The importance of Protecting Our Skin Barrier & How to Protect it

The key is balance 

What is the skin Barrier? 

Your skin is made up of layers, each of which performs important functions in protecting your body. 

The outermost layer, called the stratum corneum or lipid barrier is often described as a ‘brick Wall’ this is our fantastic skin barrier our defense mechanism, keeping the right things in and the wrong things out. A Healthy skin barrier means resilient, happy, clear and healthy looking skin.  

Our skin barrier front line of our skin, defends against damaging pollution, UV light, irritants, infection..etc.. Without it all sorts of harmful environmental toxins and pathogens could penetrate the skin and cause havoc in the body. It protects the body from excessive transdermal water loss (TEWL) and hence when the skin barrier is intact will lock in hydration.  

In terms of defense a vital role is the function of the antimicrobial peptides which are produced in the deeper layers of the epidermis and transported to the outermost layer (skin barrier) where these crucial cells defend against potential harmful pathogens. 

Cementing the skin cells together in the skin barrier are ceramides or lipids which work to strengthen the skin.  Ceramides can quickly deteriorate due to a variety of factors, including age, over-exfoliating and more.  

It is so important to understand the function of the skin and realise the importance to maintain its health and function Your skin barrier is essential for good health and needs to be protected in order to function properly.  


 How is your skin barrier compromised?  


While environmental and intrinsic factors (internal conditions) do upset the skin barrier, it’s also the things we do to try and help improve our skin that can tip the balance. Such as:

  • Over cleansing is a major culprit and while it is important to clean our skin over using a product that strips moisture away can start breaking down our ceramides or lipids 
  • Over exfoliation 
  • Over using treatments such as vitamin A  
  • Over use of acids or too strong concentrations (Glycolic, Salicylic acids… more) 
  • Lifestyle issues 
  • Lack of sleep 
  • Stress 
  • Poor diet 
  • UV exposure 
  • Exposure to harsh chemicals 
  • Environments that are either too humid or too dry 
  • Genetics making you more prone to certain skin conditions 


Think about your skin care routines, which products you are using and why, also the frequency. Become your own expert in detecting a damaged skin barrier and how you can repair this. 


How can you tell if your skin barrier is damaged? 


Look out for signs such as:

  • Dehydration 
  • Redness 
  • Stinging skin 
  • Itching 
  • Flaky skin 
  • Acne breakouts 
  • Excess oil 
  • Blackheads 


We now understand the need for a strong skin barrier we must look at our internal and external health, today we are only looking at topical skin products 

 The first step to repairing your damaged skin barrier is to follow the right daily skin routine.  

It is important to identify products that cause damage and make changes to skin care routines, it may mean simplifying routines, using products with a suitable pH, using ingredients that contain ceramides or humectant like hyaluronic acid.   

Skin is unique to you and learning about applying products that will benefit skin repair is crucial to understand, eliminating excessive cleansing, too aggressive treatments and over using is easy to get addicted to as you see a glow in your skin. Yet overtime if harsh products are being used incorrectly or too often, they can potentially lead to damaging the skin barrier and issues associated with this.  

Remember without the protection of our lipid or skin barrier the skin is laid bare to every attack and will become increasingly weaker and the ageing process will accelerate the longer the barrier is left out of balance.  

Finding the balance between your skin type, sensitivity and skin care regime is key..
