You changed countries, but did you think about what changed in your water? The impact of hard water on your skin.
If your skin has become drier, tighter, more reactive or simply different since moving or travelling, it's easy to assume your skincare is no longer working. Before replacing your entire routine, it's worth considering whether the water you're washing your face with has changed too.
Water hardness varies significantly between countries and regions, and for skin that is already dry, sensitive, reactive or barrier-impaired, that change may be more relevant than you think.
What is hard water?
Hard water contains higher concentrations of dissolved minerals, primarily calcium and magnesium. These minerals enter the water as it travels through mineral-rich rock and soil, which is why water hardness can vary considerably depending on where you live.
If you've noticed white deposits building up around your taps, shower screen or kettle, you're already seeing the effects of mineral-rich water. Unfortunately, your kettle isn't the only thing repeatedly exposed to it.
This doesn't mean calcium and magnesium are inherently bad for the skin. What interests us from a skin health perspective is how hard water interacts with cleansing products and the skin surface over time.
What happens when hard water meets your cleanser?
Cleansers contain surfactants, which help water interact with oils and debris so they can be removed from the skin. Minerals in hard water can interact with certain surfactants and affect how effectively a cleanser rinses away, potentially contributing to deposits or residue remaining on the skin.
For someone with healthy, resilient skin, this may cause very little noticeable change. However, if the skin barrier is already compromised, repeated exposure alongside cleansing, hot water, active skincare and other environmental factors may contribute to dryness, tightness and irritation.
This is particularly relevant when a client tells me their skin feels uncomfortable immediately after washing.
That tight, squeaky-clean feeling is not necessarily a sign that you've done an excellent job cleansing. It can be a sign that your cleansing routine is removing more from the skin surface than your barrier is comfortable with.
Why the skin barrier matters
Your skin barrier forms part of your body's protection from the outside environment. It helps retain water within the skin while limiting the entry of potential irritants and allergens. When barrier function becomes compromised, the skin may lose water more readily and become increasingly vulnerable to external stressors. You might notice dryness, rough texture, increased redness, sensitivity or products suddenly stinging when they previously felt completely fine.
This can also create a frustrating cycle. Skin begins to feel rough, so we exfoliate it. When the texture doesn't improve, we exfoliate more or introduce another active ingredient, when what the skin may actually need is less stimulation and greater barrier support.
Sometimes the answer to unhappy skin isn't another serum. Your bathroom cabinet can stand down.
Does hard water cause skin conditions?
This is where it's important not to oversimplify the science.
Research has identified associations between hard water exposure, skin barrier function and conditions such as atopic dermatitis and eczema. That doesn't mean hard water directly causes every case of dry, sensitive or inflammatory skin.
Conditions such as rosacea, acne, eczema and dermatitis are multifactorial. Genetics, immune function, hormones, barrier health, lifestyle and environmental exposures can all contribute.
I prefer to think of hard water as a potential environmental amplifier rather than automatically labelling it as the cause.
Someone may already have a vulnerable skin barrier and then move somewhere with harder water. Add a cold winter, indoor heating, lower humidity, stress and perhaps a slightly enthusiastic skincare routine, and suddenly their skin isn't coping as well as it once did. The water may not be the whole story, but it can still be part of it.
What about the skin microbiome?
The skin surface is home to a diverse community of microorganisms collectively known as the skin microbiome. This ecosystem interacts closely with the skin barrier and immune system and is influenced by the environment we create at the skin surface.
Cleansing habits, skincare products, temperature, humidity and pH can all affect this environment.
Water exposure may also play a role, although research into the skin microbiome is still developing and I would be cautious of claims that hard water simply "destroys" it.
Skin biology is rarely that black and white. As much as social media would love every skin concern to have one villain and one miracle ingredient, the reality is usually more complicated.
Why I ask clients where they lived before
When I'm assessing someone's skin, knowing where they live now is useful, but knowing where they lived when their skin began to change can be even more valuable.
Perhaps you spent years living somewhere with relatively soft water and a humid climate before moving to Switzerland. Your skin is now dealing with different water, colder winters, lower humidity and indoor heating. If your skin changed during that transition, it's worth exploring.
Moving country can change your water hardness, climate, humidity, UV exposure, pollution exposure, heating, air conditioning, diet, stress levels and daily routines at the same time.
It would therefore be too simplistic to say, "It's definitely the water", but it would be equally simplistic to ignore the environment altogether.
This is why timelines matter so much in a skin consultation. Understanding when a change began and what was happening around that time can give us valuable clues about what may be influencing the skin today.
What can you do if you live in a hard-water area?
You don't need to start washing your face exclusively with bottled water or completely overhaul your skincare routine.
Start with your cleansing habits. If your skin consistently feels tight, dry or uncomfortable immediately after cleansing, consider whether your cleanser is appropriate for your current skin condition and avoid using very hot water.
If the skin feels rough, resist the temptation to automatically reach for stronger exfoliation. Roughness can also occur when the barrier is dehydrated or compromised, and repeatedly removing more from the surface may make the problem worse.
A simple, barrier-supportive routine is often a better starting point. The aim should be to cleanse effectively without unnecessarily stripping the skin, maintain hydration and support the lipids and structures involved in healthy barrier function.
If you live in an area with particularly hard water and notice a consistent relationship between washing and skin discomfort, you could also investigate an appropriate water filtration or softening solution. I would view this as one potential adjustment within a wider skin strategy rather than a guaranteed solution.
Most importantly, think about the timeline of your skin changes. Consider whether they appeared after moving home or country, travelling, changing jobs, entering a different climate or spending significantly more time in heated or air-conditioned environments.
Those details can sometimes tell us far more than adding another product to the shelf.
Your environment is part of your skin story. Skincare products and treatments absolutely matter, but your skin doesn't function independently from the environment around it.
The water you wash with, the climate you live in, humidity, temperature, UV exposure and your daily habits all form part of the environment your skin has to continually adapt to.
This is why my consultations at JANORÀ Skin Studio go beyond asking which cleanser and moisturiser you use. I want to understand when your skin changed, what was happening at the time and what factors may still be influencing it today.
I don't believe in pretending there is always one simple answer. Skin is complex, and good skin therapy is often about identifying patterns, removing unnecessary stressors and supporting the skin rather than
constantly trying to force it into behaving differently.
So if your skin has changed since moving country, don't immediately assume your skincare has stopped working. Take a look at what else changed around the same time. The answer may not be another product. It might simply start with looking at what's coming out of your tap.
Has your skin changed and you're not sure why?
A skin consultation at JANORÀ Skin Studio looks at more than what we can see on the surface. We explore your skin history, current routine, lifestyle and environmental influences to better understand what your skin may be responding to and what it actually needs.
