How to Tell If Your Skin Is Dehydrated: 5 Quick Signs

Your skin feels tight by mid-morning. It looks a little flat and lacklustre in photos. And no matter how much moisturiser you smooth on at night, it never quite feels quenched. So you do what we all do — you Google it — and now you're wondering: is my skin actually dry, or is it dehydrated? And is there even a difference?

There is. And the lovely news is you can work this out yourself, tonight, in a few minutes, with nothing but your own two hands and a mirror. Let me walk you through it, the same way I figured it out on my own skin.

First, dehydrated isn't the same as dry

This trips up so many of us, so let's clear it up right away.

Dry is a skin type — it means your skin doesn't make much oil. You're often born that way, and it tends to stay with you.

Dehydrated is a condition — it means your skin is short on water, and it can come and go. Here's the part that surprises people: dehydration can happen to anyone. Oily skin, combination skin, even skin that still breaks out — all of it can be thirsty underneath. So yes, you can absolutely be shiny and dehydrated at the same time.

(If you want the full side-by-side, I've written a whole piece on dry skin vs dehydrated skin — worth a read once you've done the checks below.)

The pinch test — try it right now

This is the quickest tell there is, and you can do it while you read this.

Gently pinch a small bit of skin on your cheek (or the back of your hand) between your thumb and finger, hold it for a second or two, then let go. Watch how it settles.

• Bounces straight back? Your skin is holding water nicely.
• Takes a moment, or looks a little crêpey as it settles? That's a classic sign your skin could do with more hydration.

It's not a lab test, so don't panic over one slow bounce — but paired with the signs below, it tells you a lot.

The other everyday signs to look for

The pinch test is a great start. Now here are the five things I'd genuinely notice on my own face when my skin was crying out for water.

1. Tightness that won't quit

That "clean but a bit stretched" feeling after you wash, especially if it lingers instead of easing once your skin settles. Dehydrated skin often feels tight across the cheeks and forehead — like there isn't quite enough of it to go around.

2. Dullness — the lost-glow look

Well-hydrated skin bounces light back, which is what we read as glow. When it's low on water, the surface goes a little flat and grey-looking, and your usual highlighter or blush just doesn't sit as prettily. If people used to say you looked "well-rested" and lately you look tired even when you're not — hydration is often the missing piece.

3. Fine surface lines that plump up when you moisturise

This is the giveaway I love, because it's so telling. Look closely at your under-eyes and cheeks. Dehydration lines are fine, shallow and often make a little criss-cross or crêpey pattern — and here's the tell: they soften the moment you press in a hydrating product. True ageing wrinkles don't vanish like that, but dehydration lines plump back up as soon as the water goes back in. If yours come and go, they're mostly a thirst signal, not a permanent change.

4. Oily but flaky — the confusing one

If you've ever thought "my skin is greasy and peeling, that makes no sense" — it actually does. When skin is short on water, it can panic and pump out more oil to protect itself. So you end up shiny in the T-zone but with little dry, flaky patches around the nose, mouth or hairline. It feels contradictory, but it's very often dehydration wearing a disguise.

5. Everything drinks in and still feels thirsty

You moisturise, and twenty minutes later your skin feels like it soaked it all up and wants more. That "I can't get enough on" feeling is dehydrated skin reaching for water it can't hold onto yet.

Why it happens — and why it's so common past 40

None of this means you've done something wrong. Skin loses water more easily as we get older, partly because its natural moisture-holding ability quietly winds down. Add in our South African realities — a dry Highveld winter, air-conditioned offices, heaters, long hot showers, hard water — and it's no wonder so many of us feel parched.

And if you're somewhere in the perimenopause years, there's an extra layer: as oestrogen dips, skin holds noticeably less water. If your skin has changed lately in ways that caught you off guard, you might recognise yourself in how menopause changes your skin. It's not just you, and it's not forever.

The easy fixes — most of them are free

Good news: dehydrated skin usually responds quickly once you give it what it's missing. Start here.

• Turn the temperature down. Wash with lukewarm water, not hot — hot water strips the very oils that help your skin hold moisture.
• Stop over-cleansing. Twice a day is plenty. If your skin feels squeaky and tight after cleansing, your cleanser is too harsh.
• Moisturise onto slightly damp skin. This is the single best free trick. Pat your face nearly dry, then apply your hydrating step while it's still a little damp — you trap that water in instead of letting it evaporate.
• Don't skip moisturiser because you're oily. Oily, dehydrated skin needs water most of all. Reach for lighter, water-based formulas rather than skipping the step.
• Mind your environment. A bowl of water near a heater, a humidifier, or simply a mist through a long aircon day all help.
• Drink your water, gently. It won't fix everything on its own, but tired, thirsty skin and a well-hydrated you tend to go together.

Where a little extra help comes in

If you've done the tests and thought "yes, that's me," the step that makes the biggest difference is adding water-attracting hydration your skin can actually hold onto — and that's exactly what hyaluronic acid does.

This is where I quietly reach for Avroy Shlain's CRT 3-in-1 Hydration Serum. It's built around hyaluronic acid to plump and deeply hydrate — Avroy Shlain's own testing shows 45% more hydration in 4 weeks — and it's oil- and fragrance-free, so it suits oily and combination skin just as happily as dry. Only three or four drops onto slightly damp skin, morning and night, before your moisturiser. A little truly goes a long way, so one bottle lasts months.

And for that thirsty, tight feeling during the day — mid-afternoon at your desk, or after a flight — the CRT 4-in-1 Hydrating Mist is a lovely instant drink of water for your face. A quick spritz soothes, refreshes and softens those dehydration lines, and it sits beautifully over makeup.

Start with the serum, add the mist for top-ups, and give it a couple of weeks. Most women are genuinely surprised how much plumper and brighter thirsty skin looks once it's finally holding water again.
