skin reactions
During and after recovery, a natural homeopathic skin cream such as ClearSkin-E may be of some benefit for supporting natural skin immunity and to support skin health.
