Main content

Our skin barrier, also known as the moisture barrier, stratum corneum or acid mantle is made up of the uppermost layers of the skin, it’s watertight and protects the deeper layers of the epidermis from being damaged by irritants. A healthy skin barrier looks plump, hydrated, and smooth, but if the barrier becomes damaged it can feel rough, be red, dry, and uncomfortable. A compromised skin barrier can lead to more issues, as external aggressors like pollution particles make their way to the lower layers of skin, so it’s important to help repair any damage. A consistent skin routine that includes the ingredients and products detailed below will help. It's also important to use lukewarm water when washing your skin, because both cold and hot water can aggravate the skin's natural lipid balance. 

Read our guide to discover the active ingredients and skincare products that will help to soothe and heal your skin barrier function.

Glacial Glycoprotein

Glacial glycoprotein is a naturally occurring compound found deep inside Antarctic glaciers. To survive in such an extreme environment, glacial glycoprotein has to be tough, so it’s no wonder it is a great skin protector. When included in skincare it helps to defend the skin against the drying effects of cold air and can provide long-lasting hydration. Glacial glycoprotein also helps to protect the skin against water loss, leaving it looking smoother and feeling softer over time.

Here at Kiehl’s we synthesise glacial glycoprotein in labs so as not to disturb the delicate balance of the Arctic ecosystem.

Ultra Facial Cream

You’ll find glacial glycoprotein in several of our products, and it’s a key ingredient in our Ultra Facial collection. Soothe and protect your skin barrier by reaching for our Ultra Facial Cream. This bestselling moisturiser provides instant hydration that lasts for up to 24 hours and helps to recover the skin barrier function 55%* faster.

Colloidal Oatmeal

Skin protectant - colloidal oatmeal, is a natural ingredient that helps to calm and soothe dry, stressed skin. Surprisingly, colloidal oatmeal is actually derived directly from the porridge oats you might eat for breakfast, but don’t let that fool you, it’s a multitasking, sophisticated skin ingredient too. It works as an emollient – a treatment that coats skin in moisture to protect it from outside aggressors, while simultaneously working to reinforce the skin barrier. It’s naturally anti-inflammatory which is great for those suffering from uncomfortable skin conditions. Ideal for adding into your skincare routine during the winter months to give skin a softening boost that also protects, it’s a must-have ingredient for dry skin types.

Ultra Facial Advanced Repair Barrier Cream

Our brand new intensive repairing cream has the texture of a daily moisturiser, with the healing power of a balm. Enriched with (the aforementioned), calming, colloidal oatmeal, this fast-absorbing cream instantly relieves skin from redness and itchiness. Ideal for use as a daily moisturiser when the moisture barrier is compromised, this unique new cream instantly hydrates and repairs.

Fatty Acids

The outermost layer of skin, stratum corneum or skin barrier is made up of skin cells, ceramides, and natural fatty acids. The fatty acids or lipids, are essentially natural oils which keep skin hydrated and lubricated. Naturally anti-inflammatory, fatty acids care for the skin barrier and prevent trans-epidermal water loss – they help prevent the skin from drying out. Sensitive skin that feels parched, dry and uncomfortable will benefit from a dose of hydrating fatty acids.

Avocado Nourishing Hydration Mask

To help repair a damaged skin barrier, reach for an intensive skin hydrating mask like our Avocado Nourishing Hydration Mask . Packed with soothing, hydrating ingredients like avocado oil – a natural source of fatty acids that helps to restore the skin’s moisture balance. This rich and creamy mask also contains evening primrose oil which helps maintain skin elasticity.

Beta-Glucan

Meet your new favourite multitasking ingredient! With hydrating powers that have been favourably compared to hyaluronic acid, we predict big things for beta-glucan this year. A polysaccharide or complex sugar that’s derived from yeast, funghi, or seaweed, this antioxidant helps to protect and soothe skin. Beta-Glucan forms an undetectable film over the surface of the complexion to help protect the skin from outside aggressors, while also fighting off any nasty bacteria that mounts an attack. It’s also a humectant, meaning it locks moisture into the skin and prevents dehydration throughout the day.

Ultra Facial Advanced Repair Barrier Cream

Our new Ultra Facial Advanced Repair Barrier Cream helps to soothe uncomfortable, itchy skin, while repairing a damaged skin barrier. Enriched with calming colloidal oatmeal and reparative humectant, beta-glucan. Our rich balm-to-cream formula absorbs quickly to help transform chapped, compromised skin into a soft, smooth surface.

Hyaluronic acid

This powerhouse ingredient is naturally produced by the body and works a bit like a magnet for moisture, pulling water into the skin and holding it within cells so they feel hydrated and plump. It can also be applied topically via skincare, and our skin will recognise it and use it accordingly, so it’s a top ingredient for helping to restore a damaged barrier. It’s also great for improving the look of fine lines and wrinkles, as skin cells filled with water look plumper and in turn, so does the surface of the skin.

Power Strength Pair: Powerful-Strength Line-Reducing & Dark Circle-Diminishing Vitamin C Eye Serum.

Our Powerful-Strength Line-Reducing Concentrate contains hyaluronic acid to help support the moisture barrier while tackling fine lines and wrinkles. It also includes vitamin Cg, a derivative of vitamin C and a powerful antioxidant that activates once absorbed to help skin feel smoother and look more radiant.

It’s formulated specifically for the delicate eye area helping to strengthen, hydrate and brighten.

Glycerin

Glycerin is a humectant, which means it is an ingredient that’s able to pull water into the skin and retain moisture even when cold weather strikes.
