Corneotherapy - what is it?

July 11, 2019


Glow Skin + Body girls (and guys), we’re starting this blog off by introducing Corneotherapy. Quite an interesting, quite an essential, piece of information. 


Corneotherapy is the method Glow Skin + Body use. Rather than focusing on a generic skincare approach, we use the science of cosmeceuticals. Our core principle is imbedded in the repair and maintenance of the skin barrier defence systems. To start off, the skin is a protective layer, a barrier, a buffer, a controller and a sensor, it’s also largely a part of our appearance. Corneotherapy isn’t a simple topic, you won’t learn everything from this one blog, nor will you learn everything there is to know about skin from vague googling and the words of YouTube beauty vloggers. I’m going to give it a shot though.

The structure of our skin has three layers, the epidermis, dermis and subcutaneous tissue. Peeling back the basics of skin, we’re talking about corneotherapy as being the link between dermatology and cosmetics, encompassing all three structures. If we treat the first defence, we’re treating all three. The therapy we use, focuses on the anatomy, physiology and biology of the Stratum Corneum (SC), which is the outermost layer of the skin. The SC is a crucial part of the skin, contrary to popular belief, recent research indicates that the SC acts as the first defence, the barrier of our skin, into our body. Rather than stripping away the first line of defence and classifying it as “dead skin cells”, we look at your skin, we assess your skin, and we build life back into that first barrier.

Let’s use a relatable example here. Every time I jump on a flight, it’s usually for an important occasion (a function, a birthday, business), and every time I jump off said flight, I’m left with terrible skin. I’ve just been exposed to an extreme environment change, a dry environment. Dry air tends to send our skin into overdrive, which isn’t ideal when I have some place to be and want to look my absolute best! Then again, this isn’t a new discovery. This happens more often than not, so I live, I learn, and I still get on those flights! Skin that is exposed to hot and dry environments exhibit strong barrier functions and low basal transepidermal water loss (TEWL). An increase in the TEWL, the less effective the skin barrier. TEWL is the quantity of water that passively evaporates through the skin to the external environment. Consequently, the increase, or decrease in the TEWL is affected by both internal and external factors. This is not a new discovery, nor is the effect TEWL has on our skin. As we do, both fortunately and unfortunately, live in ever-changing environments, we need to treat our skin as such.


Corneotherapy aims to create that equilibrium and balance of the skin – so our skincare routines, our therapies and our facials are designed and created to recover that barrier of skin, which in turn, repairs the underlying dermal structures. Essentially, balancing the TEWL. A healthy skin barrier provides protection against a variety of external factors. We’re talking dehydration, the penetration of germs, allergens and irritants (including skincare routines, moisturisers, cosmetics).
Healing of inflammation and other skin problems are supported by corneotherapy as we build a strong defence barrier on your skin, for your skin. What’s important to us is managing and restoring that equilibrium. Environmental factors are everchanging, and the skin transitions with atmospheric changes to maintain those moisture levels. Extreme changes begin to stress the skin (e.g. jumping on a flight) and as mentioned earlier, external factors. It’s not impossible to manage, treat and create that equilibrium which is where corneotherapy comes into play.

Corneotherapy delves deeper into the dermatological and cosmetic world, it encompasses more than the SC, TEWL and every other acronym you could imagine. This series will touch on the skin in general, dermatology, anti-aging, rosacea, acne and the most common concerns our patients approach us with.

Stay tuned, stay hydrated.
