Dry skin and dehydrated skin aren't the same thing.
One is a skin type you're born with. The other is a condition anyone can develop — and treating one like the other is why so much skincare quietly fails.
Most people treat the wrong problem
Reach for a rich, oily cream when your skin feels tight and it may do almost nothing — because the issue was never a shortage of oil. Dryness and dehydration look and feel remarkably similar, yet their causes are opposite.
Get the distinction right and the fix becomes obvious. Get it wrong and you spend years — and a lot of money — on the wrong shelf.
Dry skin: a lack of oil
Dry skin doesn't produce enough sebum — the oily film your sebaceous glands secrete to keep the surface supple. Without it, the outermost layer (the stratum corneum) runs low on the lipids — ceramides, fatty acids and cholesterol — that hold skin cells together like mortar between bricks.
That "mortar" is what keeps moisture in and irritants out. When it's depleted, skin flakes, feels rough and loses its bounce. It's largely genetic, tends to be lifelong, and worsens with age, cold weather and low humidity.
- ◆Flaking, scaling or rough, "papery" patches
- ◆Tightness across the whole face, not just cheeks
- ◆Dullness and visible fine lines from lost lipids
- ◆Rarely gets oily, even in the T-zone
Dehydrated skin: a lack of water
Dehydration is about water content, not oil. Healthy skin holds onto water using its natural moisturising factors (NMFs) — humectant molecules that draw water into the surface cells. When the barrier is compromised, water escapes faster than it's replaced. Scientists call this trans-epidermal water loss, or TEWL.
Because it's a temporary state, dehydration can affect any skin type — including oily and combination skin. It's triggered by weather, central heating and air-con, sun, low water intake, alcohol, caffeine and over-exfoliation.
- ◆Tight, "papery" feeling right after cleansing
- ◆Oily on the surface but still tight underneath
- ◆Fine "crepey" lines that appear then vanish
- ◆Dullness, and make-up that sits unevenly

Dry, oily, sensitive or mature — hydration matters for all
Because dehydration is a condition and not a type, the 24hr Rosehip Serum was built to sit comfortably in any routine — whatever your skin is doing.
How to tell which one you have
You can have both at once — but these three questions point you to the dominant issue.
The pinch test. Gently pinch your cheek. If it creases into fine lines and is slow to bounce back, that points to dehydration.
Check your T-zone. Tight and shiny or oily in places? That's classic dehydration. Tight and never oily? Lean dry.
Does it flake? Persistent flaking and rough patches, all year round, point to genuinely dry skin.
Real skin, real results
In an independent 2024 consumer trial, participants saw a visible difference in how hydrated, nourished and cared-for their skin felt after 30 days.

Susan R.Verified BuyerReviewing24Hr Rosehip Face Serum 30ml - Rated 5 out of 5 stars3 weeks agoWhy didn't I buy this years ago??
Only been using this for 2 weeks, but I could see a difference in my skin straight away. The serum has got rid of dry patches that have bothered me for years. It soaks in quickly, but leaves my face feeling soft and hydrated, and I love the fresh citrus smell....I hate flowery unnatural perfume smells . I have sensitive skin, and usually moisturisers make it spotty after a short while. No problems with this serum at all. I'm hooked!!
