What Causes Eczema Flare-ups? - Discovering Your Triggers and the Switcheroo Technique.
Learn how to identify and manage your eczema triggers to help reduce flare-ups.
Key Takeaways
An important part of managing eczema is by first understanding what's causing it. Similar to driving without a GPS, it's impossible to know where you're headed if you have no directions or coordinates. That's why in this blog we'll cover the common causes of flare-ups, how to reduce their impact and how you can discover your own eczema triggers.
Eczema Triggers - The Key To Preventing Flare-Ups
One of the best ways to prevent flare-ups is by controlling your triggers. They damage the skin by causing irritation. This leads to inflammation, which weakens the skin barrier. To bring them under control, you need to be aware of the various shapes that they can take. Triggers tend to come in 4 flavours:
Personal
Environment
Irritants
Foods
Here’s a breakdown of what they include:
Personal - These are anything you're in control of that may trigger your eczema. They include your mood, sleep, skincare routine, exercise, diet and water intake.
Environmental – These are environmental factors often out of your control — weather, pollen, humidity and air pollution.
Irritants – Some substances can cause you trouble without realising it. Irritants are a prime example. They tend to be found in products such as soaps, shampoos and fragrances. Their ingredients have been scientifically recognised as irritating many people's skin, not just those with eczema.
Foods – Allergies, intolerances and certain foods like eggs have been shown to irritate the skin of those with eczema.
A Breakdown Of Common Causes Of Eczema Flare-Ups
1. Personal Factors:
Sleep: Lack of sleep or irregular sleep patterns can weaken the immune system and exacerbate eczema symptoms.
Stress: Stress can cause a hormonal imbalance and immune system response that may trigger flare-ups.
Hormonal Changes: Fluctuations in hormone levels, such as during menstrual cycles or pregnancy, can impact eczema.
Illness: Common colds, the flu, or infections can stimulate an immune response leading to a flare-up.
2. Environmental Factors:
Weather: Dry, cold air can make the skin more prone to dryness and itching. Conversely, hot, humid weather can lead to sweating and irritation, triggering a flare-up.
Allergens: Environmental allergens such as dust mites, pollen, mould, and pet dander can trigger eczema in some people.
Hard Water: High mineral content in water can dry out the skin and exacerbate eczema.
3. Irritants:
Soap and Detergents: Harsh soaps, shampoos, and laundry detergents can strip away the skin's natural oils, causing dryness and irritation.
Clothing: Synthetic fabrics or wool can be irritating to the skin. Cotton clothing is generally better tolerated.
Fragrances and Dyes: Artificial fragrances and dyes in personal care products can be irritating to sensitive skin.
Sweat and Saliva: In babies, drool can be a skin irritant. In adults and children, sweat can also cause irritation and lead to a flare-up.
In addition, there are several ingredients that are found in various products including skincare ingredients. You should be on the lookout for the following:
Fragrance: This is a broad term that can encompass thousands of individual ingredients, many of which can cause skin irritation or allergic reactions.
Sodium Lauryl Sulfate (SLS) and Sodium Laureth Sulfate (SLES): These are commonly used as foaming agents in soaps, shampoos, and body washes. They can strip the skin of its natural oils, leading to dryness and irritation.
Parabens (methylparaben, propylparaben, butylparaben, and ethylparaben): Used as preservatives in many skincare products, parabens can cause skin irritation in some people.
Formaldehyde and Formaldehyde-releasing Preservatives: These are used to prolong the shelf-life of skincare products. However, formaldehyde is a known allergen that can cause skin reactions.
Alcohol (denatured alcohol or isopropyl alcohol): Found in many skincare products, it can dry out the skin, leading to irritation and potential flare-ups.
Retinol and Retinoids: While these can have benefits for many skin types, they can also cause irritation and dryness, particularly for those with sensitive skin or eczema.
Essential Oils: Though natural, many essential oils can be irritating to the skin. Examples include citrus oils like bergamot or grapefruit, and others like peppermint.
Dyes: Artificial dyes can be a trigger for some people with eczema.
Propylene Glycol: It's used in a variety of skincare products to enhance product penetration, but can be irritating to the skin.
4. Foods:
Dairy: Dairy products, particularly cow's milk, can be a trigger for some people.
Eggs: Eggs are a common allergen and can trigger eczema in some people.
Gluten: Some individuals with eczema may have a sensitivity or intolerance to gluten.
Nuts and Seeds: Nuts and seeds are common allergens that can trigger eczema in some people.
Soy: Soy and soy products can be a trigger for some people.
