Why skin hydration matters in winter (and how to get it right)
Cold air outside, central heating inside and hot showers in between: winter is hard on skin. Many people notice tightness, flaking, dullness or redness from November onwards and assume they just need a thicker cream. In fact, keeping skin well hydrated through the winter months is about protecting its natural barrier, and the right routine can make a real difference within a couple of weeks.
In this guide I explain, as a doctor, what skin hydration actually is, why winter makes things worse, and the simple steps I recommend to keep your skin comfortable, smooth and healthy until spring. It builds on my guide to a simple skincare routine.
What skin hydration really means
When we talk about hydrated skin, we mean skin whose outer layer, the stratum corneum, holds enough water to stay soft, supple and comfortable. That outer layer works like a brick wall: skin cells are the bricks, and natural fats such as ceramides, cholesterol and fatty acids are the mortar that holds them together.
When this barrier is healthy, it keeps water in and irritants out. When it is disrupted, water escapes from the skin more quickly, a process called transepidermal water loss. The result is skin that feels tight, looks dull and becomes more sensitive to products it normally tolerates.
So good hydration is not just about adding water. It is about helping the skin hold on to the water it already has.
Why skin gets drier in winter
Several things happen at once in the colder months:
- Low humidity. Cold air holds much less moisture, so water evaporates from the skin more easily.
- Central heating. Indoor heating dries the air further, often for many hours a day.
- Wind and cold. Exposure to wind strips moisture from exposed skin on the face, lips and hands.
- Hot showers and baths. Very hot water dissolves the skin’s natural oils, weakening the barrier.
- Changes in routine. Heavier clothing, more hand washing and sanitiser in cold and flu season all add to the strain.
The combination means even people with oily or combination skin in summer can find their skin feels dry, tight or sensitive in winter.
Dry skin or dehydrated skin?
These terms are often used interchangeably, but they mean slightly different things, and knowing which you have helps you choose the right products.
Dry skin
A skin type. Dry skin produces less oil (sebum), so it tends to feel rough or flaky all year round and needs richer, oil-based products to replace what it lacks.
Dehydrated skin
A temporary skin condition. Dehydrated skin lacks water, not oil, so it can affect any skin type, even oily skin. It often looks dull, shows fine lines more and feels tight, especially after cleansing.
In winter, many people have both. The good news is that the routine below helps either way.
Does drinking water hydrate your skin?
Drinking enough water is important for your overall health, and if you are genuinely dehydrated it will show in your skin as well as your energy levels. Aim to drink regularly through the day so your urine stays pale yellow, and remember that we often drink less in winter because we don’t feel as thirsty.
However, for most healthy people, drinking extra water beyond what the body needs won’t noticeably change how hydrated the skin’s surface is. That depends far more on the health of the skin barrier and the environment around it. So drink well, but don’t rely on water alone: what you put on your skin, and how you treat it, matters most.
A winter skin hydration routine
You don’t need a long list of products. Here is the simple routine I suggest for winter, adapted from the year-round vitamin C, vitamin A and SPF routine.
Morning
- Cleanse gently with lukewarm water and a mild, non-foaming cleanser, or simply rinse if your skin is very dry.
- Apply a hydrating serum to slightly damp skin. Look for humectants such as hyaluronic acid, glycerin or panthenol (vitamin B5), which draw water into the skin.
- Vitamin C serum, if you use one, for antioxidant protection.
- Moisturiser. Choose one with ceramides, squalane or shea butter, which help repair the barrier and lock moisture in. You may need a richer formula in winter than in summer.
- Broad-spectrum SPF 30 or above, every day. UVA rays, which cause skin ageing, are present all year round, even on cloudy days.
Evening
- Cleanse to remove SPF and make-up. A cleansing balm or oil can be gentler on dry skin.
- Hydrating serum on damp skin.
- Vitamin A (retinol or retinal), if you use it. If your skin feels irritated in winter, use it less often or apply it after your moisturiser to buffer it.
- A richer night moisturiser to support the barrier while you sleep.
If your skin is stinging, red or flaking, simplify: pause exfoliating acids and strong actives for a week or two, and focus on gentle cleansing, hydration and barrier repair until it settles.
Everyday habits that help
- Keep showers short and warm, not hot, and pat skin dry rather than rubbing.
- Moisturise within a few minutes of washing, while the skin is still slightly damp.
- Use a humidifier or place a bowl of water near radiators if your home feels very dry.
- Protect your hands and lips. Wear gloves outdoors, use hand cream after washing, and apply a lip balm with SPF.
- Don’t over-exfoliate. Once or twice a week is plenty in winter.
- Eat well. Healthy fats from oily fish, nuts, seeds and avocado support skin health. My recipes are a good place to start.
- Sleep. Skin repairs itself overnight, so a good night’s rest shows. See my guide to sleep and mind.
Treatments that can help
For many people, the right home routine is enough. If you’d like extra support, some professional treatments can help improve skin texture and hydration over the winter months:
- Medical-grade skincare. Professional products contain well-researched active ingredients at effective strengths. A personalised routine can take the guesswork out of choosing products.
- Chemical peels. Gentle, professional peels remove dull, dry surface cells so your skin can absorb hydrating products better. Winter is an ideal time, as there is less sun exposure.
- Dermaroller skin needling. Stimulates the skin’s own repair processes to improve texture and tone over a course of treatments.
- Skin boosters, such as Profhilo. A hyaluronic acid treatment designed to improve skin hydration and quality from within.
All treatments are carried out at home by a doctor after a free video consultation and a face-to-face assessment. You can see prices and details on the Treatments page.

When to see a doctor
Most winter dryness improves with simple changes. Speak to your GP or a pharmacist if your skin:
- is cracked, bleeding or very itchy
- has red, scaly or inflamed patches that don’t settle with moisturiser, which can be a sign of eczema or psoriasis
- shows signs of infection, such as weeping, crusting, swelling or increasing pain
- is affecting your sleep or daily life
Frequently asked questions
Should I use a different moisturiser in winter?
Often, yes. Many people benefit from switching to a richer moisturiser containing ceramides or other barrier-repairing ingredients in winter, then going back to a lighter one in spring.
Do I really need sunscreen in winter?
Yes. UVA rays, which contribute to skin ageing and pigmentation, are present all year round and pass through cloud and glass. A daily broad-spectrum SPF 30 or above is one of the best things you can do for your skin.
Is hyaluronic acid good for dry skin?
Hyaluronic acid helps draw water into the skin, so it suits most skin types. Apply it to slightly damp skin and follow with a moisturiser to seal the hydration in, especially in dry, heated rooms.
Can I keep using retinol in winter?
Usually, yes. If your skin becomes irritated, use it less often, apply it after moisturiser, or take a short break until your skin settles.
How quickly will my skin improve?
With a gentle, consistent routine, most people notice their skin feels more comfortable within one to two weeks.
