Dry Skin: What Is Known and What May Help
General information · not medical advice
Dry skin means the outer layer is not holding water, and the fix is usually to put water in and seal it. This page sets out what is known, then lists products on the facts their labels carry.
What is known

Why skin dries out
The outer layer of skin needs water and fats to stay flexible. Cold weather, low humidity, long hot showers, harsh soaps and ageing all strip those fats or draw water out, so the skin cracks, flakes and itches.
It is common, and often worse in winter and in centrally heated rooms.
What mainstream guidance suggests
The NHS and dermatology guidance suggest shorter, lukewarm showers, gentle fragrance-free cleansers, and a thick emollient applied to damp skin within minutes of washing, reapplied through the day. Ointments seal best, creams sit in between, and lotions are the lightest.
Where dryness is severe or comes with eczema, a clinician may add a prescribed preparation.
What is not established
No supplement is established for plain dry skin. Moisturising and reducing what dries the skin do the work; a product's value is in its ingredients and how well it seals, not in a claim on the front.
Self-care that is generally suggested
- Shorter, lukewarm showers and baths.
- A gentle, fragrance-free cleanser instead of harsh soap.
- A thick emollient on damp skin straight after washing.
- Reapply through the day, especially to hands and shins.
- A humidifier if the room air is very dry.
- See a clinician if the skin is cracked, bleeding or very itchy.
When to seek care
See a clinician if the skin is cracked, oozing or bleeding, is very itchy, or comes with a rash, because eczema, psoriasis, fungal infection and other conditions need assessing. Seek help urgently for rapidly spreading redness with fever. A child under two with widespread dry or scaly skin should be seen rather than managed with adult products.

Products that may help

Every item below is listed on a property printed on the product label - form, grade, active ingredient, size, runtime or ingredient panel. None is listed because of a claim about your symptom, and none is presented as care. Amazon shows the current price on the linked page.
Pick 1
Plain petroleum jelly
Petroleum jelly is a single-ingredient occlusive that holds water in the skin by forming a barrier. Fragrance-free and dye-free versions are the plainest form.
- Single ingredient, fragrance-free
- Occlusive rather than a lotion
- Jar or tube format

Pick 3
Ceramide moisturiser
A ceramide cream lists its ceramides (NP, AP, EOP) and its humectants - glycerin, hyaluronic acid - on the ingredient panel. Those are the parts worth comparing.
- Ceramides named in the ingredients
- Humectants and occlusives listed
- Fragrance-free option

Pick 4
Colloidal oatmeal bath

- Colloidal oatmeal percentage stated
- Finely milled rather than coarse
- Fragrance-free option

Pick 5
Cool-mist humidifier
The two numbers that decide a humidifier are tank size, which sets how many nights you get between refills, and runtime per fill. A cool-mist unit is chosen over a warm-mist one for rooms with children because it heats no water.
- Tank size in litres
- Runtime per fill in hours
- Cool-mist rather than steam

Questions
Which moisturiser is best for dry skin?
The thickest one you will actually use. Ointments seal best, then creams, then lotions, and fragrance-free versions suit sensitive skin. The ingredient list is the comparison.
Should I moisturise wet or dry skin?
On damp skin within a couple of minutes of washing, so the emollient seals in water rather than sitting on dry flakes.
