Dry-skin marketing loves a rare botanical, but the ingredients that reliably help are mostly unglamorous: glycerin, ceramides, fatty acids and ingredients that reduce water loss. I would take a plain, well-formulated cream over an expensive jar of fragrant extracts every time.
The useful way to shop is to look for three functions. Humectants attract and hold water, emollients soften gaps between rough surface cells, and occlusives slow evaporation. The best hydrating products for dry skin combine all three rather than leaning on one fashionable serum ingredient.
First, check that dryness is actually the problem. Dry skin lacks oil; dehydrated skin lacks water and can still be oily. My guide to dry versus dehydrated skin helps separate the two, while this article focuses on persistently dry, rough or flaky skin.
1. Ceramides, cholesterol and fatty acids
These lipids form part of the organised barrier between skin cells. When that barrier is short of lipids, water escapes more easily and irritants get in. A moisturiser containing ceramides alongside cholesterol and fatty acids can replenish the materials the outer skin needs.
Look for names such as ceramide NP, AP or EOP, cholesterol, linoleic acid and other fatty acids. More ceramide types do not automatically make a product better; the finished formula matters.
CeraVe Moisturising Cream is the obvious affordable example. It combines several ceramides with cholesterol, humectants and occlusives. For the underlying science, read why ceramides are important. I have also covered why hyaluronic acid and ceramides are complementary rather than interchangeable.
2. Glycerin
If I had to choose one humectant, it would be glycerin. It has a long record of use, works across a range of concentrations and is normally well tolerated. It draws and holds water in the upper skin while supporting normal shedding of surface cells.
Glycerin often appears near the top of an ingredient list in lotions and creams. That is more useful than a tiny amount of a headline ingredient added mainly for the front of the box.
3. Hyaluronic acid
Hyaluronic acid is another humectant, often listed as sodium hyaluronate. It can temporarily plump the surface and improve hydration, but it is not a barrier repair ingredient on its own. Molecular-weight claims sound impressive and may affect how a formula feels, yet they are not a good reason to pay triple.
Apply a hyaluronic acid serum to slightly damp skin, then put moisturiser over it. Used alone in a dry environment, a watery serum can evaporate and leave the face feeling tight. My fuller guide to the benefits of hyaluronic acid explains what it can and cannot do.
4. Panthenol
Panthenol, or provitamin B5, works as a humectant and helps support barrier recovery. It is particularly useful when dryness comes with mild stinging or irritation. La Roche-Posay Cicaplast Baume B5+ is a familiar example, although its soothing result comes from the whole balm, not B5 acting alone.
Panthenol is generally easy to combine with retinoids, acids and other treatments. That makes it a practical supporting ingredient rather than another active you have to schedule.
5. Squalane
Squalane is a stable emollient related to squalene, a lipid naturally present in sebum. It softens rough skin and reduces the tight feel without the heaviness of some plant butters. A few drops can be mixed with moisturiser or pressed over it, although a ready-made cream distributes ingredients more evenly.
It is usually well tolerated and not inherently “pore clogging”, but any individual can react to any emollient. The distinction between plant-derived squalane and unstable squalene is covered in my squalane guide.
6. Urea
Urea is part of the skin's natural moisturising factor. At lower cosmetic concentrations, commonly around 2–10%, it hydrates and helps soften rough, scaly texture. Eucerin UreaRepair 5% products are useful examples for stubborn dry patches on face or body.
Higher concentrations are more keratolytic, meaning they loosen thickened surface skin, and are better suited to heels or very rough body areas. Urea can sting cracked or acutely inflamed skin, so I would start with a bland barrier cream until that has settled.
7. Petrolatum and dimethicone
Occlusives are the step dry routines often miss. Petrolatum is exceptionally effective at reducing water loss, inexpensive and chemically stable. Dimethicone gives a lighter, silkier seal and is common in facial moisturisers. Neither “suffocates” skin.
For very dry areas, apply a thin layer of plain petrolatum over moisturiser at night. You do not need to coat an acne-prone face if only the mouth and cheeks are flaky. Occlusion can also increase penetration of products underneath, so I would not seal strong retinoids or acids this way.
How to combine these ingredients
A separate serum for every ingredient is unnecessary. Choose one cream containing a humectant, emollient and occlusive, then add a targeted product only if there is a gap.
A simple routine looks like this:
- Cleanse with a non-foaming or low-foam wash and lukewarm water.
- Apply a glycerin or hyaluronic acid serum to damp skin if extra hydration is needed.
- Follow immediately with a ceramide-rich moisturiser.
- Use petrolatum on the driest areas at night.
- Finish with broad-spectrum SPF 30 or higher in the morning.
My list of moisturisers for dry skin translates these ingredients into specific UK products. If dryness includes burning, new sensitivity and redness, follow a conservative skin barrier repair routine before adding actives.
What dry skin should skip
Denatured alcohol high on the list: it can make a light formula feel elegant but may worsen dryness and stinging. Fatty alcohols such as cetyl, cetearyl and stearyl alcohol are different; they are useful emollients and thickeners.
Strong foaming cleansers: abundant foam and a squeaky finish are not treatment. Choose mild surfactants, cleanse once at night and consider water only in the morning.
Over-exfoliation: daily glycolic acid, scrubs and cleansing brushes remove the surface faster than dry skin can recover. Exfoliation once weekly may be plenty, and none is required while skin is cracked or sore.
Fragrance and essential oils: they do not hydrate. A compromised barrier is also more likely to object to them.
Very hot water: it removes surface lipids and makes post-shower tightness worse.
Dryness that persists despite a gentle routine can come from eczema, psoriasis, medication, weather or an underlying health issue. My overview of skin dryness causes and solutions covers the wider picture. See a GP if skin is severely itchy, weeping, cracked or not improving.

FAQs
What are the best ingredients for dry skin?
Look for glycerin, ceramides, cholesterol, fatty acids, hyaluronic acid, panthenol, squalane, urea and an occlusive such as petrolatum or dimethicone. A balanced cream containing several categories is usually more useful than a single-ingredient serum.
Is hyaluronic acid enough for dry skin?
Usually not. It supplies water-binding hydration but does little to replace missing oil or seal water in. Apply it to damp skin and follow with a cream containing emollients and occlusives.
Are ceramides or glycerin better?
They perform different jobs. Glycerin is a humectant that improves water content; ceramides are lipids that support barrier structure. Dry skin generally benefits from both in the same routine.
Can dry skin use urea every day?
Yes, a low-strength urea moisturiser can be used daily if it feels comfortable. Avoid applying it to cracked, raw or acutely inflamed skin if it stings, and reserve high-strength foot products for thick body skin.
How quickly should hydrating products work?
A good moisturiser should reduce tightness after the first application. Flaking and barrier resilience usually improve over several weeks of consistent, gentle care. If symptoms worsen or remain severe, skincare may not be addressing the cause.
