Skin
Dry, flaky skin
Skin that feels rough, tight, flaky or scaly because it is short of moisture — usually down to weather, washing or a tendency to eczema, but sometimes a clue to an underactive thyroid, diabetes or another internal condition.
Education and reference only. This explains the common causes of dry, flaky skin and the warning signs that need urgent help, in plain language — it is not a diagnosis or a substitute for advice from a clinician. If you feel very unwell or are worried, seek medical help.
Quick answer
What is dry, flaky skin?
Dry skin develops when the outer layer loses water faster than it can be replaced, leaving the surface rough, tight, flaky and sometimes itchy or cracked. Most dryness is environmental and harmless: cold or windy weather, central heating, frequent hand-washing, hot baths and harsh soaps all strip away the natural oils that hold moisture in.
- Get urgent help: Seek urgent same-day help if an area of skin becomes hot, red, swollen, spreading and tender, especially with a fever — this suggests infection. Get urgent help if dry, cracked skin develops weeping, pus, increasing pain or red streaks spreading from it.
- Self-care: Most dry skin improves greatly with consistent, gentle care.
About dry, flaky skin
Dry skin develops when the outer layer loses water faster than it can be replaced, leaving the surface rough, tight, flaky and sometimes itchy or cracked. Most dryness is environmental and harmless: cold or windy weather, central heating, frequent hand-washing, hot baths and harsh soaps all strip away the natural oils that hold moisture in. A tendency to dryness also runs in conditions such as eczema and psoriasis, where the skin barrier works less well and inflammation drives flaking and itch. Sometimes, though, widespread or stubborn dryness reflects something internal: an underactive thyroid, long-standing diabetes or reduced kidney function can all leave the skin dry and itchy. Most dry skin responds very well to regular moisturising and gentler washing, but skin that is hot, red, spreading and feverish suggests infection rather than simple dryness.
When to get help
Call 999 or go to A&E if dry, flaky skin comes with any of these warning signs:
- Seek urgent same-day help if an area of skin becomes hot, red, swollen, spreading and tender, especially with a fever — this suggests infection.
- Get urgent help if dry, cracked skin develops weeping, pus, increasing pain or red streaks spreading from it.
- See your doctor promptly if dryness is widespread and stubborn despite good moisturising, with tiredness, weight change or feeling the cold — the thyroid may need checking.
- See your doctor if itching is severe and generalised without an obvious rash, as it can reflect an internal cause.
- Seek advice if cracked skin keeps splitting, bleeding or is slow to heal, particularly if you have diabetes.
When to see a doctor
Ordinary dry skin rarely needs a doctor and usually settles with regular moisturising and gentler washing. Book a routine appointment if dryness is widespread, very itchy, persistent despite good care, or comes with other symptoms such as tiredness, feeling the cold, weight change or excessive thirst, since these can point to a thyroid, kidney or blood-sugar cause that is worth checking. Seek urgent, same-day help if a patch of skin becomes hot, red, swollen and spreading with a fever, or if cracked skin starts to weep, ooze pus or develop red streaks, as these are signs of infection.
Not sure how urgent it is? It is always OK to call NHS 111 for advice, day or night.
What can cause it
Common causes of dry, flaky skin
Dry, flaky skin has many possible causes. Each links to a full, plain-language guide to that condition — what it is, how it's treated and when to seek help.
What helps
Self-care and what you can do
Most dry skin improves greatly with consistent, gentle care. Moisturise generously and often — ideally within minutes of washing while the skin is still slightly damp — using an unperfumed emollient suited to your skin. Swap soap for a soap-free, fragrance-free wash, keep baths and showers short and lukewarm rather than hot, and pat the skin dry instead of rubbing. Protect your hands with gloves during washing-up or cleaning, and use a humidifier or lower the heating if indoor air is very dry. Avoid scratching, which damages the skin and invites infection, and choose soft, non-irritating fabrics. If dryness is widespread, very itchy or not settling despite good care, a pharmacist or doctor can advise on the right products and check for an underlying cause.
Answers
Dry, flaky skin: frequently asked questions
Why is my skin so dry in winter?
Cold, windy air outdoors and dry, heated air indoors both pull moisture from the skin, while hot baths and frequent washing strip its natural oils. Moisturising often, washing in lukewarm water and using a humidifier usually make a big difference.
Can dry skin be a sign of a thyroid problem?
It can. An underactive thyroid commonly leaves the skin dry and rough, often alongside tiredness, weight gain and feeling the cold. If dryness is widespread and stubborn with these features, ask your doctor to check your thyroid.
How do I tell dry skin from an infection?
Dry skin is rough, flaky and tight but not hot or spreading. If an area becomes hot, red, swollen, increasingly painful or feverish, or starts to weep or ooze, that suggests an infection and needs urgent, same-day assessment.
What is the best way to moisturise dry skin?
Apply a generous amount of an unperfumed emollient soon after washing, while the skin is still slightly damp, and reapply through the day as needed. Using a soap-free wash and avoiding hot water helps the moisturiser hold water in the skin.
