Making Sense of Dry Skin
Dry Skin: what it is, why it matters, and what published guidance actually asks of you.
Most cases are caused or worsened by washing habits, which makes them unusually easy to improve.
Key takeaways
- Main aggravators: soap, hot water, long showers, central heating, wind
- Emollient timing: within a few minutes of washing, on damp skin
- Most useful single change: Switch from soap to a soap substitute.
- Commonest mistake: Soap, bubble bath and detergent-based washes.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
The short answer
Skin that has lost water and lipid from its outer barrier, becoming rough, tight or flaky.
Where it fits
This is part of Skin Health. The rest of this page works through the figures and then the practical side.
The numbers, in one place
| Measure | Figure |
|---|---|
| Main aggravators | soap, hot water, long showers, central heating, wind |
| Emollient timing | within a few minutes of washing, on damp skin |
| Ointments | greasier and more effective than lotions for very dry skin |
| Fire risk | emollients on clothing and bedding are flammable |
What that means in practice
In everyday terms:
- Switch from soap to a soap substitute
- Apply emollient to damp skin straight after washing
- Use lukewarm rather than hot water and keep showers short
- Apply more often in cold weather
What gets people into trouble
And the things that tend to go wrong:
- Soap, bubble bath and detergent-based washes
- Very hot or very long showers
- Smoking or naked flames near emollient-soaked fabric

When to speak to a doctor
See a GP if dry skin is severe, not improving with emollients, or accompanied by intense itch without a rash, which can indicate liver, kidney or thyroid disease or iron deficiency. Seek urgent advice for skin that is weeping, crusting, painful or spreading, suggesting infection.
Where this comes from
How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
