You cleanse gently. You moisturise morning and night. You read ingredient lists, patch test new actives, maybe you have even seen a dermatologist. And still, your skin can feel tight, look dull, or break out for reasons that are hard to pin down.

Before you replace another product, it is worth looking at the one thing every routine has in common: water. You wash with it, rinse your cleanser with it, and put the rest of your skincare on straight afterwards. If your tap water contains a lot of chlorine, heavy metals or sediment, it may be making things harder for your skin before your routine has even properly started.

The part of your routine most people ignore

When something stops working, we usually blame the products. The new serum. The retinol. The moisturiser. The cleanser. Water rarely gets questioned because we tend to think of it as neutral.

But tap water is not just H2O. Depending on where you live, it can contain disinfectants such as chlorine, dissolved minerals and trace metals. And your skin is exposed to it every time you wash your face.

That matters because whatever is in the water can be left behind on the skin after rinsing. Then your moisturiser, serum or treatment goes on top.

Three signs your water might be affecting your skin

1. Your skin feels tight after washing

If your face feels tight or uncomfortable a few minutes after cleansing, it does not necessarily mean your cleanser is too harsh. Chlorine and hard water can also contribute to that stripped feeling, especially if your skin is already dry or sensitive.

If you are using a gentle cleanser and still notice tightness after washing, the water itself is worth considering. Read more about how chlorine can affect the skin.

2. Moisturiser only seems to help for a short time

If your skin feels comfortable immediately after moisturising but dry again not long afterwards, you may be dealing with more than a lack of hydration.

When the skin barrier is irritated, it can lose moisture more easily. Using a richer cream may help, but it does not always address what is causing the irritation in the first place.

3. Your skin changes when you travel or move

This is one people often notice without connecting it to water. Your routine stays exactly the same, but your skin suddenly feels better or worse after moving house, visiting another city or spending a week abroad.

One possible reason is hard water. Calcium and magnesium in hard water can react with cleansers and leave residue on the skin, which may be more noticeable if your skin is sensitive or prone to dryness. Read more about hard water, dryness and breakouts.

Think about what happens when you travel

If you are wondering whether your water could be part of the problem, think back to a recent trip. Did your skin change even though you packed the same products?

There are obviously plenty of things that change when you travel, including weather, humidity, sleep and diet. But the water changes too. If you notice the same pattern every time you move between places, it is worth paying attention to.

Start with the water

This does not mean your skincare products are not working. It simply means they are being applied to skin that has just been washed in whatever comes out of your tap.

For people who already pay close attention to cleansers, serums and moisturisers, looking at the water is a fairly logical next step.

That is also why filtering at the bathroom sink makes sense. A shower filter can be useful for the water you shower in, but most people wash their face at the faucet. The brume faucet filter attaches to your bathroom tap and filters chlorine, heavy metals and sediment before the water reaches your skin.

The bottom line

If you have changed your cleanser, switched moisturisers and experimented with different routines but your skin still feels off, your products may not be the only thing worth looking at.

You wash your face with tap water every day. It is worth knowing what is in it.
