What causes eczema — and how to manage it


The epidermis is a marvellous organ.

Not only is it vital for our survival, but it allows us to touch and be touched, and protects us remarkably well from environmental damage.

However, eczema brings out the fragile side of our skin – it gets covered in itchy, dry patches! If we want our skin to protect us, we have to protect it too.



The causes are unclear


Why are some of us so prone to eczema? Many studies on atopic eczema (or atopic dermatitis), the most common form of the disease, have tried to uncover the reasons behind the condition.

What we know so far is that this chronic ailment, which is generally hereditary, is commonly found in people who also suffer from allergies and asthma1.

Environmental factors can also trigger flare-ups. However, the exact causes of eczema remain a mystery.



A prevalent condition


  • One-third of the population will suffer from eczema (atopic dermatitis) in their lifetime.
  • Hand eczema affects one out of ten people.
  • Hand eczema affects one out of ten people.
  • A third of children suffering from eczema have a moderate or severe form of the disease.


The body under attack

Eczema’s flare-ups, on the other hand, are well known. Like an unwelcome guest, it shows up uninvited, outstays its welcome, then disappears… before coming back with a vengeance elsewhere on the body.

In babies, eczema is often seen on the forearms, legs, forehead, neck, cheeks and scalp.

Adults often have lesions on the hands, face, neck, ankles and inside the elbows and knees. While sufferers often try to hide the affected areas, it’s not always easy – especially in the summer!



Multiple triggers


There are many potential eczema triggers. But did you know that many of them can be found in your kitchen and bathroom? Products that you use every day – including shampoo, soap, sunscreen, detergent and disinfectant – can contain many irritating ingredients.

If you have allergies, your triggers (dust mites, mold, pollen, chemicals, etc.) can also aggravate your condition. Lastly, environmental factors like cold weather, excessive heat or tobacco smoke, can cause symptoms to reappear or get worse2.



How to protect yourself?

If you want to soothe and control eczema, you need to protect yourself! This means minimizing your exposure to environmental factors and offending allergens, while also reducing contaminants and irritating chemicals in your household. (this also goes for those with sensitive skin, who make up around 50% of the population!)

But now that so many common personal care and household products contain ingredients of concern, what’s an eczema sufferer to do? Thankfully, organizations like the Environmental Working Group (EWG) are here to help.

Here are some ingredients they advise against if one or more family members suffer from sensitive skin :



Petrochemical derivatives, which contain carcinogens :


  • Sodium laureth sulfate (contaminated with 1,4-dioxane, a probable carcinogen)
  • Polyethylene glycol (contaminated with 1,4-dioxane)
  • DMDM hydantoin (releases formaldehyde, a carcinogen)
  • Polyquaternium-7 (contaminated with acrylamide, likely carcinogen)



Perfumes or fragrances, which can contain over a hundred ingredients including :


  • Diethyl phthalate (an endocrine disruptor)
  • Limonene (an allergen/known irritant)

Look for products with the “EWG Verified” logo, which ensures the absence of contaminants and irritating chemical substances. You can also seek out the NEA (National Eczema Association) Seal of Acceptance, sensitive skin product.



To hydrate is to protect

Another easy way to feel better in your skin: up your hydration. Since dry skin is more vulnerable, frequently using a good moisturizer will also protect you against irritants, which means fewer eczema flare-ups3.


Naturally-sourced skincare products are your best ally in the fight against dry skin. Those enriched with oatmeal, are particularly recommended to soothe a fragile epidermis. Thanks to its many active components, this ingredient, recognized by Health Canada, relieves skin irritation, reduces redness and calms itching..


Just like oatmeal is great to curb your appetite, lotions or shower gels infused with oatmeal extract or colloidal oatmeal are known to nourish dry and sensitive skin. When they penetrate the epidermis, the multivitamins and minerals contained in oats help retain water while strengthening the protective barrier of the skin to promote hydration4.

And if your skin still tends to dry out throughout the day, bring your hand cream along with you – you’ll always be prepared!



5 benefits of oatmeal for sensitive skin


  • Nourishes for better hydration
  • Reduces redness caused by dryness
  • Soothes itchiness caused by dryness
  • Softens the skin
  • Gentle cleanser


Water: friend or enemy?


Water can help hydrate your skin, but don’t go overboard! Taking baths and showers that are too hot or too long can dehydrate, because they strip the skin of its natural protective oils. So, while it sure can be nice, be careful not to take your time in the shower or bath and keep the water lukewarm to preserve your precious oils.


Should you avoid regularly washing your hands to keep them from drying out? Absolutely not!

But again, use lukewarm water and a gentle cleanser, like a sulfate-free hand soap. – yes, every time you wash your hands! Your skin will thank you.
