Find out why your skin barrier function is important and how you can keep it healthy.

As its name suggests, the skin’s moisture barrier is your first line of defence against external threats. It consists of the epidermis, which is made up of five layers including the outermost layer of your skin known as the stratum corneum. This has your skin’s toughest job, protecting your body. When it is at its healthiest, it will keep bad things like pollution and pathogens out and good things like moisture in. It’s made up of lipids (oils), fatty acids and ceramides, which it needs to function properly.


1. What can damage your skin barrier function?

Your skin barrier function is faced with a number of external and internal threats on a daily basis. Allergens, irritants and pollutants can all affect the balance of the stratum corneum, plus very cold weather, strong winds and UV exposure can damage skin too. Your lifestyle and age can also have an impact on your skin barrier function. Your skin thins with age and a thinner barrier is a weaker one. Over-exfoliation and over-washing as well as using the wrong skincare products can all strip your skin of moisture and disrupt its barrier function. At Kiehl's skin health is imperative and we've developed our Instant Skin Reader which will help you to find the right routine personalised to your skin type. At all Kiehl’s stores, we offer a complementary skin analysis with our Healthy Skin Assessment Tool to evaluate the hydration and skin barrier strength levels of your skin. Plus, some Kiehl’s stores offer complimentary Derma Reader Skin Analysis, this advanced skin analysis tool has been developed with dermatologists and will give your skin a multi aspects analysis with a recommendation of a routine personalised to your skin conditions, you can book at the store nearest you here.

2. How can you tell if your skin barrier is damaged?

A healthy skin barrier function will retain moisture and stay hydrated, which will mean skin looks younger and more radiant. An impaired moisture barrier function will do the opposite and can leave you with sensitive skin and a tight, dry and dull-looking complexion. You may experience uncomfortable dry skin, tightness and itchiness, redness, flaky skin or breakouts, so it’s well worth focusing on strengthening your skin barrier.
