Winter skin in Canada: how to support your skin barrier
In a Canadian winter, cold outdoor air and dry indoor heat make it harder for your skin to hold on to moisture, so it can feel tight, rough or itchy. You can support your skin barrier with shorter warm showers, a richer moisturizer applied to damp skin, a facial oil to seal it in, and more humidity in the air at home.
This article is for anyone who notices their skin change between November and March. You'll learn what the skin barrier is, why winter is hard on it, and a simple routine that may help your skin feel comfortable again.
Why does skin get so dry in a Canadian winter?
Because the air is dry both outside and in. Cold air holds very little moisture, and the American Academy of Dermatology notes that the drop in temperature and humidity makes it harder for skin to retain water. Indoors, furnaces and fireplaces create dry heat that takes even more moisture out of the air.
Health Canada notes that humidity in Canadian homes tends to be lower in winter than in summer. Add long hot showers, wind on the walk to work, and moving between heated rooms and the cold, and your barrier is working harder than it does the rest of the year.
Dry, tight skin in winter is common. Skin that cracks, bleeds, itches enough to keep you awake, or doesn't improve with gentle care is worth showing to your healthcare provider or a dermatologist.
How can you support your skin barrier in winter?
Keep it simple: protect the water your skin already has, then seal it in. These steps follow the American Academy of Dermatology's advice for dry skin.
- Shorten your shower. Keep it to 5 to 10 minutes, in warm rather than hot water, and pat your skin dry instead of rubbing.
- Cleanse gently. Choose a mild, fragrance-free cleanser, and consider cleansing your face once a day with just water in the morning if your skin feels tight.
- Moisturize while your skin is still damp. Apply within a few minutes of washing, then again whenever your skin feels dry.
- Seal it in. Press a few drops of facial oil over your moisturizer, or use it on its own at night if your skin prefers fewer layers.
- Ease off strong actives. If your skin stings, use exfoliating acids or retinoids less often until it feels comfortable again.
- Add moisture to the air. A humidifier in the bedroom overnight can help. Clean it regularly so mould doesn't grow.
Cream, lotion or oil: what works best in winter?
In winter, creams and ointments generally hold moisture better than lotions, and a facial oil can add a final layer that slows water loss. Each does a slightly different job.
A simple winter order: a light serum such as Osmosis StemFactor, then a cream such as Osmosis Hydrate Plumping Moisturizer, then a few drops of oil to finish.
If your skin feels stressed, tight or easily irritated, a calming repair serum can take the place of your usual one. SIV Biome Balancing Serum works alongside your skin's microbiome to help it look calm and balanced, and Osmosis Rescue Epidermal Repair Serum is a short, six-ingredient formula for skin that looks red or stressed.
| What it does | Best for | |
|---|---|---|
| Lotion | Light and water-rich; absorbs quickly | Summer, or oily skin that still wants hydration |
| Cream | Thicker, with more oils; holds moisture longer | Most skin in winter, especially dry or tight skin |
| Facial oil | Softens skin and helps seal in the water underneath | A final step over moisturizer, or on its own at night |
| Serum | A light layer of targeted ingredients | Under moisturizer, when you want extra support |
Look for ingredients the American Academy of Dermatology lists for dry skin, such as glycerin, hyaluronic acid, jojoba oil, shea butter and dimethicone. Squalane is another gentle option: it's a stable form of squalene, one of the lipids found in the skin's own oil, and it's the single ingredient in our N°1 Squalane Oil. Fragrance-free is the safest choice when your skin feels reactive.
Does what you eat and drink affect winter skin?
It can play a part, but topical care does most of the work for the barrier. Staying hydrated, eating a varied diet with healthy fats, and getting enough sleep all support your body as a whole, and your skin is part of that.
Think of NOURISH as both directions at once: what you put on your skin, and how you look after the body underneath it. Neither replaces the other, and neither replaces medical care when you need it.

FAQ
Why is my skin so dry in winter?
Cold outdoor air and indoor heating both lower the humidity around you, so your skin loses water more easily. Long hot showers and harsh cleansers can add to it by stripping the lipids that hold the skin barrier together.
How do I know if my skin barrier is struggling?
Common signs are tightness after washing, flaking, rough patches, dullness, and stinging from products that usually feel fine. If you notice cracking, bleeding or a persistent rash, see your healthcare provider.
Should I use a facial oil or a moisturizer in winter?
Often both. Apply your moisturizer to damp skin, then press a few drops of oil, such as N°5 Rose Oil, on top to help seal it in. If your skin prefers fewer layers, an oil on its own at night can be enough.
Is squalane good for dry winter skin?
Squalane is a lightweight, stable oil similar to a lipid your skin already makes, and it's the single ingredient in our N°1 Squalane Oil. Many people with dry or sensitive skin find it comfortable, and it's a simple way to add a protective layer in winter.
Does a humidifier help dry skin?
It can. The American Academy of Dermatology suggests running a humidifier, especially in the bedroom overnight, when the air is dry. Clean it regularly to prevent mould.
