Dealing with Winter Dryness and Eczema
Winter can be especially challenging for those who suffer from dry skin and eczema. Eczema
occurs when there is an abnormality in the skin's outermost layer, the stratum corneum, which
functions as the skin’s protective barrier. This barrier (the top layer of skin that you can feel
when you touch your skin) is composed of corneocytes and intercellular lipids that help protect
our bodies from external irritants.
However, when this protective barrier is compromised, it can no longer effectively retain
moisture, leading to excessive water loss through the epidermis, which in turn causes the skin
to become dry. Additionally, changes in ion concentrations, such as calcium within the skin
cells, can lead to abnormal thickening of the stratum corneum.
For those who experience dry skin accompanied by eczema, the first question I often ask is
whether they have pets. While pet hair, dander, and saliva can irritate the skin and trigger
allergic reactions, it’s important to note that not everyone with eczema is allergic to pets.
However, for those who are, allergens from pets can exacerbate the condition. In countries like
Australia, where carpeted homes are common, it can be particularly challenging to eliminate
these allergens, potentially worsening eczema symptoms. A holistic approach, including
reducing other environmental triggers, is essential for managing the symptoms.
Other factors that contribute to eczema include genetics, weakened immune systems, and
stress. Individuals with eczema often have a genetically weakened skin barrier, making their
skin more susceptible to environmental factors. This leads to increased dryness, which can
cause cracks in the skin, allowing bacteria to penetrate and further exacerbate the condition.
If you suffer from dry skin with eczema, it is crucial to pay attention to moisturizing. Always apply
a moisturizer after showering, and reapply it about five times a day whenever your skin feels
dry. While reapplying without washing first is generally fine, be cautious of layering too much
moisturizer without cleansing, especially in oil-prone areas, as it can lead to clogged pores.
When choosing a moisturizer, look for products that mimic the ideal ratio of skin lipids.
Ingredients like ceramides, fatty acids, cholesterol, and glycerol are beneficial for restoring the
skin barrier. Be sure to check that the product is fragrance-free and alcohol-free. If you
experience severe itching, cold compresses can be effective. However, avoid using very cold
items directly on the skin to prevent cold burns; instead, use a cool, damp cloth. Applying a cool
compress over your moisturizer can also help. Additionally, don’t forget to apply sunscreen
during the day, as UV rays can damage the skin and exacerbate dryness due to overall skin
barrier disruption.
