People with dry skin or Eczema tend to get tiny bumps on the arms and legs. These bumps are caused by hair follicles that become clogged with oil and dead skin. When you notice them, apply an acid-based moisturizer. This will help clear pores by removing the outer layer of dead skin cells. Exfoliating with a gentle loofah three to five times a week is also helpful.
Besides exfoliating, a diet containing plenty of fruits, vegetables and lean protein can be beneficial. Occasionally eczema can be caused by food allergies, the most common triggers being wheat, corn and dairy. If after two weeks of exfoliating you don't see any difference, experiment with eliminating these "trigger" foods for two weeks.
