Beauty buzzwords are thrown around all the time; it can be hard to keep up and to know what’s worth exploring further. We’re here to break down the industry’s latest obsession by tackling the science, talking to skincare and makeup pros, and getting real about what works and what doesn’t.

We’re seeing a lot of chat about skincare filled to bursting with ceramides, but just what are they, and why are they so beneficial?

Let’s break it down…

Those with excessively dry skin will have no doubt come across ceramides while hunting for a moisturiser to quench parched patches, but unlike hyaluronic acid or argan and avocado oils, they’re unsung heroes when it comes to skin and body care.

“Ceramides are one of the components – alongside cholesterol and free fatty acids – that hold the skin barrier together,” says Carl Thornfeldt, dermatologist and founder of Epionce skincare, something dermatologist Dr. Justine Hextall, on behalf of the Harley Medical Group, expands on.

“Ceramides are the major lipid or fat constituents present in between skin cells,” she says. “If this structure is strong and healthy, then the skin barrier is more effective, for example, at retaining water.”

Think of them as scaffolding between skin cells. Human skin actually produces ceramides naturally, but no thanks to excessive dryness, environmental factors and growing older, the levels need replenishing. When ceramide reserves are running low, skin becomes dry, inflamed, itchy and irritated, which can lead to skin conditions such as atopic dermatitis or eczema.

So, we know that ceramides are pretty much essential for healthy, happy skin, but what do they actually do when applied topically?

“Ceramides restore skin water permeability (basically moisture in the skin) as well as barrier function,” explains Dr. Hextall. “Recent studies have suggested that low skin ceramide levels is a major factor in skin diseases, such as in atopic dermatitis, so ceramides in skincare products can help replace lipids that have been lost,” she adds. “The role of ceramides is crucial here, as not only do they hydrate and calm the skin but, as they are part of the skin barrier, they start to repair it.”

Persistently rough, cracked, sore skin? They’re a key ingredient for eczema sufferers, too.

“Barrier function plays a significant role in the cause of eczema,” says Dr. Hextall, “so repairing the skin barrier is crucial to reduce skin flares.”

You only have to incorporate a ceramide-packed moisturiser into your skin and body care routine to realise just how fantastic they are at alleviating skin concerns, but there is so much research behind those little invisible cell builders, too.

“There is considerable scientific literature (spanning the past two decades) describing their critical role in the maintenance of an effective skin barrier function,” explains Dr. Christopher Hensby, expert for CeraVe.

“We know that ceramides are extremely effective at treating dermatitis-prone skin,” adds Dr. Hextall. “As we can see from many studies, if ceramides are applied particularly in combination with other lipids, eg. cholesterol and free fatty acids in a combination similar to that found in the skin barrier, this further enhances barrier repair. In fact, I always suggest my patients look for ceramides in skin creams.”

This is something Dr. Thornfeldt seconds: “For the skin to be healthy, it needs more than just ‘moisturisation’,” he says. “The skin barrier should be healthy and intact.” And ceramides are more or less the cement that keeps it together.

While prescription emollient creams such as Diprobase and Dermol are often effective at minimising the symptoms of dry skin conditions, they are less likely to restore the skin’s barrier than a moisturiser that harnesses ceramides. In fact, scientists have discovered that ceramides 1, 3 and 6-11 (often lacking in skin that is prone to eczema and dermatitis) help repair the skin’s barrier in particular.

R29’s beauty editor pinpoints this dermatologist-formulated, multipurpose moisturising cream as the only product that had the ability to get rid of her under-eye eczema. An army of ceramides, hyaluronic acid and glycerin gets to work on banishing dry, tight and irritated skin almost instantly. The oil-free formula dries to a silky but matte finish, so you can apply makeup without any slips and pull on your clothes without getting stuck in them.

Inspired by Epionce brand founder Dr. Thornfeldt’s own personal experience of eczema as a child, this cream combines a trio of ceramides, cholesterol and colloidal oatmeal (all brilliantly moisturising ingredients), to soothe itching, reduce inflammation and to treat dryness from the inside out. A little goes a long way.

Sans fragrance, oil and silicone, even a light layer of this cream provides instant relief from tight, cracked, flaky skin, and it’s all down to the ceramide precursors, which kickstart the skin’s own ceramide reserves. Use it as a facial moisturiser and a hand cream to banish dryness.
