Keratinocytes become less tightly held together. This is what happens when you have eczema. A reaction in the epidermis (outer layer of skin) causes this condition. The result is a weakened skin that becomes vulnerable to many external irritants including water. Once eczema is set in motion and your skin is reacting to an allergen, you may find that the reactions you encounter may be as mild as a small rash, progressing up to infernal as in a severe eczema outbreak.

There are a number of things you can do at home to help you avoid eczema flare-ups. You will want to stay away from heavily perfumed and colored soaps, shampoos and moisturizers. In place of soaps and shampoos, you can try to use a shower gel. Some eczema sufferers are finding shower gels an innovative way of getting clean without all of the side effects that soap gives.

When you choose cosmetics, use the ones with the fewest ingredients. Many ingredients contained in cosmetics will say "natural, " but that does not necessarily make them good for you. Even natural ingredients depending on what they are and what they do can work against the proper function of your skin.

Products that are hypoallergenic (does not cause allergies), non comedegenic (does not block pores, ) and also include anti-inflammatories are better choices for you skin's health.

So how should you use make up when you have eczema?

First, never use make up when you are having a flare up. All cosmetics have offensive ingredients in them; it is only a question of which ones are better for you. This is where you will have to become familiar with which ingredients are apt to set the itch scratch cycle at work on your skin. But you will always want to avoid lanolin which is a common ingredient in many cosmetic applications.

If you are not having a flare up, then you begin by moisturizing your face. The parts that have eczema should be included. When applying the foundation, the goal is to neutralize the redness, not just cover it up. The experts suggest that using a green shade of foundation will perform this for you, giving you an even looking appearance. Do not use formulations that are promoted to fight aging or control oily skin. They will have ingredients that you want to avoid.

Also when choosing a make up, look for formulas that come off with water.
