Everything you need to know about the Skin Barrier

The secret to good skin? Your Skin Barrier.

The skin's moisture barrier is EVERYTHING when it comes to your skin health. If the barrier is compromised and not functioning effectively, your skin will send out a cry for help in the form of irritated, red, dry, flakey sensitive skin. A healthy, resilient skin barrier is the secret to good skin. When your skin barrier is functioning effectively:


  • breakouts are less likely
  • the skin can heal faster from any damage
  • you can increase the cadence of active skincare / reduce side effects for sensitive skin
  • and your skin can protect itself against environmental stressors such as bacteria 

The list goes on! So how do we support this wonderwall that keeps our skin fresh and glowy? Read on to learn about what the skin barrier is and how to know if it is damaged.

What is the Skin Barrier

The Skin Barrier or Moisture Barrier (stratum corneum) is exactly that, a protective layer of your skin filled with ceramides, fatty acids, and lipids that acts as a sort of gatekeeper, keeping an eye on and controlling what goes in and what comes out. Sometimes nicknamed ‘bricks and mortar’ due to the fact that it is made up of a collection of sturdy cellular-like structures (corneocytes) and a lipid membrane representing the mortar holding it all together. 


The function of the Skin Barrier

A healthy and resilient skin barrier is most well-known for regulating water content as it absorbs and maintains moisture by preventing transepidermal water loss (TEWL), or dehydration of the skin. Its lesser-known tasks are no less important:

  • Protection from bacteria and
  • Environmental stressors such as pollution
  • Immunity from allergens
  • Oxidant protection
  • Photo-protection from UV light

Without a resilient skin barrier, the skin is susceptible to irritants and damage, so you see why the role of the skin barrier in our journey towards healthy skin is so important. A good, balanced skin care routine will support your skin and ensure it stays strong and resilient.
