The research behind our Hydroxyethyl Urea Body Cream

What urea does for rough, dry skin, why our cream uses hydroxyethyl urea instead, what 2% panthenol and three other humectants add, and what the research does and doesn't prove.

Rough elbows, dry shins and hard heels are some of the most common skin complaints there are, and some of the easiest to improve. The ingredient most dermatologists reach for first is urea. Our body cream contains a close relative of it, and this guide explains exactly what that means.

We go through what urea does, why our cream uses hydroxyethyl urea, what the 2% panthenol and the other humectants add, and where the evidence is strong or thin. If you only want the product, the body cream page has everything in one place. If you are choosing between our two body creams, this short guide helps.

01Why skin gets rough and dry

The outer layer of your skin is made of flat, dead cells that are shed and replaced all the time. To stay soft and flexible, this layer needs water, and it holds that water with a mix of small molecules called natural moisturising factor, or NMF, and with lipids between the cells.

When NMF and lipids run low, the outer layer dries out. Dry cells don't shed properly, so they pile up into rough, flaky, sometimes greyish patches. Elbows, knees, shins and heels are hit hardest, because they have fewer oil glands and more friction. Winter heating, hot showers, strong soaps and age all make it worse.

A good body cream does two things: it puts water-binding molecules back into the outer layer, and it adds lipids that slow water loss. Urea, and ingredients like it, do the first job.

02What urea does in the skin

Urea is part of the skin's own NMF. It is a small, water-loving molecule that attracts and holds water in the outer layer. Applied in a cream, it tops up that supply. At higher concentrations it also loosens the bonds between the dead cells that make rough skin feel thick, which helps them shed.

This is why urea has been used in dermatology for decades, from gentle everyday lotions to strong creams for calluses and thickened nails.

03Urea by strength

These bands are approximate; reviews of urea describe a gradual shift from moisturising to softening as the concentration rises. We explain them in more detail in 5%, 10% or 40% urea: how much do you need?

04The human evidence for urea

05Hydroxyethyl urea, and why we're telling you

Hydroxyethyl urea is urea with a small hydroxyethyl group attached. That change makes it a strong humectant with a lighter, less sticky feel than glycerin, and it is used in body lotions for exactly that reason.

It is not the same molecule as urea. The decades of research on urea, especially its softening effect at 10% and above, were done on plain urea. We found only limited published research on hydroxyethyl urea, most of it from the companies that make it.

06How we rate the evidence

None of these studies tested our body cream. They tested ingredients, usually in other products. We use them to explain why each ingredient is there, and we say what each one doesn't prove.

07Panthenol (pro-vitamin B5)

Panthenol is the second hero ingredient and, at 2%, one of the few in the cream with a stated percentage. In the skin it is converted to pantothenic acid, vitamin B5, which cells use in making lipids. It is also a humectant in its own right.

A review marking seventy years of dexpanthenol use summarised a broad body of research on its moisturising and barrier-supporting effects, much of it on medicinal creams at 5%. That review is useful background. It doesn't test our cream.

08Glycerin

Glycerin, the third ingredient, is the most studied humectant in skincare. A detailed review concluded that glycerol improves hydration of the outer layer and supports barrier function. It works alongside hydroxyethyl urea: both pull water into the skin, and hydroxyethyl urea reduces some of the stickiness a high glycerin level can bring.

09Sodium PCA

10A little hyaluronic acid

Sodium hyaluronate, a form of hyaluronic acid, sits near the end of the list. It holds water on the surface of the skin and adds to the smooth feel. In a body cream at this position, we count it as a finishing touch rather than a main active.

11Sunflower seed oil

The second ingredient is organic sunflower seed oil, a light oil rich in linoleic acid, a fatty acid the skin uses to build its barrier lipids.

12The emollients: why it absorbs fast

Rich body creams often feel greasy because they rely on heavy oils and waxes. This one uses lighter emollients: two plant triglycerides (caprylic/capric triglyceride and a caprylic/capric/myristic/stearic blend) and dicaprylyl carbonate, which spreads easily and leaves a dry, silky finish. Cetearyl alcohol, a fatty alcohol from plant oils, thickens the cream; it is not a drying alcohol.

The result is a cream that feels rich going on and absorbs quickly, so you can get dressed straight away.

13Vitamin E and a vitamin C ester

Tocopherol (vitamin E) and ascorbyl palmitate (an oil-soluble form of vitamin C) are near the end of the list. Their main job is to protect the sunflower oil from going rancid. We don't market this cream on vitamin C or E, because at these levels they are there for the formula, not for your skin.

14The scent, and all ten allergens

The cream has a fresh cucumber and citrus scent from Parfum and three essential oils: bergamot, bitter orange and ylang-ylang. In 2023 the EU made its list of fragrance allergens that must be named on labels much longer, and essential oils such as bergamot, bitter orange and ylang-ylang are now on it by name. The new rules apply to products placed on the market from July 2026.

So this cream declares ten allergens: Benzyl Salicylate, Limonene, bergamot peel oil, bitter orange peel oil, Citral, Linalool, Linalyl Acetate, Pinene, ylang-ylang oil, and Benzyl Alcohol, which is also used as a preservative. Most people use scented body creams without a problem. If fragrance is a trigger for you, choose our Sensitive Skin Body Cream, which declares five, or a fragrance-free product.

15Citrus oils and sunlight

Bergamot and some other citrus peel oils can contain natural compounds that make skin react more strongly to sunlight. Many cosmetic grades have these compounds removed, and EU rules limit them. We have asked for confirmation of the grade used in our cream. Until we have it, our advice is simple: apply it in the evening, or let it absorb fully before strong sun, and skip sunbeds straight after applying.

16Where to use it

Use it anywhere on the body that feels dry: legs, arms, back of the hands, and especially elbows, knees and heels. On very rough spots, apply a little extra and massage it in. It is not made for the face; the scent and essential oils make it a poor choice there.

Don't apply it to cracked, bleeding or broken skin. If you have diabetes and dry or cracked feet, speak to your doctor or podiatrist before using any foot cream.

17How to use it for best results

• Wash with a mild cleanser and lukewarm water. Our Face & Body Cleanser suits it.
• Pat dry, leaving the skin slightly damp. Humectants work best when there is water to hold on to.
• Massage a generous amount over dry areas, with extra on elbows, knees and heels.
• Repeat once or twice a day. Rough skin improves with daily use and comes back when you stop.

Used daily over the whole body, a 280 ml bottle lasts around four weeks. On elbows, knees and heels only, it lasts much longer.

18When to see a doctor instead

A body cream is for everyday dry, rough skin. See a doctor or pharmacist if your skin cracks or bleeds, itches badly, has red, inflamed patches, or doesn't improve after a few weeks of daily moisturising. Those can be signs of eczema, psoriasis or another condition that needs proper care.

19Body skin through the year

Body skin is often at its driest in winter, when cold air outside and heating inside pull water from the skin, and people take longer, hotter showers. Many people find their shins and forearms flake from November to March and improve in summer. Others find the opposite: sun, sea water, chlorine and air conditioning dry them out in July.

The fix is the same in both cases: keep showers lukewarm and short, moisturise every day rather than when you remember, and use a little more on the areas that always get rough. A cream that absorbs fast makes the daily habit easier to keep.

20Three myths about dry body skin

"Scrubbing will fix rough skin." Scrubbing lifts flakes for a day, but it doesn't replace the water and lipids the skin is missing, and overdoing it makes dryness worse. Moisturising daily does more.

"Oil is the best moisturiser." Oils soften the surface and slow water loss, but they don't add water. Rough skin usually needs humectants as well, which is why this cream combines both.

"If it stings, it's working." Stinging means the skin is irritated or broken. Stop, and see a pharmacist if it continues.

21Who it suits, and who should skip it

It suits you if your elbows, knees, heels or shins feel rough and dry; you want a body cream that absorbs fast; you like a fresh citrus scent; and you want every ingredient and allergen named.

Skip it, or check first, if you need a fragrance-free product; you want plain urea at 10% or more; you react to citrus oils or will be in strong sun straight after applying; or you have broken skin or a skin condition.

22What it adds up to

This is a fast-absorbing body cream built around hydration. It combines four humectants, hydroxyethyl urea, glycerin, sodium PCA and hyaluronic acid, with 2% panthenol, which has good human evidence for reducing water loss, and a light organic sunflower oil. It is scented, with ten declared allergens.

It is not a plain urea cream, and we don't pretend it is. The strongest urea evidence doesn't apply to it. What it offers is a pleasant, effective daily moisturiser for rough, dry skin, with an honest label. If that is what you need, it is a good choice.
