You know when you’re buying all the new LE blushes because OMG they’re so pretty and then you end up using the same old one again and again because that’s what works for you?
Urea is like that blush. While you’re getting carried away by all the new skincare bling – Stem cells! EGF! Bee venom! – urea’s the workhorse that’s keeping your skin all soft and glowy.
It deserves a bit more credit, don’t you think? Especially, cos your skin goes south quickly when it doesn’t get enough of it.
Just ask anyone with eczema or psoriasis. Their skin has very little urea and look at how much damage that is wreaking. Ugh.
So, what is this urea thingie and how can you make sure your skin always has all the urea it needs? Read on to find out:
What The Heck Is Urea?
Urea is protein garbage. Literally.
When your body uses protein, it spits out a nitrogenous waste byproduct called urea through sweat and urine (ewww!). Your body doesn’t need it. But your skin…. it can’t get enough of this stuff.
Urea has two super powers: it exfoliates skin AND hydrates it at the same time. Cool, huh?
Healthy, young skin has plenty of urea. But as you get older, your skin makes less of it. That’s one of the reasons why you usually need more hydrating products as you get older.
You know who else needs their extra share of urea? Psoriasis and eczema sufferers. Skin with psoriasis has 40% less urea than healthy skin. Skin with eczema fares even worse: it lacks 85% of the urea it needs!
P.S. The urea in skincare doesn’t come from pee. Phew!
P.P.S. “Urine therapy’ is a thing, though. Please, don’t do it.
What Does Urea Do For The Skin?
Urea is a godsend for dry and troubled skin. It can treat a truckload of skincare conditions, including:
- Contact dermatitis
- Seborrheic dermatitis
Impressive, isn’t it? And it’s all thanks to its super hydrating and exfoliating properties. If you’ve got the patience for the science, here’s how it works:
Urea Is A Powerful Humectant (A.K.A. Hydrator On Steroids)
Let’s get the fancy sciencey jargon out of the way first: a humectant is a moisture magnet. Its job is to attract moisture from the air and bind it to your skin to keep it hydrated.
Hyaluronic acid and glycerin are the most famous member of the humectant family but urea has got what it takes to give them a good run for their money.
You see, not only urea readily absorbs water, it also has a very high water content itself. That means it can hold a truckload of moisture in the skin.
The Koreans aren’t bluffing when they say moisture is the fountain of youth. When your skin is well-hydrated and has all the moisture it needs, it functions better.
All this moisture plumps out your skin, so your fine lines and wrinkles look smaller. It smooths out skin, giving it a softer texture. It provides instant relief to dry, itchy skin and nurses it back to health. It makes it glow.
You can use all the antiaging superstars money can buy, but if you get the hydration part wrong, your skin is never going to look good. Never.

Urea Is A Natural Exfoliant
Urea works a bit differently from other exfoliants.
While scrubs manually remove dead cells from your skin and acids chemically dissolve the “glue” that keeps them stuck together, urea works with the ingredients that make up the molecular structure of the skin.
Together, they regulates the skin’s cellular turnover, i.e. its natural exfoliating process. In other words, it makes sure dead cells slough off when they’re supposed to.
That doesn’t just make your skin smoother and brighter. It strengthens the skin’s protective barrier, too, so that moisture stays in and germs and other skin’s enemies stay out.
You see now why it’s so great for dry skin, psoriasis, eczema and all kinds of skin problems really?

What Else Can Urea Do For Your Skin?
Hydration and exfoliation are urea’s main superpowers. But there’s a lot more this little molecule can do:
- It boosts the activity of LL-37, an antimicrobial peptide that can kill acne bacteria
- It inhibits malassezia, the fungus involved in fungal acne, psoriasis, eczema etc
- It has anti-itching properties
- It has a local anesthetic effect on the skin that helps reduce inflammation and flare-ups
If your skin is in some kind of trouble – eczema, acne, psoriasis, Sahara-like dryness, you name it – urea may just be the thing it needs.
