Protecting your skins barrier

Protecting your skins barrier

The skin’s barrier function is effectively our body’s first line of external defence, protecting us from the external environment, infections and water loss.

The barrier function is critical to skin health. It can be thinned out and compromised by environmental factors, diet and choices in our skincare.  

There’s certainly something to be said about having ‘thick skin!’

When the structure is compromised, gaps can start forming in the lipid barrier causing trans-epidermal moisture loss. This results in dryness, dullness, wrinkles and skin irritation as allergens and microbes penetrate the dermal layers via those gaps.

The skin barrier function can be impacted by:

  • Environmental factors such as wind, sun and humidity
  • Harsh skincare products containing high SD alcohol or SLS
  • Dietary factors including excessive caffeine, salt and alcohol
  • Insufficient water intake
  • Stress
  • Age – the regenerative and oil production of the skin declines with age

Here are some practical tips on how to protect the skin barrier function:


Avoid products that dry out the skin such as SD alcohol, denatured alcohol and isopropyl alcohol


Use a natural and gentle face cleanser instead of products containing SLS or soaps as they have an alkalising effect on your skin. The pH of the skin should stay somewhere around the acidic mark of around 4.7, which is the ideal pH for good bacterial flora, whereas an alkaline pH of 8-9 disperses good bacteria from the skin


Avoid harsh exfoliants or scrubbing too often. Use only natural exfoliating formulations. 


Wash with warm water instead of hot water that can be very drying on the skin


Layer your skincare routine. Incorporate a toner, serum and moisturiser. The multi layers help protect against moisture loss


Nourish your skin with natural skincare products that are rich in natural sources of essential fatty acids, vitamins ACE, antioxidants and humectants. Make each drop count towards nourishing and hydrating


Maintain a healthy diet. No external nourishment can compete with a varied and healthy diet from within. Adopt a lifelong focus on healthy gut health and healthy skin will follow


Drink enough water. Our skin, like all the other cells in our body, is made up of 70% water 


Protect the skin from harsh elements like wind and UV rays. Use a natural zinc based sunscreen and cover up whenever possible 


Manage your stress. Stress creates an inflammatory response throughout the body, often leading to skin irritations. The stress hormone cortisol not only breaks down collagen but also slows the skin’s ability to regenerate, thereby compromising the barrier function 

Protecting the skin barrier is vital for our health. The stronger and sturdier our skin barrier is, the better it can perform as a ‘defensive wall’ to the toxins we’re exposed to on a daily basis.
